I mean, the evidence that I'm aware of as of today is that close to 40 % of the cases of the infections are asymptomatic and asymptomatic people transmit the infection, so, not testing -- I mean, if you have been in contact with somebody for a few minutes, that's okay. But if you have been in contact for 50 minutes and that people doesn't have a mask, I think you need to be tested regardless if you have symptoms or not. We know especially young people going into White House and then transmit inside the household. So, the guidelines baffle me and I really don't understand them.
