Is a second covid test needed?

Covid testing: Covid tests should be done a) 4 days after you have been exposed to a person who has tested positive for Covid-19 b) if you will be traveling and the airline or destination requires it, or c) if you have symptoms and need to differentiate between a cold/flu and Covid-19. Most Testing locations require a Dr referral. These can be obtained via telemedicine consult or in person consult.
