CDC recently said, “The United States is moving to require all air travellers entering the country to show a negative COVID-19 test performed within one day of departure.” The new one-day testing requirement would apply to US citizens as well as foreign nationals. The CDC lists about 80 foreign destinations as having “Level Four”, its highest level of COVID-19 transmission, and discourages Americans from travelling to those destinations.
