Covid-19 Points of Leverage, Travel Bans and Eradication

#Don'tFlattenTheCurve

The optimal strategy to defeat the disease is currently the subject of much debate. Several strategies have emerged, and a popular meme right now is #flattenthecurve. The idea of flattening the curve is that if we increase the duration of the pandemic, the number of people infected at any one time will be lower and our ability to treat people properly will be increased. People put a lot of time into creating convincing memes and diagrams showing how this works:



Unfortunately people didn't put much effort into getting the numbers right. Every single one of these diagrams is a steaming pile of nonsense because the line for "Healthcare System Capacity" is about 20-50 times too high, which was first pointed out by Joshua Bach. That tiny red line right next to the x-axis is our health system capacity:


(taken from The Imperial College COVID-19 Response Team's latest report ).

The UK government's "herd immunity" strategy was another possible way forward, but the government reversed course on this when they realized it would involve at least a few hundred thousand deaths.

Contain and Eradicate

In my opinion, the correct strategy to beat covid-19 whilst minimizing losses from this point forward is a contain-and-eradicate strategy. The New England Complex Systems Institute's writeup on this, written by Nassim Nicholas Taleb of Black Swan fame outlines the strategy:
Since lockdowns result in exponentially decreasing numbers of cases, a comparatively short amount of time can be sufficient to achieve pathogen extinction, after which relaxing restrictions can be done without resurgence. ... 
Finally, the use of geographic boundaries and travel restrictions allows for effective and comparatively low cost imposition and relaxation of interventions. Such a multi-scale approach accelerates response efforts, reduces social impacts, allows for relaxing restrictions in areas earlier that are less affected, enables uninfected areas to assist in response in the ares that are infected, and is a much more practical and effective way to stop otherwise devastating outbreaks. ... 
A few other issues are of importance: They ignore the possibility of superspreader events in gatherings by not including the fat tail distribution of contagion in their model. This leads them to deny the importance of banning them, which has been shown to be incorrect, including in South Korea. Cutting the fat tail of the infection distribution is critical to reducing R0.
Basically:

- Close borders and limit internal travel, lockdown and hygiene to drive R0 below 1

- Ban large events to cut off the long tail of the R0 distribution

- Use aggressive testing and contact tracing to clean up any remaining holdouts, and eradicate the virus on a region-by-region and country-by-country level.

- "Green" regions can return to mostly normal life, albeit without large events and travel. That means that people can go back to work and we can reverse the economic damage.

Contain-and-eradicate probably results in both less loss of life and less economic damage than any other strategy, and we can see this as a consequence of taking an exponential process and fighting it in the low orders of magnitude rather than the high ones. Flatten-The-Curve is bad because a flat curve that lasts for a long time is still, in log-terms, almost at the maximum power of the virus and therefore it can do huge amounts of damage. Herd-Immunity and Deliberate-Infection are bad for the same reason. The only other sensible plan I have seen is the idea of rushing a vaccine as quickly as possible, but that is beyond my expertise.

Coronavirus: The Hammer and the Dance

This article follows Coronavirus: Why You Must Act Now, with over 40 million views and 30 translations. If you agree with this article, consider signing the corresponding White House petition. Over 30 translations available at the bottom. Running list of endorsements here. Over 10 million views so far.

Summary of the article: Strong coronavirus measures today should only last a few weeks, there shouldn’t be a big peak of infections afterwards, and it can all be done for a reasonable cost to society, saving millions of lives along the way. If we don’t take these measures, tens of millions will be infected, many will die, along with anybody else that requires intensive care, because the healthcare system will have collapsed.

Within a week, countries around the world have gone from: “This coronavirus thing is not a big deal” to declaring the state of emergency. Yet many countries are still not doing much. Why?

Every country is asking the same question: How should we respond? The answer is not obvious to them.

Some countries, like France, Spain or Philippines, have since ordered heavy lockdowns. Others, like the US, UK, or Switzerland, have dragged their feet, hesitantly venturing into social distancing measures.

Here’s what we’re going to cover today, again with lots of charts, data and models with plenty of sources:
What’s the current situation?
What options do we have?
What’s the one thing that matters now: Time
What does a good coronavirus strategy look like?
How should we think about the economic and social impacts?

When you’re done reading the article, this is what you’ll take away:

Our healthcare system is already collapsing.
Countries have two options: either they fight it hard now, or they will suffer a massive epidemic.
If they choose the epidemic, hundreds of thousands will die. In some countries, millions.
And that might not even eliminate further waves of infections.
If we fight hard now, we will curb the deaths.
We will relieve our healthcare system.
We will prepare better.
We will learn.
The world has never learned as fast about anything, ever.
And we need it, because we know so little about this virus.
All of this will achieve something critical: Buy Us Time.

If we choose to fight hard, the fight will be sudden, then gradual.
We will be locked in for weeks, not months.
Then, we will get more and more freedoms back.
It might not be back to normal immediately.
But it will be close, and eventually back to normal.
And we can do all that while considering the rest of the economy too.

Ok, let’s do this.

1. What’s the situation?

Life Will Eventually Go Back to Being Normal-Bad Again

In a matter of weeks, the coronavirus outbreak has fundamentally changed American life. Businesses and schools have closed indefinitely, and hundreds of thousands of people have lost their jobs. As the economy continues to crash, everyday life feels more precarious than it ever has before. To help, government officials across the country are proposing a slew of benefits, such as a moratorium on evictions and mortgage payments, student loan deferments, releasing prisoners from crowded jails, moving unhoused citizens into hotels and unused apartment buildings, and sending a check to every American citizen for as long as this pandemic lasts.

These unprecedented actions have bipartisan support, as both sides of the aisle understand them to be necessary to address this national emergency. And while I know how scared Americans are feeling, I want to make one thing clear: we will weather this storm. Once the quarantine is lifted and a COVID-19 vaccine is developed, it will once again be business as usual. All the benefits you’ve come to rely on will go away, we will cut the social safety net we hastily assembled, and life will return to normal. As terrifying as things are now, we will persevere and return to the normal terror we’re used to.

We are not underestimating the devastating effects of COVID-19. We are taking this virus seriously, and help is on the way. We are in the process of implementing many left-wing policies — universal income, debt relief, free healthcare, reducing the prison population — that were unfathomable just a month ago. But I want to stress to all Americans that these policies are only temporary. While we might make coronavirus testing, and possibly even treatment, free of charge, rest assured, once this blows over, you will continue to go into debt for any other health issue. Nothing can stop the American way of life, not even a pandemic. We will not let this virus prevent our insurance companies from gouging us for basic services the way our Founding Fathers intended. (...)

Some of you might be wondering, why can’t we take this opportunity to address our country’s issues, create a strong welfare state, and change society for the better? I hear your concerns, but it’s a slippery slope. Once we start being decent, there’s no going back. If Americans aren’t one missed payment away from losing their home, people are going to be kind to one another on a scale we’ve never seen before. Neighbors will help neighbors. Young people will look after older people. Quality of life could skyrocket to levels we haven’t seen since before the invention of capitalism. It’s complete and utter altruism, and it will tear us apart. The sooner we go back to fucking each other over, the better.

Give Us This Day Our Daily Bread: Coronavirus and Food Security

As Bloomberg reports in Countries Starting to Hoard Food, Threatening Global Trade:
It’s not just grocery shoppers who are hoarding pantry staples. Some governments are moving to secure domestic food supplies during the conoravirus pandemic. 
Kazakhstan, one of the world’s biggest shippers of wheat flour, banned exports of that product along with others, including carrots, sugar and potatoes. Vietnam temporarily suspended new rice export contracts. Serbia has stopped the flow of its sunflower oil and other goods, while Russia is leaving the door open to shipment bans and said it’s assessing the situation weekly. 
To be perfectly clear, there have been just a handful of moves and no sure signs that much more is on the horizon. Still, what’s been happening has raised a question: Is this the start of a wave of food nationalism that will further disrupt supply chains and trade flows?
Yesterday, the United Nations warned that coronavirus measures could lead to food shortages, as The Guardian reports in Coronavirus measures could cause global food shortage, UN warns:
Protectionist measures by national governments during the coronavirus crisis could provoke food shortages around the world, the UN’s food body has warned. 
Harvests have been good and the outlook for staple crops is promising, but a shortage of field workers brought on by the virus crisis and a move towards protectionism – tariffs and export bans – mean problems could quickly appear in the coming weeks, Maximo Torero, chief economist of the UN Food and Agriculture Organisation, told the Guardian. 
“The worst that can happen is that governments restrict the flow of food,” he said. “All measures against free trade will be counterproductive. Now is not the time for restrictions or putting in place trade barriers. Now is the time to protect the flow of food around the world.”
At present, the UN’s warning is ominous, but not dire. Yet the food shortage threat will only increase, as the coronavirus crisis continues, and the northern hemisphere moves into the heart of its growing season. Encore for The Guardian:
While the supply of food is functioning well in most countries at present, problems could start to be seen within weeks and intensify over the following two months as key fruit and vegetables come into season. These types of produce often have short ripening times and are highly perishable, and need skilled pickers to work quickly at the right time. 
“We need to be careful not to break the food value chain and the logistics or we will be looking at problems with fresh vegetables and fruits soon,” said Torero. “Fruit and vegetables are also very labour intensive, if the labour force is threatened because people can’t move then you have a problem.” 
As governments impose lockdowns in countries across the world, recruiting seasonal workers will become impossible unless measures are taken to ensure vital workers can still move around, while preventing the virus from spreading. 
“Coronavirus is affecting the labour force and the logistical problems are becoming very important,” said Torero. “We need to have policies in place so the labour force can keep doing their job. Protect people too, but we need the labour force. Major countries have yet to implement these sorts of policies to ensure that food can keep moving.” 
Countries such as the UK, with a sinking currency and high level of imports, are also likely to see food price rises unless the government takes action or retailers absorb some of the costs, he said. 
The most important role governments can play is to keep the food supply chain operating, intervene to ensure there are enough workers, and keep the global food markets from panicking, according to Torero. 
“If traders start to become nervous, conditions will get difficult,” he said. “It just needs one big trader to make a decision [to disrupt the supply of staple crops] and that will affect everywhere. Governments must properly regulate, that is their biggest function in this situation. It’s very important to keep alive the food value chain: intervene to protect the value chain [including the supply of workers] but not to distort the market.”
The United Kingdom

I lived in the United Kingdom for three years prior to my stint in Geneva, and for one one year after. At that time, UK food prices were much lower than Swiss ones. Now, as those who monitored Brexit discussions no doubt already know, the UK is dependent on imports for roughly half of its food, 53 per cent, to be exact.

As Tim Lang writes in The Conversation, Coronavirus: rationing based on health, equity and decency now needed – food system expert:
Food security is no laughing matter at the best of times, but I gasped when I first read the Department for Environment, Food and Rural Affairs’ (Defra) annual food civil contingencies infrastructure report in 2018. It is barely a page long (in public at least) and assures us everything is OK and that the food system is resilient and able to withstand shocks. As the coronvirus racks the nation and panic buying continues, this complacency is about to be tested. 
Few analysts of the UK food system are anything other than sober about its fragility. There is little storage. All operates on a just-in-time basis in which food travels down the supply chain – literally, just in time for when the next link or process needs it. Food businesses have been realigned to cut delays and storage. Consumers have come to expect constant flows of food, without hiccups or gaps. New industries have emerged, notably logistics and satellites which track this all from farm to shop. We are trucker-dependent now. 
Only 53% of food consumed in the UK is produced in the country. Others feed the Brits. Some scientists calculate that UK external dependency is even greater, with hidden use of external land to provide animal feed
While this distortedly efficient food revolution has been rolled out, the UK food trade gap – the difference between exports and imports by value – has widened. In 2018, food worth £46.8 billion was imported, with exports worth only £22.5 billion, leaving a food trade gap of £24.3 billion. Much of the imports are vital for health, the £10bn imports of fruit and veg in particular. UK fruit and veg growing has sunk. The UK’s main “oral” export these days is whisky. Even meat – supposedly Britain’s forte – is in the red. If borders close or supply chains snap, what then?
Lang believes that the UK may soon be facing a food crisis, and calls for the government ito think about imposing a system of rationing, rather than allowing a free for all to ensue.
A crunch point for UK food policy and planning is surely approaching. The coronavirus crisis is already spawning worrying actions. Whereas under Brexit no-deal threats, stoicism ruled and “preppers” – people stocking up – were generally few. Today shelves are being stripped and queues form for supermarkets to open. It’s why colleagues and I have called on the UK prime minister to set up a rational system of rationing – based on health, equity and decency – to see the country through this crisis.
The alternative is for food retailers to engage in de facto rationing, according to whatever principles they care to apply, rather than those that would prevail in a transparent public rationing system. Lang again:
Meanwhile, it is the food retailers who are beginning to ration supply. This is unacceptable in a democracy. If to happen, it ought to be in the open – and guided by health and sustainability. Surely the “public good” lies in feeding all well, according to need not income. Those values are what got the UK through the second world war, as our Churchill-inspired prime minister ought to know.

Gilead Sciences Backs Off Monopoly Claim For Promising Coronavirus Drug

[ed. Previously: Coronavirus Treatment Developed by Gilead Sciences Granted "Rare Disease" Status, Potentially Limiting Affordability (The Intercept/Duck Soup).]

Gilead Sciences on Wednesday announced that it has submitted a request to the Food and Drug Administration to rescind the exclusive marketing rights it had secured for remdesivir, an antiviral drug that shows promise in treating Covid-19, the disease caused by the new coronavirus. As The Intercept reported on Monday, the FDA had awarded Gilead seven years of exclusive marketing rights to the drug through the Orphan Drug Act, even though the statute was designed to induce pharmaceutical companies to make treatments for rare diseases that affect fewer than 200,000 people in the United States.

Although the new coronavirus will almost certainly infect that many people, Gilead had exploited a loophole that grants orphan drug status if a company files for it before the official number of cases hits 200,000. As of Wednesday afternoon, there were more than 438,000 confirmed cases worldwide, with more than 59,000 in the United States.

After a public outcry, Gilead issued a press release stating:
Gilead has submitted a request to the U.S. Food and Drug Administration to rescind the orphan drug designation it was granted for the investigational antiviral remdesivir for the treatment of Covid-19 and is waiving all benefits that accompany the designation. Gilead is confident that it can maintain an expedited timeline in seeking regulatory review of remdesivir, without the orphan drug designation. Recent engagement with regulatory agencies has demonstrated that submissions and review relating to remdesivir for the treatment of Covid-19 are being expedited.
Still, public health experts remain concerned about the potential for Gilead and other pharmaceutical companies to engage in price gouging during the global pandemic. And while pharmaceutical companies are testing dozens of drugs as potential vaccines and treatments for the new coronavirus, some legal scholars have pointed to an obscure statute to help ensure that companies won’t price critical drugs out of reach.

The law, known as Section 1498, gives the government the right to override a patent at any time as long as the company receives “reasonable compensation.” Essentially functioning as a kind of eminent domain for patented products, the provision breaks the monopoly and permits low-cost competition. And if drugs such as Gilead’s antiviral remdesivir and other potential treatments and vaccines for the coronavirus are priced out of reach, it could give the government critical leverage to negotiate lower prices. Through the Defense Production Act, the government could even start producing lifesaving treatments itself.

“The government should use every tool that it has to make sure that any coronavirus treatment or vaccine is affordable, including taking away monopolies through 1498,” said Zain Rizvi, a drug-pricing expert at Public Citizen. (...)

The federal government regularly used Section 1498 in the 1960s and 1970s to purchase generic drugs when the patented versions were far more expensive. But pharmaceutical companies railed against the provision and while it has been used for other inventions it has rarely been used for drugs since. In 2001, during the anthrax scare, just the threat of using 1498 proved effective when the government was trying to secure access to the antibiotic ciprofloxacin, which could be used to treat people who were exposed to anthrax. After then-Secretary of Health and Human Services Tommy Thompson raised the possibility of using the provision, Bayer cut the price of ciprofloxacin in half.

In 2017, a group of academics at Yale Law School made the case for the government’s use of Section 1498 to procure a lifesaving treatment for hepatitis C called Sofosbuvir, also manufactured by Gilead, which is too expensive for many people who need it. Sofosbuvir costs $48,000 for a 24-week course, or about $1,000 a pill. Because of the exorbitant price, insurers have refused to cover it for all of the roughly 5 million people infected with hepatitis C, instead making the drug available to only the sickest patients.

[ed. Amazing what some bad PR and public pressure can accomplish during a crisis. And what obscure information comes to light. Like Section 1498. That's some pretty heavy leverage. Also, just in (Friday 3/27): after endless dithering the President has finally been convinced to use the Defense Production Act to speed up production of ventilators. Why so long? Perhaps because of this. Or this. Or, maybe it's just because he likes haggling.]

Cellphone ‘Heat Map’ Shows Distribution of Florida Spring Breakers After Party


A heat map highlighting cellphone location data within the U.S. is providing a frightening insight into the movements of humans amid the ongoing coronavirus pandemic.

The data, collected by location technology company X-Mode, was recently plugged into the geospatial data visualization platform known as Tectonix as part of an effort to track the coronavirus across the globe.

In just one example of the project’s findings, cellphones on a beach in Fort Lauderdale, Florida, during spring break were selected and tracked. When the festivities ended, the cellphones were seen sprawling out across the Eastern half of the country, potentially bringing cases of the highly contagious virus with them.

X-Mode states that the data used is “anonymized,” meaning a cellphone’s location is not linked to its user’s identity. Tectonix took that raw data and honed in specifically on devices moving between 3 and 10 miles per hour in an attempt to pinpoint cellphone owners believed to be walking or traveling with bikes or scooters.

Aside from Florida, the project has also released its analysis of New York City, which is currently the epicenter of the pandemic in the U.S. Just like Florida, the data on New York, specifically Manhattan, shows widespread movement throughout the month of March.

How to Make Your Own Hand Sanitizer

Properly scrubbing your hands is one of the best ways to stop the spread of germs and viruses, and to ensure you don’t get sick yourself. But if you don't have access to soap and clean water, or if you're out and about and nowhere near a sink, you should carry hand sanitizer to protect your health.

As you're no doubt aware, bottles of hand sanitizer (Purell, Wet Ones, and the like) sell out quickly during public health crises. But don't worry—making your own hand sanitizer is remarkably easy. You just have to be careful you don't mess it up. Make sure that the tools you use for mixing are properly sanitized; otherwise you could contaminate the whole thing. Also, the World Health Organization recommends letting your concoction sit for a minimum of 72 hours after you're done. That way the sanitizer has time to kill any bacteria that might have been introduced during the mixing process.

(Note: To reiterate, nothing beats washing your hands. Hand sanitizer—even the real, professionally made stuff—should always be a last resort.)

We actually have two recipes for you, and links to find the ingredients. The first is one you can make with stuff you likely already have in your cabinets and under the sink, so it's effective in emergency situations. The second recipe is more complex, but easy to make if you have the opportunity to do some shopping and planning ahead of time. Another note: a lot of these items are quickly going out of stock because of high demand. There's a higher chance of finding them at your local drug store, but your first priority is to stay indoors.

Potency Matters

You’re going to need some alcohol. According to the Centers for Disease Control and Prevention, your sanitizer mix must be at least 60 percent alcohol to be effective. But it's better to get way above that—aim for a minimum of 75 percent. A bottle of 99 percent isopropyl alcohol is the best thing to use. Your regular vodka and whiskey are too wimpy and won’t cut it.

The Quick (Gel) Recipe

Isopropyl alcohol (also here)
Aloe vera gel (also here)
Tea tree oil (also here)

Mix 3 parts isopropyl alcohol to 1 part aloe vera gel. Add a few drops of tea tree oil to give it a pleasant scent and to align your chakras.

The aloe mixture gets the job done, but aloe also leaves your skin annoyingly sticky. So, here's a recipe that's less sticky and more potent, based on the mix recommended by the WHO.

Face Masks: Much More Than You Wanted to Know

There’s been recent controversy about the use of face masks for protection against coronavirus. Mainstream sources, including the CDC and most of the media say masks are likely useless and not recommended. They’ve recently been challenged, for example by Professor Zeynep Tufekci in the New York Times and by Jim and Elizabeth on Less Wrong. There was also some debate in the comment section here last week, so I promised I’d look into it in more depth.

As far as I can tell, both sides agree on some points.

They agree that N95 respirators, when properly used by trained professionals, help prevent the wearer from getting infected.

They agree that surgical masks help prevent sick people from infecting others. Since many sick people don’t know they are sick, in an ideal world with unlimited mask supplies everyone would wear surgical masks just to prevent themselves from spreading disease.

They also agree that there’s currently a shortage of both surgical masks and respirators, so for altruistic reasons people should avoid hoarding them and give healthcare workers first dibs.

But they disagree on whether surgical masks alone help prevent the wearer from becoming infected, which will be the focus of the rest of this piece.

1. What are the theoretical reasons why surgical masks might or might not work?

Epidemiologists used to sort disease transmission into three categories: contact, droplet, and airborne. Contact means you only get a disease by touching a victim. This could be literally touching them, or a euphemism for very explicit contact like kissing or sex. Droplet means you get a disease when a victim expels disease-laden particles into your face, usually through coughing, sneezing, or talking. Airborne means you get a disease because it floats in the air and you breathe it in. Transmission via “fomites”, objects like doorknobs and tables that a victim has touched and left their germs on, is a bonus transmission route that can accompany any of these other methods.

More recently, scientists have realized that droplet and airborne transmission exist along more of a spectrum. Droplets can stay in the air for more or less time, and spread through more or less volume of space before settling on the ground. The term for this new droplet-airborne spectrum idea is “aerosol transmission”. Diseases with aerosol transmission may be spread primarily through droplets, but can get inhaled along with the air too. This concept is controversial, with different authorities having different opinions over which viruses can be aerosolized. It looks like most people now believe aerosol transmission is real and applicable to conditions like influenza, SARS, and coronavirus.

Surgical masks are loose pieces of fabric placed in front of the mouth and nose. They offer very good protection against outgoing droplets (eg if you sneeze, you won’t infect other people), and offer some protection against incoming droplets (eg if someone else sneezes, it doesn’t go straight into your nose). They’re not airtight, so they offer no protection against airborne disease or the airborne component of aerosol diseases.

Respirators are tight pieces of fabric that form a seal around your mouth and nose. They have various “ratings”; N95 is the most common, and I’ll be using “N95 respirator” and “respirator” interchangably through most of this post even though that’s not quite correct. When used correctly, they theoretically offer protection against incoming and outgoing droplet and airborne diseases; since aerosol diseases are a combination of these, they offer generalized protection against those too. Hospitals hate the new “aerosol transmission” idea, because it means they probably have to switch from easy/cheap/comfortable surgical masks to hard/expensive/uncomfortable respirators for a lot more diseases.

Theory alone tells us surgical masks should not provide complete protection. Coronavirus has aerosol transmission, so it is partly airborne. Since surgical masks cannot prevent inhalation of airborne particles, they shouldn’t offer 100% safety against coronavirus. But theory doesn’t tell us whether they might not offer 99% safety against coronavirus, and that would still be pretty good.

2. Are people who wear surgical masks less likely to get infected during epidemics?

It’s unethical to randomize people to wear vs. not-wear masks during a pandemic, so nobody has done this. Instead we have case-control studies. After the pandemic is over, scientists look at the health care workers who did vs. didn’t get infected, and see whether the infected people were less likely to wear masks. If so, that suggests maybe the masks helped.

This is an especially bad study design, for two reasons. First, it usually suffers recall bias – if someone wore a mask inconsistently, then they’re more likely to summarize this as “didn’t wear masks” if they got infected, and more likely to summarize it as “did wear masks” if they stayed safe. Second, probably some nurses are responsible and do everything right, and other nurses are irresponsible and do everything wrong, and that means that if anything at all helps (eg washing your hands), then it will look like masks working, since the nurses who washed their hands are more likely to have worn masks. Still, these studies are the best we can do.

[ed. See also: How 3M Plans to Make More Than a Billion Masks By End of Year (Bloomberg). Excerpt:

The N95 respirator is so named because, worn properly, it blocks at least 95% of airborne particles from entering a wearer’s mouth and nose, while still allowing respiration through the microscopically porous shell. This design protects a person from medical and other hazards; flimsier, looser-fitting surgical masks are intended to prevent the wearer from infecting others with expelled mucus, blood, or spit.

3M makes about two dozen versions of the N95, for different industrial and medical purposes. Generally they’re constructed from nonwoven materials—infinitesimal plastic strands blown together to form a random thicket that, under a microscope, “is going to look like pickup sticks,” says Nikki McCullough, 3M’s global leader for occupational health and safety. “If you’re a submicron particle, it’s quite the journey through there.” The filters can block invaders as small as 0.3 microns, or about 1/100th the thickness of a human hair. The virus is smaller than that, at about 0.125 microns, but it often travels within larger particles when an infected person coughs or sneezes.

How the Pandemic Will End

[ed. Important.]

Three months ago, no one knew that SARS-CoV-2 existed. Now the virus has spread to almost every country, infecting at least 446,000 people whom we know about, and many more whom we do not. It has crashed economies and broken health-care systems, filled hospitals and emptied public spaces. It has separated people from their workplaces and their friends. It has disrupted modern society on a scale that most living people have never witnessed. Soon, most everyone in the United States will know someone who has been infected. Like World War II or the 9/11 attacks, this pandemic has already imprinted itself upon the nation’s psyche.

A global pandemic of this scale was inevitable. In recent years, hundreds of health experts have written books, white papers, and op-eds warning of the possibility. Bill Gates has been telling anyone who would listen, including the 18 million viewers of his TED Talk. In 2018, I wrote a story for The Atlantic arguing that America was not ready for the pandemic that would eventually come. In October, the Johns Hopkins Center for Health Security war-gamed what might happen if a new coronavirus swept the globe. And then one did. Hypotheticals became reality. “What if?” became “Now what?”

So, now what? In the late hours of last Wednesday, which now feels like the distant past, I was talking about the pandemic with a pregnant friend who was days away from her due date. We realized that her child might be one of the first of a new cohort who are born into a society profoundly altered by COVID-19. We decided to call them Generation C.

As we’ll see, Gen C’s lives will be shaped by the choices made in the coming weeks, and by the losses we suffer as a result. But first, a brief reckoning. On the Global Health Security Index, a report card that grades every country on its pandemic preparedness, the United States has a score of 83.5—the world’s highest. Rich, strong, developed, America is supposed to be the readiest of nations. That illusion has been shattered. Despite months of advance warning as the virus spread in other countries, when America was finally tested by COVID-19, it failed.

“No matter what, a virus [like SARS-CoV-2] was going to test the resilience of even the most well-equipped health systems,” says Nahid Bhadelia, an infectious-diseases physician at the Boston University School of Medicine. More transmissible and fatal than seasonal influenza, the new coronavirus is also stealthier, spreading from one host to another for several days before triggering obvious symptoms. To contain such a pathogen, nations must develop a test and use it to identify infected people, isolate them, and trace those they’ve had contact with. That is what South Korea, Singapore, and Hong Kong did to tremendous effect. It is what the United States did not.

As my colleagues Alexis Madrigal and Robinson Meyer have reported, the Centers for Disease Control and Prevention developed and distributed a faulty test in February. Independent labs created alternatives, but were mired in bureaucracy from the FDA. In a crucial month when the American caseload shot into the tens of thousands, only hundreds of people were tested. That a biomedical powerhouse like the U.S. should so thoroughly fail to create a very simple diagnostic test was, quite literally, unimaginable. “I’m not aware of any simulations that I or others have run where we [considered] a failure of testing,” says Alexandra Phelan of Georgetown University, who works on legal and policy issues related to infectious diseases.

The testing fiasco was the original sin of America’s pandemic failure, the single flaw that undermined every other countermeasure. If the country could have accurately tracked the spread of the virus, hospitals could have executed their pandemic plans, girding themselves by allocating treatment rooms, ordering extra supplies, tagging in personnel, or assigning specific facilities to deal with COVID-19 cases. None of that happened. Instead, a health-care system that already runs close to full capacity, and that was already challenged by a severe flu season, was suddenly faced with a virus that had been left to spread, untracked, through communities around the country. Overstretched hospitals became overwhelmed. Basic protective equipment, such as masks, gowns, and gloves, began to run out. Beds will soon follow, as will the ventilators that provide oxygen to patients whose lungs are besieged by the virus.

With little room to surge during a crisis, America’s health-care system operates on the assumption that unaffected states can help beleaguered ones in an emergency. That ethic works for localized disasters such as hurricanes or wildfires, but not for a pandemic that is now in all 50 states. Cooperation has given way to competition; some worried hospitals have bought out large quantities of supplies, in the way that panicked consumers have bought out toilet paper.

Partly, that’s because the White House is a ghost town of scientific expertise. A pandemic-preparedness office that was part of the National Security Council was dissolved in 2018. On January 28, Luciana Borio, who was part of that team, urged the government to “act now to prevent an American epidemic,” and specifically to work with the private sector to develop fast, easy diagnostic tests. But with the office shuttered, those warnings were published in The Wall Street Journal, rather than spoken into the president’s ear. Instead of springing into action, America sat idle.

Rudderless, blindsided, lethargic, and uncoordinated, America has mishandled the COVID-19 crisis to a substantially worse degree than what every health expert I’ve spoken with had feared. “Much worse,” said Ron Klain, who coordinated the U.S. response to the West African Ebola outbreak in 2014. “Beyond any expectations we had,” said Lauren Sauer, who works on disaster preparedness at Johns Hopkins Medicine. “As an American, I’m horrified,” said Seth Berkley, who heads Gavi, the Vaccine Alliance. “The U.S. may end up with the worst outbreak in the industrialized world.”

I. The Next Months

Having fallen behind, it will be difficult—but not impossible—for the United States to catch up. To an extent, the near-term future is set because COVID-19 is a slow and long illness. People who were infected several days ago will only start showing symptoms now, even if they isolated themselves in the meantime. Some of those people will enter intensive-care units in early April. As of last weekend, the nation had 17,000 confirmed cases, but the actual number was probably somewhere between 60,000 and 245,000. Numbers are now starting to rise exponentially: As of Wednesday morning, the official case count was 54,000, and the actual case count is unknown. Health-care workers are already seeing worrying signs: dwindling equipment, growing numbers of patients, and doctors and nurses who are themselves becoming infected.

Italy and Spain offer grim warnings about the future. Hospitals are out of room, supplies, and staff. Unable to treat or save everyone, doctors have been forced into the unthinkable: rationing care to patients who are most likely to survive, while letting others die. The U.S. has fewer hospital beds per capita than Italy. A study released by a team at Imperial College London concluded that if the pandemic is left unchecked, those beds will all be full by late April. By the end of June, for every available critical-care bed, there will be roughly 15 COVID-19 patients in need of one. By the end of the summer, the pandemic will have directly killed 2.2 million Americans, notwithstanding those who will indirectly die as hospitals are unable to care for the usual slew of heart attacks, strokes, and car accidents. This is the worst-case scenario. To avert it, four things need to happen—and quickly. (...)

II. The Endgame

Even a perfect response won’t end the pandemic. As long as the virus persists somewhere, there’s a chance that one infected traveler will reignite fresh sparks in countries that have already extinguished their fires. This is already happening in China, Singapore, and other Asian countries that briefly seemed to have the virus under control. Under these conditions, there are three possible endgames: one that’s very unlikely, one that’s very dangerous, and one that’s very long.

The first is that every nation manages to simultaneously bring the virus to heel, as with the original SARS in 2003. Given how widespread the coronavirus pandemic is, and how badly many countries are faring, the odds of worldwide synchronous control seem vanishingly small.

The second is that the virus does what past flu pandemics have done: It burns through the world and leaves behind enough immune survivors that it eventually struggles to find viable hosts. This “herd immunity” scenario would be quick, and thus tempting. But it would also come at a terrible cost: SARS-CoV-2 is more transmissible and fatal than the flu, and it would likely leave behind many millions of corpses and a trail of devastated health systems. The United Kingdom initially seemed to consider this herd-immunity strategy, before backtracking when models revealed the dire consequences. The U.S. now seems to be considering it too.

The third scenario is that the world plays a protracted game of whack-a-mole with the virus, stamping out outbreaks here and there until a vaccine can be produced. This is the best option, but also the longest and most complicated.

It depends, for a start, on making a vaccine. If this were a flu pandemic, that would be easier. The world is experienced at making flu vaccines and does so every year. But there are no existing vaccines for coronaviruses—until now, these viruses seemed to cause diseases that were mild or rare—so researchers must start from scratch. The first steps have been impressively quick. Last Monday, a possible vaccine created by Moderna and the National Institutes of Health went into early clinical testing. That marks a 63-day gap between scientists sequencing the virus’s genes for the first time and doctors injecting a vaccine candidate into a person’s arm. “It’s overwhelmingly the world record,” Fauci said.

But it’s also the fastest step among many subsequent slow ones. The initial trial will simply tell researchers if the vaccine seems safe, and if it can actually mobilize the immune system. Researchers will then need to check that it actually prevents infection from SARS-CoV-2. They’ll need to do animal tests and large-scale trials to ensure that the vaccine doesn’t cause severe side effects. They’ll need to work out what dose is required, how many shots people need, if the vaccine works in elderly people, and if it requires other chemicals to boost its effectiveness.

“Even if it works, they don’t have an easy way to manufacture it at a massive scale,” said Seth Berkley of Gavi. That’s because Moderna is using a new approach to vaccination. Existing vaccines work by providing the body with inactivated or fragmented viruses, allowing the immune system to prep its defenses ahead of time. By contrast, Moderna’s vaccine comprises a sliver of SARS-CoV-2’s genetic material—its RNA. The idea is that the body can use this sliver to build its own viral fragments, which would then form the basis of the immune system’s preparations. This approach works in animals, but is unproven in humans. By contrast, French scientists are trying to modify the existing measles vaccine using fragments of the new coronavirus. “The advantage of that is that if we needed hundreds of doses tomorrow, a lot of plants in the world know how to do it,” Berkley said. No matter which strategy is faster, Berkley and others estimate that it will take 12 to 18 months to develop a proven vaccine, and then longer still to make it, ship it, and inject it into people’s arms.

It’s likely, then, that the new coronavirus will be a lingering part of American life for at least a year, if not much longer. If the current round of social-distancing measures works, the pandemic may ebb enough for things to return to a semblance of normalcy. Offices could fill and bars could bustle. Schools could reopen and friends could reunite. But as the status quo returns, so too will the virus. This doesn’t mean that society must be on continuous lockdown until 2022. But “we need to be prepared to do multiple periods of social distancing,” says Stephen Kissler of Harvard.

Much about the coming years, including the frequency, duration, and timing of social upheavals, depends on two properties of the virus, both of which are currently unknown. First: seasonality. Coronaviruses tend to be winter infections that wane or disappear in the summer. That may also be true for SARS-CoV-2, but seasonal variations might not sufficiently slow the virus when it has so many immunologically naive hosts to infect. “Much of the world is waiting anxiously to see what—if anything—the summer does to transmission in the Northern Hemisphere,” says Maia Majumder of Harvard Medical School and Boston Children’s Hospital.

Second: duration of immunity. When people are infected by the milder human coronaviruses that cause cold-like symptoms, they remain immune for less than a year. By contrast, the few who were infected by the original SARS virus, which was far more severe, stayed immune for much longer. Assuming that SARS-CoV-2 lies somewhere in the middle, people who recover from their encounters might be protected for a couple of years. To confirm that, scientists will need to develop accurate serological tests, which look for the antibodies that confer immunity. They’ll also need to confirm that such antibodies actually stop people from catching or spreading the virus. If so, immune citizens can return to work, care for the vulnerable, and anchor the economy during bouts of social distancing.

Scientists can use the periods between those bouts to develop antiviral drugs—although such drugs are rarely panaceas, and come with possible side effects and the risk of resistance. Hospitals can stockpile the necessary supplies. Testing kits can be widely distributed to catch the virus’s return as quickly as possible. There’s no reason that the U.S. should let SARS-CoV-2 catch it unawares again, and thus no reason that social-distancing measures need to be deployed as broadly and heavy-handedly as they now must be. As Aaron E. Carroll and Ashish Jha recently wrote, “We can keep schools and businesses open as much as possible, closing them quickly when suppression fails, then opening them back up again once the infected are identified and isolated. Instead of playing defense, we could play more offense.”

Whether through accumulating herd immunity or the long-awaited arrival of a vaccine, the virus will find spreading explosively more and more difficult. It’s unlikely to disappear entirely. The vaccine may need to be updated as the virus changes, and people may need to get revaccinated on a regular basis, as they currently do for the flu. Models suggest that the virus might simmer around the world, triggering epidemics every few years or so. “But my hope and expectation is that the severity would decline, and there would be less societal upheaval,” Kissler says. In this future, COVID-19 may become like the flu is today—a recurring scourge of winter. Perhaps it will eventually become so mundane that even though a vaccine exists, large swaths of Gen C won’t bother getting it, forgetting how dramatically their world was molded by its absence.

Tiger King

“Tiger King” is Netflix comfort food of the highest order: it immerses viewers in a mind-boggling lifestyle and series of scandals, and yet the term “true-crime” doesn’t do justice to its greatness. This is animal-print Shakespeare; a sociological excursion into the minds of eccentric Americans who are addicted to the power that comes from owning tigers, AKA big cats. Theirs is a dramatic, intricate hierarchy, and co-directors Eric Goode and Rebecca Chaiklin study its every facet. “Tiger King,” arriving on Netflix today, includes approximately five different true-crime tales (including arson, a disappearance, and an alleged murder plot), and bundles them into one obsession-ready seven-episode series. It’s the kind of story that’s rife for binging as much as extensive conversations about all the bonkers stuff that unfolds.

To top it off, after watching "Tiger King" you can get lost in the YouTube channel of the doc's main focus Joe Exotic, whose original country ditties ("Here Kitty Kitty") are used to accompany many of the miniseries' major developments. Joe Exotic is, in his own words, “A gay, gun-carrying redneck with a mullet,” and is also the owner of the G.W. Zoo in Oklahoma, where he breeds tigers for his zoos or for other owners, to the horror of animal rights activists. Joe is larger than life and fixated on fame, so much that he creates his own reality show about running the zoo. (The show's producer, Rick Kirkham, encapsulates Joe as “a mythical character living out in the middle of Bumf**k, Oklahoma, who owned 1,200 tigers and lions and bears and monkeys and sh*t.”) A lot of the amazing footage that gives “Tiger King” its big laughs and scope comes from Exotic’s consistent documentation—and a lot of these videos have been on YouTube for years.

But “Tiger King” only starts with Joe Exotic. It branches out to his workers, his two husbands, and also zoo-owning peer Bhagavan “Doc” Antle, who exercises his own god complex at his South Carolina Zoo, and believes that there's nothing sexier to people than a tiger. Then there’s Jeff Lowe, who sneaks cubs into Las Vegas penthouses, among other cons. One tiger owner, Mario Tabraue, was the inspiration for Tony Montana in “Scarface,” and talks about his actual crimes in between footage of tending to his big cats. To give you some perspective on the scandalous figures who populate “Tiger King,” Tabraue only appears for a few minutes.

Each player here has a decades-long love of wild animals, an enigmatic presence in front of a camera, and a cadre of dark secrets. Perhaps no one has more than Carole Baskin, whose popular Big Cat Rescue tiger haven down in Florida is aligned with PETA against Joe and other breeders. As you can imagine, Joe hates her as much as he loves his cats, and his bravado knows no censorship when it comes to disparaging her, threatening to kill her, or trying to convince the world that it was Carole who made her missing ex-husband Don disappear. Part of the hilarious madness of “Tiger King” comes from how Joe and Carole’s shared passion is a life sentence, the two constantly clashing, often in the most petty ways, because they have a wildly different approach to the same dream of tiger preservation.

The aesthetics of this story alone—Americana, tiger memorabilia, guns, bizarre facial hair—are a gold mine for a true-crime story, and many other stories would stay at the surface. But “Tiger King” digs deeper, seeking to explore what kind of person would own big cats, or give their life to someone who does. With nary a weak episode, “Tiger King” establishes rich dynamics of possessiveness, of individual kingdoms that can be destroyed from the inside just as much as the outside. This makes everyone's many back-stabbings all the more vivid, especially as Joe later on has to fight for ownership of his zoo, while balancing his political aspirations.

Take episode two, “Cult of Personality,” which focuses on the control that Joe, Doc, and Carole have over the people in their enterprises. Joe has workers who are given miserable living conditions and are fed with expired meat; Don has a cult of women animal trainers that he grooms from a young age; Carole has volunteers who skip Christmas in order to tend to her big cats. Are these leaders providing a sense of direction to their helpers, or taking advantage of them? “Tiger King” has no answers about this, but it gives everyone a chance to comment on the other, and a full picture is painted in the process. Every key player tries to analyze and rat on somebody else, like whenever Joe talks about Carole’s business, his words then reflecting back on himself. Everyone also clings to overdue karma, and thinks that the police didn't do their job regarding the series' multiple baffling, unsolvable crimes.

Seashells Transform Suburban Bathroom Into Tropical Hideaway

A wicker basket filled with seashells and placed on top of a toilet tank has magically transformed Dale and Paula Watson's suburban bathroom into a serene tropical oasis, sources reported Thursday.

"I can't believe the difference adding those seashells made," said Paula Watson, who had somehow been transported from a beige, run-of-the-mill bathroom to an unforgettable island paradise thousands of miles from the Greater Cleveland area. "Every time I walk in here now it's like, 'Wow, where am I? CancĂșn?'"

According to household sources, the extraordinary transformation took place at approximately 10:32 a.m., when Watson neatly arranged a handful of seashells inside a round wicker container and looked up to suddenly find herself at a beachside resort where all the troubles of modern life just melted away.

The magical seashells, which are able to conjure up the cool, tropical breeze of a seaside cabana, were personally gathered by the couple during a recent trip to Myrtle Beach.

"It's like our own little island getaway right at home," said Dale Watson, who stood as if surrounded by palm trees and soft white sand beaches in the spot where there had only been a shower mat and curtain before. "I feel like I should be eating grilled mahimahi right now."

"This is the way life should be," Watson added. "Time just slows down in here." (...)

Although delighted with the transformation, Paula Watson said she had plans to improve the 80 square feet of island paradise by adorning the blissful space with vanilla-scented coconut candles, a ceramic clown-fish figurine, and sand-dollar shaped soaps.

"I love our secluded little vacation destination, but we can always spruce it up a little," Watson said. "It would be neat to get a large glass container and fill it with beach sand, a piece of coral, and more seashells."

"It's like bringing the Pacific Ocean to us!" she added.

Watson also admitted she's had her eye on a nautical-themed light-switch-plate cover featuring a seahorse, which would further transform the tropical hideaway into the magnificent kingdom of Atlantis, a stunning underwater realm where dolphins and mermaids dance and play.

This is not the first time that Watson's home has undergone such an incredible metamorphosis. In 2004, a framed painting of two deer instantly turned the family den into a rustic hunting lodge, while in 2005, the corner of the living room became an old English cottage after a porcelain tea set and a vase with dried flowers were added to an end table.

At press time, the tranquility of the secluded tropical getaway had been shattered when Paula Watson walked in on their 16-year-old son, Christopher, masturbating to an old issue of Good Housekeeping.
