Perhaps they made a mistake. It would seem to me if he had it he would show some symptoms. It makes no sense to me. Like when some get killed in a traffic accident and gets reported the person died of the virus and not the accident.
He’s 95 by the way. And many people ARE asymptomatic. This virus is simply not even as bad as the flu, unless you are old and/or infirm.
Average people should not even concern themselves with it. My wife and I don’t. We treat it like the bird flu, swine flu, etc. A non-event.
The lockdown and masks, OTOH, are a royal pain.
