Actually, in a report I saw, the WHO rejected one study from China - saying up to 40% of transmissions were from asymptomatic - as unreliable. They then cite two studies of about 90 people each. One found ZERO transmission from asymptomatic, and the other found ONE. So...one possible out of over 180 total, thus transmission via asymptomatic people is rare.
That is from their report on wearing masks, which essentially says masks are worthless outside of a hospital environment.
You can do what ever want, your life. I do not trust W.H.O.
