My husbands business is due to be shut down/rebuilt in July. He will be home 4 months. We are counting the days.
My son who does contract work at a hospital has been working in a covid ward for 2 months now, and no symptoms. I bet he is one who has had it and was asymptomatic. He does wear tyvek/respirator now, but hes not careful so Im sure hes been exposed.
Just make sure your son is topped up on D3.
That’s the best defense right now.
You’ve got until about mid Oct for him to get it naturally. Supplements after that.
