All current evidence is that masks have a minor effect, measured in tiny fractions of a percent. https://vinayprasadmdmph.substack.com/p/do-masks-reduce-risk ... To date, I'm aware of no study that has quantified a difference in infection, hospitalization or death that is attributable to travel bans.
> To date, I'm aware of no study that has quantified a difference in infection, hospitalization or death that is attributable to travel bans. Why would you need a study to tell you that if nobody with covid travels to a country, that country remains covid-free? Perhaps you are unaware, but there are countries on this planet that covid hasn't gotten to, and those countries have travel bans.
Like, because of an experiment done on Wednesday, a piece of meat kept carefully covered with metal is not going to sprout maggots and flies. Because maggots and flies are caused by flies laying eggs. That same piece of knowledge can then be used to predict with decent certainty that you’re still not going to sprout maggots and flies if you cover it with glass instead of metal and do it on a Tuesday.
Germ theory of diseases says if you quarantine travel, you can prevent (or reduce probability of) novel COVID diseases sprouting up in your country. Because the disease is caused by germs carried by infected people during the few weeks they’re contagious. You don’t need an exact study to prove that, although it’d certainly be nice.
Seriously. Empiricism is great. Using a kind of mindless empiricism (“models don’t tell you anything, so unless every situation is measured, you have no idea”) to throw doubt on science is not.
