I thought with this virus you can be be infected but not show symptoms for many days? Hence when HHS sent untrained staff with zero protection to meet all the infected people and then they returned all over the country afterwards on commercial flights, they essentially screwed the entire USA in one easy step, practically malicious idiocrasy.

It's a numbers game. A tool doesn't have to catch everyone for it to help.

Earlier quoted context omitted.

People hear this statement and think it means that anyone that is exposed and catches the virus is able to infect anyone else, just the same as if they were completely symptomatic. But it doesn't mean it is as likely. People with symptoms are more contagious, people without symptoms are less contagious. One simple reason why is that people without symptoms tend to cough and sneeze less.

You don't touch surfaces, trays, etc. at airports? When was the last time you think they sanitized anything at TSA?

Touching a virus doesn't guarantee you being infected. It can't penetrate skin. Inhaling a droplet of saliva that somebody coughed up is much worse.

I’m thoroughly confused. Why isn’t details of airport screening mechanics available? IIRC with SARS thermal cameras were used to screen passengers with a fever. I expect some technical details to be shared without me having to read a bunch of code (with a high probability of misunderstanding something).

This is just a tool used to explore the data. There's a link to the actual screening paper at the top of the page (https://www.eurosurveillance.org/content/10.2807/1560-7917.E...), which cites the sensitivity exit/entry scanners of infrared thermal image scanners at 86% from https://journals.plos.org/plosone/article?id=10.1371/journal...

The tl;dr: Health security theater catches about half of cases. Wouldn't the prudent step be to globally announce a two-week quarantine of all arriving passengers? In other words, not a total shutdown but slowing to prevent spread rather than foolishly squeeze out some short-term, imaginary economic gains. It may not be at all popular, but it would be the moral and ethical thing to do.

It’s easy to sit in an armchair and claim you’ve found the moral and ethical solution, but there are moral, ethical, and logistical ramifications to instituting a two-week quarantine on all overseas travelers including loss of life . Are you also going to quarantine every pilot and flight attendant for two weeks each time they land, given their close proximity to possibly infected passengers? What is the point of a q…

This sounds like moralizing to me.

>including loss of life

How would temporarily not issuing tourist visas kill people?
