I'd say Americans won't be allowed to travel to any country for the longest time.
A lot of Americans still believe one or more of the following: that masks don't work, that the tests are turning in false positives, that hospitals are faking the high incident rates, that it's all a hoax by the democrats to get Trump out of the office. They insist that living in the Land of Free, Home of the Brave means they have freedom not to wear a mask and courage to face down the virus.
Travel outside the country? I don't even know when I can eat outside my house!
That's really more bad news. Wonder how they explain the virus in other countries? Sorry, I know it's really sad. Please stay safe. Hope the internet will give you the chance for some social not-distancing.
