BREAKING—US has added South Africa 🇿🇦 to list of restricted travel countries because of the new #B1351 variant. Also, all “international travelers to US must provide proof of a negative test within 3 days of travel to airlines prior to departure." #COVID19
2) IMHO as an epidemiologist, a test 3 days prior to travel (plus 8-16 hours of international travel time itself) alone is not in any way fool proof. We know one can test negative for 4-6 days after exposure before either symptoms or positive test. Many Trump WH staffers did so.
3) We also need rapid testing upon boarding and testing upon arrival. While not foolproof either, it adds another layer to Swiss Cheese model.

4) We also need to add quarantine requirements upon arrival - of 7-14 days. Shorter if one can test out of it with rapid daily tests. But otherwise minimum 10 days.
Even Australia requires 14 days quarantine for tennis 🎾 players arriving from New Zealand 🇳🇿! Let that sink in!
