So after the UK variant is already in at least 8 states, and variants from South Africa, Japan, and other places are racing around the globe, the CDC is going to start requiring covid tests for international air travellers. Yep, these same tests in the news lately for high false negative rates. They've finally decided the barn door should be shut, but it's stuck due the demands of the jet set, so they've got it partially ajar now. Good luck with that.
