What John is proposing is that after new infections mostly die down, we can smartly relax the restrictions with a bit of common sense without causing rho to go above one ...... Imminently sensible but the world seems to be full of two types of people these days.

'We produce them when we talk loudly or breathe heavily. People around us inhale them and that’s how the virus spreads. We’re beginning to see this risk now.' ...<br /><br />But 20 minutes after the cough, the microdroplets were still floating in the air – and had spread through the entire room.<br /><br />However, when a window was opened, the microdroplets were quickly swept away in the breeze. Any airflow, it seems, will get rid of the super-light particles."realisthttps://www.blogger.com/profile/15859878286157071663noreply@blogger.comtag:blogger.com,1999:blog-582368152716771238.post-77284333920338194292020-04-15T06:42:27.163-05:002020-04-15T06:42:27.163-05:00Professor Cochrane mentions "social pressure&...Professor Cochrane mentions "social pressure". Workplaces won't be 100% in enforcing this norm, but a few people emphasizing it in every office (and at every construction worksite, etc.) can do a lot, especially if the boss gets on board.<br /><br />For places with more structured workstations - such as a factory - it can mean changing how a line is set up to put people more than 6 feet apart. That probably does imply some hit to productivity, but it's more productive than having the factory closed.realisthttps://www.blogger.com/profile/15859878286157071663noreply@blogger.comtag:blogger.com,1999:blog-582368152716771238.post-77099231932852911592020-04-15T06:38:42.696-05:002020-04-15T06:38:42.696-05:00"A homemade mask will be rather less effectiv..."A homemade mask will be rather less effective than a surgical mask"<br /><br />It doesn't need to be 100% effective. The point is to reduce droplet production when a person talks, sneezes, or coughs and combine that with trying to stay 6 feet apart. Almost certainly doesn't *stop* spread, but it reduces it. There's a view that microdroplets expelled when talking are a big issue, and that masks greatly reduce them - https://www.weforum.org/agenda/2020/04/coronavirus-microdroplets-talking-breathing-spread-covid-19/ . I'd think that also indicates that covering the mouth well is more important a perfect fit around the nose.<br /><br />As of yesterday, the city in which I live (Austin) has a general requirement to wear something covering nose and mouth when in public places around other people. I went to the grocery store today, and a substantial majority of people were doing so. Not 100%, but those not doing so stood out. Masks of various sorts - not sure how many were homemade - and a lot of bandanas. I personally have repurposed a balaclava to cover my nose and mouth. Tying a scarf around nose and mouth is probably better than nothing.<br /><br />As for lines outside grocery stores - they aren't ideal, but any store that has a parking lot should have the space for people to remain several feet apart while standing in line. Many stores - including the one I was at today - have marks on the ground for just that purpose.<br /><br />I agree that NYC has some very tough to solve problems of density, relatively smaller stores, and degree to which people rely on public transportation. It's also an outlier within the U.S. on all of those points.realisthttps://www.blogger.com/profile/15859878286157071663noreply@blogger.comtag:blogger.com,1999:blog-582368152716771238.post-16489994866175210732020-04-15T06:18:11.460-05:002020-04-15T06:18:11.460-05:00"In Canada, grocery stores have sanitizer, ca..."In Canada, grocery stores have sanitizer, carts are disinfected before each customer, everybody keep 2 meters away, cashiers are protected by shields and bizarrely there is no riot."<br /><br />That's all also true at the grocery store that I go to in the U.S.realisthttps://www.blogger.com/profile/15859878286157071663noreply@blogger.comtag:blogger.com,1999:blog-582368152716771238.post-27777611889571257852020-04-15T02:33:38.444-05:002020-04-15T02:33:38.444-05:00He is referring to state parks in CA.

Good luck with that. Wher..."Wear masks."<br /><br />Good luck with that. Where would one get, say, a surgical mask? In my area some folks have them but most who do seem to be East Asian; possibly they had their fall/winter stock in hand by October or November, well before this became a general issue.<br /><br />A homemade mask will be rather less effective than a surgical mask, and to be somewhat effective really needs to be assembled with some simple sewing tools/supplies in order to fit semi-properly, especially around the nose. But nowadays lots of people don't have that sort of kit lying around -- it's not 1960 any more. And the places where they could quickly buy some (without running headlong into Amazon embargoes, lengthy shipping delays, and the like) are closed up tight as "nonessential". Catch-22.<br />---<br />With respect to grocery stores: where I am it depends on seemingly random factors. But in places like NYC population is so dense that the problem is essentially unsolvable. Some grocery chains and/or localities aggravate the problem by shortening store hours, clustering shoppers temporally. Then some will impose "one in one out", which leads to huge lines -- and in turn vastly increases the duration of the relevant interpersonal contacts, from hundreds of milliseconds to hours (it seems likely that transmission is affected by cumulative dose.)<br />---<br />And yes, public transportation is a cauldron of germs. When I finally had a car after student days, I had 1/3 or 1/4 as many colds as before. It seems highly likely that something similar would hold for the coronavirus.<br /><br />I have little doubt that transit and overcrowding were key factors in the virus initially exploding silently in NYC. The buses and subways are normally ridiculously overcrowded, so contact with others is much more extensive, close, and sometimes even lengthy, than attending a game at a stadium. (So much for environmentalists who seek to cram and jam everyone into places like NYC in order that wild animals should have vast spaces to roam free.)<br />PaulSnoreply@blogger.comtag:blogger.com,1999:blog-582368152716771238.post-78781757993308316852020-04-14T08:32:16.438-05:002020-04-14T08:32:16.438-05:00Thank you for giving an old man ( 80 y.o.on 6/4/20...Thank you for giving an old man ( 80 y.o.on 6/4/20 ) a space to put out there his observations.
