TK, seriously, where do you think all of these extra patients are coming from. These hospital workers have been there for years and see relatively close to the same numbers all the time. Then there is a story of a new virus, and a couple months later more and more people start showing up with the exact same issues that the virus causes. It's not hard to connect the dots. These doctors are living it all day every day. You think they need a test to know? Sure it's possible they could be wrong here and there, one way or the other. But for the most part, they know who has it by now. The down right stupidity is amazing.
