Yes he is a doctor and has dealt with this disease. He should have known. Absolutely. Just saying that he probably did not pass it to anyone. It was wrong to take the chance.
My furst thought was to give him the benefit of the doubt. The more I read the more I wonder if he deserves that benefit.
I have to wonder. He has a fiance.....did they kiss, have sex? If so, she needs to be quarantined.
