I find it funny how some countries suddenly make your life a lot easier if you have a positive test history. Canada has a fairly annoying requirement to have a negative PCR test taken within 72h of takeoff (or arrival by car), which can be dicey/expensive in many parts of the world to get, but if you have a positive PCR result from 14-180 days, this requirement drops and travel gets a lot easier than those that never…

Why is that surprising? Recovering from a natural infection is more durable immunity than that of the vaccines. Even more so if you have both.

I wouldn’t call it more durable, but it can be more diverse/flexible (there’s more to covid-19 than a specific spike sequence).

But if it was more durable (long-lasting), they wouldn’t have the 180d limit. They put that limit in because of the (lowwwww) risk of continuing to test positive after recovery, but the worst case report I’ve seen is in the 6 week after recovery range.

It’s mostly Canada trying to be punitive when it comes to travelling by requiring PCR, when a within-24h antigen test would be cheap, easy, catch as many asymptomatic cases as a less-fresh PCR, and near zero-risk of false positives immediately after recovery.

A rapid or PCR test from within the last calendar day is required to enter the USA. It's pretty hard to get that in many countries now b/c the winter/omicron surge. Plus, it's often expensive.

I think the OPs frustration and what I've heard from Canadians is that the PCR is harder to come by and Canada doesn't accept rapid tests.

Edit: Also, the cost is much higher. In Mexico I paid $25 for an antigen test. The PCR test cost $100.

“Continue working”… he’s an international tennis star that probably doesn’t need to work an extra day in his life, not a mother of 4 working 12 hours days to make ends meet. Also his only loss would be losing the opportunity to win another Australian Open. But I guess superstars don’t have to make sacrifices like us regular people have had to throughout the pandemic.

he's world #1... you have to work incredibly hard to achieve that (and maintain it)

Good for Serbia for implementing some centralized system. A PCR test result in the U.S has absolutely no way of being verified, either negative or positive

In Israel, which swabs every person who lands at the airport. There is a suspiciously steady stream of people flying in from the U.S who were negative before take off and positive 10 minutes after landing

USA only requires that for air passengers. Requiring overseas checkin agents to be disease doctors was okay, but asking CBP to verify paperwork and stop threats at the border was too much to ask.

This is because Mucosal immunity.

PCR tests can come back positive for several months post-infection, so there may be no point in testing people in that post-infection period, because it will come back with too many false positives to be useful. 180 days sounds long for that, but people do test positive for months sometimes.

The reason you can test positive for so long is that it takes time for remnant RNA from the virus to totally leave your system, and even though it's not replicating (you aren't infected or infectious), the PCR test is just detecting the RNA.
