It says you need to test negative 3 days before flying, so you would not be able to fly on shorter notice.
First, a "clicky": https://www.usatoday.com/story/travel/airline-news/2021/01/12/covid-test-required-international-passengers-flying-into-us/6640424002/
Wonder if that is WITHIN 3 days, rather than 3 days prior to flight? That would make more sense.
Tbh, none of it makes a ton of sense. The rapid tests are highly unreliable, to the point that they tell you to take a reguler test if you get a positive covid 19 result. The other test takes a day or two to process. And you can get covid after you take the tests. Unfortunately, people dont stay home when they are supost to, if they did that we wouldn't need to be regulated to death by these rules. Will it help, maybe. In that it will discourage sick people. So it may help a bit.
No tests aren't 100% but they don't need to be 100% to significantly reduce the number of infected individuals entering the country.
Let's say the test is only 80% accurate and 5% of the local population is catching it per 3 day period. That would mean roughly 75% of cases are caught before they get on the airplane. Reality is 5% is not catching it every 3 days or we would have hit herd immunity a few months back. You can play with the exact percentages but it will slow transmission across borders.
Keep in mind, for most countries, there are already home grown transmission so the idea is to slow it down, not stop every last case.
It's only isolated countries (typically islands) that have no cases where an attempt to hit 100% exclusion is useful.
