Hospital nearby is full with covid patients according to spouseAnon who works there. We are in the southeast. Make if that what you will.
As far as I know the telltale sign is when you do an X-ray. There’s a ‘frosted glass’ appearance to the lungs. Anon is not dr, but spouse is in medical field and treats them.
Other than that I don’t know any more than you. I just wanted to pass along local info
