Exactly - requiring a negative PCR test to exit isolation (if you got sick there or tested positive on the exit test for return to the US) is still problematic - but this is a big step in the right direction!Now all they have to do is to change the exit requirement from infection and isolation to a negative antigen test or set number of days after initial diagnosis or absence of symptoms. A PCR test can be positive for weeks to months after initial infection, even though the patient can be recovered and non infectious. More clarity needed on PCR testing for release from isolation.
