I wish other central banks (in other countries) stepped up to this amazing level.
It could end up that members of mostly one party in the Senate end up blocking most of these bare minimum measures.
Look at what some European countries are doing as the minimum: https://www.nytimes.com/2020/03/28/business/nordic-way-econo...
Here are some (for the most part) good ideas that should be considered: https://www.nytimes.com/2020/03/30/opinion/coronavirus-econo...
Why is an 'employment guarantee' any better than what is happening in most of America -- layoffs with an explicit promise to rehire once the business is allowed to operate? It's not like paying companies to keep people on payroll in jobs that are not producing economic value really reduces unemployment anymore than not testing for coronavirus makes it go away.
I don't know why americans are so afraid of 'mass unemployment'. Most businesses will survive this crisis, due to debt suspensions or new debt at a very low rate or via direct government aid (which the government has so far provided plentifully, and will likely do more). Businesses have promised to rehire. However, a business that cannot right now provide a job that has value to the business ought to lay off people and let the social safety net take care.
The articles make some good points regarding healthcare, but aside from that, it makes no good argument why unemployment + the unemployment insurance that workers have paid into for exactly this scenario is worse than paying businesses to keep people on payroll who wouldn't be there otherwise.
In the United States, health insurance is provided by your employer. To purchase it without their leverage is prohibitively expensive without a sizable, reliable income.
Freezing the economy would be paying businesses to pay for overhead and labor. This would ensure everyone's job is frozen in place while furloughed.
What we have instead done is try and form a cocoon like a caterpillar does. If you don't know about how a caterpillar becomes a moth, well it basically just dissolves completely into goop in that cocoon and forms an entire new animal out of that goop. We are allowing the economic structure to dissolve into goop while paying everyone to keep alive while at home inside the cocoon. However, since we've eliminated the structure, what emerges will not look the same. It will be much smaller as capital moved to safer investments. People will not be able to get their old jobs right away, if at all. They might have to change fields. It is going to suck and a lot of people will end up set back in their lives and careers as a result.
"Rehiring" can also be slow because it forces employers HR departments to screen candidates all over again. If employees stay on the payroll, they can all report back to work once the crisis has passed. Instead, businesses that survive have to spend their first weeks "hiring" back employees if they can, instead of making profits. This delay will hurt the recovery further.
> "Rehiring" can also be slow because it forces employers HR departments to screen candidates all over again.
No it doesn't. Just call your old employees and give them a job back.
This isn't going to be unpaused. The economy will be spun back up gradually for everyone's safety. People will likely still be getting sick. Some at-risk people may not be able to safely re-enter the workforce for a long time.
Unless those promises are binding (they aren't), then they're worthless. A lot of people who have been laid off because of coronavirus will discover in the coming months that their job is actually gone, because businesses will be conservative and not rehire as many people as they had prior to entering the throes of the recession. Also, not all businesses will return to employment at the same time, so there's going to be massive turnover as people who were out of a job for awhile change employers and take the first job that becomes available, not necessarily the job that they already had.
And keep in mind, the layoffs Americans are facing now are real. They're losing their benefits, their health insurance, their vacation days. There's a real friction in both firing and hiring someone and we'll be paying it on both sides.
All told we're going to be seeing massive disruption in the US labor market, which would've been avoided had everyone just had a temporary government-paid furlough while maintaining their job and benefits.
Rather than waiting for an infinite time horizon and theoretical rampup, the better approach would be to build a bridge for a bit.
Of course, plenty of companies will not bankrupt, but of those that don't, they aren't going to be expanding their payroll anytime soon after the stock market just took an absolute pummeling and removed years of economic gain in days.
The market is currently being propped up by the federal reserve providing unlimited quantitative easing at the cost of inflation, not a long term solution. Even if we gave everyone a cure and vaccine tomorrow, we are on shaky ground because of what the fed has been doing, for better or worse, and will be in a recession for years.
The approach of firing idled staff and just having them collect unemployment doesn't value the preservation of the employer-employee relationships, and assumes that if they are broken up, they will all re-emerge naturally if necessary after the lockdowns are over. This is a more libertarian approach - no guarantees to employees (but still not totally as it still involves government backed unemployment insurance programs).
Oh I disagree, I think there is plenty. Every politician knows that incumbents are more likely to lose in a down economy. That's why they just passed an unprecedented stimulus bill
You also can't stimulate an economy that's paused.
This bill was stripped down compared to what European countries are providing because of a lot of vocal politicians worrying about creating disincentives to work which is such an unfathomably stupid thing to worry about during a pandemic.
I don’t think there is any model that can predict pent up demand.
I know a lot of my friends who still have jobs are talking about going out every night when the quarantine lifts so they don’t have to cook.
If a lot of people do that, we’ll suddenly need a lot of waiters back. And then they’ll have money.
Or maybe everyone will have learned that they love cooking at home and never go out again.
I don’t think there is any way to tell. We don’t have any good prior data.
All the previous models assumed unemployment claims and stock market drops when it was possible for everyone to work.
Right now there are a lot of jobs that are temporarily suspended skewing the numbers.
Rough times ahead for many, sadly.
I am enjoying spending less money to eat but restaurants will not be able to reduce price to meet the lesser demand because their rents will not go down any time soon. The current restaurants will have to fail and that property will have to sit for potentially years before rent is reduced.
We need a penalty (additional property tax?) on vacant real estate to drive prices back down with shifting demand.
I’m personally aware of several small businesses that are simply burning capital from family or friends to stay alive. Almost all of it goes to rent.
I've really noticed it in our trash and recycling bins. They've been half full on garbage day since the quarantine. Usually we have more than we can put in them. I'm hoping this behavior sticks for us, but I kind of doubt it.
Presumably all of those bill are owed to other businesses, who are run by people. People with empathy. People who realize that keep a good customer is better than losing them, even if it means cutting them a break.
I think people will surprise others with how this pain will spread through the entire supply chain so it does't kill any one business. I think all the businesses in the supply chain know that killing everyone at the end of the chain isn't a good idea.
Are we willing to trust our collective empathy or do we need the social contract to fill in the gaps for collective protection from this harm?
I believe many will benefit from empathy, but it will be disproportionate and many communities who will need it the most will not receive it.
Most of the demand shortfall we're going to experience in the coming months will come from people being out of work, not from their being quarantined. That doesn't create pent up consumption that can unleashed at a later point in time.
By that time every restaurant will have had all its fresh food expire and will need to predict when the demand for it will return. If they do not do this accurately, they risk wasted capital that they'll need for when the demand does come back.
They'll have had to been paying rent or mortgage on the property they currently occupy, with only the revenue they're able to make on take outs.
Depending on the structure, I predict most restaurants won't survive this. Any restaurant with a dining room is toast. The world will look different after the crisis.
The world will look different after the first of the very next month.
Everyone keeps assuming landlords aren't people. If you own a commercial building with say six storefronts, once the SIP lifts, you have two choices:
Demand immediate back rent from all your tenants and then evict them all, leaving a completely empty building, or work with them so they can remain open and at least give you partial rent for a while until they can pay you back.
Yes, the government will need to step in and declare mortgages were on hold and no back payment is necessary, but that's already in the works.
I think landlords are smart enough not to just evict everyone as soon as they can. They know that no one will come and take that spot.
It's better to have partial rent than none at all.
And this is the happy choice! Existing businesses will be saddled with the debt of operating through the crisis. New businesses without that debt will have an advantage.
When bankruptcy is logistically more advantageous than debt service, bankruptcy naturally follows.
The world will look different after the crisis.
They're also very much away of these various factors, but know better than to assume there will be major pent up demand with an economic shock of this nature.
These jobs are not temporarily suspended unless the government intervenes on the scale that European governments are. They will be lost, leaving scars on the economy. No one will be willing to endure this again, when needed again in the future, if they have to sacrifice everything all over again.
What percentage of the U.S. population can actually afford to eat out every night?
Median U.S. household income is about $62K.[1] If you spend only $15 a night eating out, that amounts to $105/week or $5460/year, which is a good chunk of the median household's income, and an even bigger chunk of their income after paying for rent, utilities, taxes and other necessities.
[1] In 2018. Source: https://www.census.gov/library/stories/2019/09/us-median-hou...
So before all this, quite a lot of people dined out a lot.
My guess is that most of those meals are people going out for lunch while they're working, and most of those people are grabbing a sandwich and bringing it back to their desks, which generates no income for waiters.
What you’re saying makes sense only if these lockdowns are very short.
Nice caveat!
It will come down to the collective confidence.
Confidence to lend people money, to employ people, to spend money instead of overpaying on the mortgage to reduce the chance of default.
If there is a recession it will be a self-fulfilling prophecy.
I'm just saying we don't have any prior experience to guess as to how much it will or won't recover.
Well, a totally naive model would be a uniform prior bounded between 0 and 1. The blog post says that they think it'll be between 0.1 and 0.4. That's more narrow than the naive model, but it's still pretty large error bars. I don't think they have spoken with much more certainty than is justified.
But as near as I can tell, we only ever sent about 10% of the population to WWII. This is 3x the hit of WWII! (I get that we don't have to make guns and tanks for people, just feed and house them).
Also, there's only so much the Fed can do, it really is just a bank that deals exclusively with other large players by sending pieces of paper around (or these days - data packets). That's it. The rest is up to the Congress, the Fed has already printed the money for them, and will surely print more if needed.
Ultimately it's a medical emergency, not a financial one. It's up to the doctors and people in charge to help fix this mess. The "money people" are merely dancing to the spectacle.

But yeah right now the US stock market is ridiculously large, you're right.

Fed cares about the credit market, not the stock market. It's amazing how many people don't even know that the credit market is much bigger than the stock market. Since these days everything is an ETF you can look up $LQD (investment grade corporate bonds) and $HYG (low grade/junk corporate bonds) to see "what's really going on". You can also look up spreads for each rating grade on FRED.
Like, independent of whether you think the shutdown is the right risk / reward tradeoff, please at least think about the 70% of the workforce that cannot work from home, because they work in restaurants or physical service jobs. If you are still working (or at least pulling a paycheck), you're incredibly lucky -- please don't act like you have the only voice of moral authority about when and how this should end, and the calculus that goes into that tradeoff.
There is a good chance the lockdowns are saving more lives due to the normal flu then covid.
So, the question really is: at what point is the cure worse than the disease? To answer that, you have to look at the impact of people at the very bottom of the socioeconomic ladder, not professionals who are WFH and largely insulated from it.
I think it's important for us to band together and make sure we can all make it through this stress together and I don't mind if, as someone on just barely in the "haver" side of thing, I need to surrender some of my stuff to make sure those worse off do well.
That all said, I'm up in Canada where I don't gush lovingly over the government, but I find it to be reasonable and well intentioned... And I think the US has a real problem coming up where nearly nobody wants to help the common good because both sides have been constantly fed that the government is terrible and only acts in the interest of big businesses (which, generally, it does).
If you want to get mad, get mad at incompetent politicians who aren't doing enough to ensure a speedy recovery.
Those people out of work are significantly less in trouble if they don't have to pay rent
Landlords are in significantly less trouble if they don't have to pay their mortgages.
That's all you have to do to help out Americans out of work (along with unemployment)
The stimulus bill along with local and state government's are already doing most of this...
One of these things is not like the others.
I don't disagree that we will have to figure out how to make all this works without collecting 100% of mortgages, but the idea that it's so easy is crazy.
It seems as if the HN community feels very strongly that either this should not be questioned or that the only acceptable response is nobody should die from a virus, no matter the cost.
This is not an official St. Louis Fed calculation. The post is titled “back-of-the-envelop estimate of unemployment”, the data sources are from two blog posts, and it was written by a researcher on their blog. This is not an official document, and appears that it likely wasn’t vetted.
> [T]hese calculations do not account for any potential effects of fiscal measures, such as payroll support measures for small businesses
A $2 trillion stimulus very likely means that the actual figures are significantly less than what this model calculates.
It's been turned back on, which is why the market is bullish at the moment.
* The correlated decline in productivity, the gaps in mortgage and rent payments, and so on do not result in our financial system breaking in surprising ways, like how a small increase in mortgage default rates did with synthetic collateralized debt obligations in 2007-2008. An increase in fixed rate mortgage defaults from 5% to 10% contributed significantly to the largest recession in nearly a century. I don't think anyone can say with certainty that nothing like this lurks in our financial system, this is like a bug in a program which requires dozens of different code paths to all enter into an invalid state simultaneously, and only then do you see the result.
* That we can actually restore everything to normal by June with the development of a cheap and easy to administer vaccine, which seems extremely unlikely to materialize in only 2 months.
> like how a small increase in mortgage default rates did with synthetic collateralized debt obligations in 2007-2008.
What you fail to mention is that most mortgages in 07 and 08 were perfectly fine and you could find alternate home owners willing to actually pay. This is completely different. The government has shut down the economy. It's not like there are a lot of people you could sell a home too. Most debt collectors are going to let the debt go and not demand it, realising they cannot find any alternative.
> * That we can actually restore everything to normal by June with the development of a cheap and easy to administer vaccine, which seems extremely unlikely to materialize in only 2 months.
Unlikely that there is a vaccine, but we won't need it. The country has gone through much worse pandemics, and they typically do not cause great economic harm. In fact, they often lead to boom timse.
> Most debt collectors are going to let the debt go and not demand it,
I find it hard to believe you're familiar with debt collection in the United States!
> Unlikely that there is a vaccine, but we won't need it. The country has gone through much worse pandemics,
If we're willing to just let lots of people die, then sure, we "won't need it".
The case fatality rate (CFR) depends on ventilator and ICU capacity. We'll have a better estimate for US case fatality rates due to the outbreak in New York soon, but so far it seems to be that even though deaths lag cases, deaths have been roughly 2% of confirmed cases for a few weeks. If that holds up as confirmed cases rise into the millions, that would put this on par with the 1918 pandemic. If it doesn't, New York will give us a better idea of the CFR in a modern American city's medical system.
which we got through without state-wide lockdowns.
Imagine you're a property owner with a small strip mall. You've got mortgage, taxes, insurance etc that have to be fed by rents. So you tell your renters "Don't worry, I've got your back." You get a zero interest loan from the SBA, and everything is fine. Except your renters have their own rent/mortgage/insurance/taxes to pay. And they need to eat and pay medical bills. But the government only gives you a max of $3400. That lasts you 3 weeks. So this renter gets his own SBA loan, yeah at 0%. All good except he has no customers.
This goes on for 2-3-4 months. Things open up, and the renter tries to restart his business. But now he's burned through his SBA loan. He's burned through his $3400 check, and he's burned through his savings. So he has no capital, except maybe some biz equipment. He can't swing another SBA loan because Congress can't agree for more intervention, so he shuts down. Now he has a debt to the SBA, and "forgiveness" from you. End of the story is that he's out of business, all his employees are fired, and you have an empty slot in your strip mall.
If anything, this 'recession' shows the scary power of the government, and of authoritarianism. With the stroke of a pen, the government of the United States and its states can inflict economic damage worse than any market-based recession. That is truly scary.
Of course, in this case, this temporary suspension is probably worth it, but it is an easy counter argument the next time someone attempts to explain why government economic control would lead to fewer recessions and depressions than the market.
many businesses may send workers home with pay instead of laying them off outright.
Others may get some other benefit, like the friend of a friend who gets health insurance but no pay through the beginning of June. Not sure how it impacts unemployment benefits. I think the hope is that this thing will cycle through, the economy will recover (like after 9/11) and people can be brought back to the same job.
I thought the expert advice from the WHO is to not wear a mask?
> There is no specific evidence to suggest that the wearing of masks by the mass population has any potential benefit. In fact, there's some evidence to suggest the opposite in the misuse of wearing a mask properly or fitting it properly.
Do you know better than the WHO?
It's bewildering the US and European guidance on this.
Edit: read this carefully: https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2843947/ It will apply to SARS-CoV-2
Frankly, you don't need to be 'qualified' to read review articles in this area--I encourage any logical citizen to do so. Specialist articles?...sure, it's unlikely you will gain much from reading those.
Apparently.
The one thing I learned from this pandemic is to distrust scientists at the WHO and the CDC and to read the primary literature directly. These folks are far too involved in politics.
Better "trick" the public then.
Doing this really seem like a much better way to handle the situation than giving a really really dangerous false advice like this.
Obviously there's a need that's not being met, but it's nearly two months since masks became hard to acquire.[0] Can we not change the official recommendation to "make a cotton mask and wear it if you go out for groceries; here's a template. Don't use N95 masks, instead donate them"? It would be great to have numbers on this.
[0] anecdotal, Bay Area.
Looks like mask production has been ramping up since January, at least. But numbers of the big picture would be neat to see. https://www.wired.com/story/surreal-frenzy-inside-us-biggest...
Seems to me that the biggest problem we have is lay people thinking they know better from reading random isolated papers without context and doing their own thing against advice designed to make everyone safer.
Shouldn’t we be going with data rather than ‘common sense’?
Other times that hasn't happened yet and you still need to make a decision about what to do today, not after six months of further study.
As far as I can tell, they are not saying anything about the other much more important aspect of masks protecting others when everyone wears them.
And that's in my opinion very very wrong and is most likely already costing many lives...
They say there is not enough evidence to back up the idea that the general population wearing masks has a benefit to everyone.
> There is no specific evidence to suggest that the wearing of masks by the mass population has any potential benefit.
IIRC the CDC recommended against early on, I don't know about WHO or where CDC stands on it now. But interviews like:
https://www.sciencemag.org/news/2020/03/not-wearing-masks-pr...
from other experts give reasons why it is effective:
Q: What mistakes are other countries making?
A: The big mistake in the U.S. and Europe, in my opinion, is that people aren’t wearing masks. This virus is transmitted by droplets and close contact. Droplets play a very important role—you’ve got to wear a mask, because when you speak, there are always droplets coming out of your mouth. Many people have asymptomatic or presymptomatic infections. If they are wearing face masks, it can prevent droplets that carry the virus from escaping and infecting others."
// end of interview comment.
Could it be that CDC knew knew masks worked, but didn't want people to stockpile them? Or could it be that most people won't wear them effectively? No idea which, or both.
I believe the right thing to do is to ramp up mask production and try to get a very small number per capita (after healthcare workers have sufficient) to the sick and general population, especially around areas like NYC. Then educate people on how to wear them.
I'm not convinced masks help either way.

> Some people with swine flu travelled on a plane from New York to China, and many fellow passengers got infected. Some researchers looked at whether passengers who wore masks throughout the flight stayed healthier. The answer was very much yes. They were able to track down 9 people who got sick on the flight and 32 who didn’t. 0% of the sick passengers wore masks, compared to 47% of the healthy passengers. Another way to look at that is that 0% of mask-wearers got sick, but 35% of non-wearers did.

> ...the vice president of Taiwan, a prominent epidemiologist, gave regular public service announcements... These announcements included when and where to wear a mask, the importance of handwashing, and the danger of hoarding masks to prevent them from becoming unavailable to frontline health workers.

From what I gathered from their guidance the basically say masks are not effective enough to protect you & people do not know how to use them.
Well, the problem is that how well the mask protects you is at this point int time actually a secondary concern. The biggest issue is protecting others from you when you are infected and do not know that yet, which is a very big problem for covid-19 due to many asymptomatic carriers.
Even a piece of cloth covering your mount and nose can reduce the amount of infected droplets you generate be sneezing and breathing significantly if not totally stop transmission barring really close physical contact, so there is really no good reason for everyone not to wear a mask.
That WHO is totally neglecting this aspect of the mask protecting others is almost criminal negligence.
Why give them to nurses and doctors then? It would suffice for the patients to wear them. If they do work at protecting you, then let's say a patient can't wear one, should you wear one? The answer is yes. Therefore the only logical conclusion is that an N95 mask protects you.
There is ample scientific evidence that masks work both to prevent being infected and to prevent infecting others.
The argument seems to be "there is sufficiently low risk from normal daily activities that it's not worth wearing a mask." If that's the case, why can't I leave my house except for groceries? How did all of those people catch this thing if the risk is so low? The reality is that the risk for everyone, given the severity of COVID is high. The risk for healthcare workers is beyond extreme.

Step 1. Avoid old people and just do normal life, build an immunity.
Step 2. Now enough people are immune we can hang out with old people again.
But we are at Step 0 and are making a big delay for steps 1 and 2 which will still need to happen. There’s a big risk the second wave will be more tragic than the first if people don’t realize it.
It's not just old people who are at risk, BTW. With medical treatment the death rate of under-40s is about 0.2%, 30x less than the ~6% of over-65s. However, young people are still hospitalized at roughly half the rate of old people; if the hospital system is overwhelmed we can expect a death rate of ~5% of young people. That's about a 10 million young people in America alone. That's why it's so important to delay the epidemic long enough to build enough hospitals and ventilators to treat everyone.
This is extremely unlikely unfortunately, most flattened curves end up overtaking the populace at large - the more crucial element to control is the proportion of the population that's sick at any given time to avoid overwhelming healthcare or logistic resources.
how is this true?
I know 0, and my self-isolation prevents me from being near anyone who is asymptomatic.
By wearing a n95 mask you are giving doctors the middle finger.
People need to dig around in their garage and get these things out, and then start wearing them. Even the disposable ones can be reused many times, particularly for someone that is just at the grocery store and not intubating COVID patients or something.
I'm sympathetic to the argument that healthcare workers need them, but healthcare workers also need people to wear them so that they don't get sick and show up at the hospital!

The two runs we've done were to the super market & pharmacy (about a week and a half ago) and to my wife's office building since she needed records of employment to let folks start collecting unemployment. At this point a mask is a good idea - but simply not going out is a better one.
I'm only partially joking. For example, McDonald's doesn't allow Halloween masks inside the store to discourage robbery.
Do you think they were ready to stop airplanes and require people to wear mask back then?
Even now the risk of contracting the virus, if you are following isolation protocols, is extremely low.
People who interact with individuals who are sick and need treatment are putting themselves and their families at risk because of you.
This false sense of security erodes basic isolation and sanitary measures which are more protective.
I understand people want to feel safe, its better for them to be safe.
http://www.virology.ws/2018/03/01/influenza-virus-in-the-eye...
By the way, we learned that a century ago during the 1918 Spanish flu pandemic - wearing masks help, even with non-N95 masks. Influenza could also caused by corona viruses, also transmitted via droplets primarily, just like the SARS-CoV-2
However we didnt, so stop promoting ordinary people wearing masks.
[1] Masks protect other people from you spreading the disease if _you_ are sick. This is true, unless you spend your day around covid-19 infected individuals all day long for your job. [2] Doctors and nurses need that mask. They are the ones who spend their day, risking their lives and their families health to treat these people.
Even now the risk of contracting the virus, if you are following isolation protocols, is extremely low.
Masks reduce risk.
> [2] Doctors and nurses need that mask.
Here's the reason, right here.
Seems like we didn't prepare. There should be enough masks for healthcare professionals and ordinary citizens.
Wearing a mask, if the entire population is infected, provides a benefit because you are surrounded by infection. Guess which person spends 8 hours a day in a highly infected population? Doctors, especially in the intensive care unit.
If you were worth as much to humanity as a doctor, as an ordinary person, your logic would save fewer lives. However it would increase your chance of being saved.
Stop lying to people that masks aren't effective. Not only does that put people in immediate danger, it makes it more difficult to walk back that advice in a few months, when we're definitely going to want everyone to wear masks when in public.
Doctors and nurses need that mask
So make your own. Even half of a t-shirt is much better than nothing.
I don't think they'll earn back respect for at least a generation. People won't forget this.
By the time more mask factories are up, the capacity will no longer be needed. Same goes for ventilators. Too little too late; shouldn’t have outsourced manufacturing to China a generation ago.
The better solution is diversification of global supply chains which benefits all countries long-term.
If we just tell (or force with fine) everyone to wear a mask and have their mouth covered whenever in close proximity with some other person, we can go back to usual life. What's so hard about this?
1m27s video -- https://www.cbsnews.com/news/preventing-coronavirus-facemask...
* University of Washington, in Seattle.
Thought experiment: Take a small sip of beet juice and then simulate a sneeze or a cough while standing several feet in front of your clean white wall. Next, take another sip, wrap a handkerchief around your face and then sneeze / cough / spit. See how far that "virus juice" flies when you wear a mask?
If everyone wore a mask, then all the people who are sick are effectively increasing their social distance from the healthy people. Even if the sick person walks within 6 feet of you, their effective social distance might be greater than 6 feet if they are wearing a bandana, t-shirt, surgical mask, etc.
Wearing a face mask works on a population scale. Everyone should be wearing a mask.
This is how it happened here in Czech Republic - one day as part of the emergency measure face masks (including home made ones) have been made mandatory in public, fullstop. Don't wear one & the police will request you to put on one or face a fine.
This we we went from you in public getting weird looks if you have a mask to anyone not wearing a mask getting weird looks in about two days.
Since then the neighboring country of Slovakia to the east adapted the same rules for mask wearing in public and most recently Austria to the south adapted mandatory mask wearing in shops.
A full bio-hazard suit is too expensive and quite impractical, less than that is not safe.
Mandating everyone in airports, on planes, etc.. must be wearing a mask is 100% possible and would have slowed the spread. Don't have a mask? Here's some scissors, cut up a shirt in your luggage and make one.
In Seattle, I'd say around half of the people I've seen in public are wearing masks this week.
