Do you think places like California had this virus way back to months like December and how would be go about testing for that. My own sister in March had many of the symptoms including fever and chest issues but they said she had Mono and didn't do a test and than later said she also had RSV. My family thinks she had the virus but is that really possibly?
I labeled this wrong it is for today's class on the 27th
Probably not in December but certainly in March. The only way your sister could be tested now is with the antibody test which is not readily available.
