This is a good example of how easy it is to misjudge risk.
When you go to the US, you’re not really going to the US as far as national COVID numbers are concerned. You’re going to a specific place. You should look at the trends in that place compared to the place you’re in.
The positive test rate in NYC is under 2% now and there are only 405 cases/day average in a city that’s nearly as big population wise as all of Taiwan. 85% of the people in NYC have received at least 1 vaccine dose and 86% of those who have received the vax are fully vaxxed.
Coronavirus in on the run in many places in the US. It’s just getting started in TW.
When judging the risk, I think you have to look at the case trends, vaccination and immunity rates, hospital utilization rates, vaccine availability, etc.
