We now know from recent studies that a significant portion of individuals with coronavirus lack symptoms (asymptomatic) and that even those who eventually develop symptoms (pre-symptomatic) can transmit the virus to others before showing symptoms, the CDC mask guidance says. In light of this new evidence, CDC recommends wearing cloth face coverings in public settings where other social distancing measures are difficult to maintain.
Try again.
Now you switch to the stupid CDC guidelines.. which are wrong.. and contract their own recommendations prior to this situation.
Anyway.. the whole Asymptomatic spreading thing is bunk. so.. get off of it.
I will see your CDC and raise you an NIH.
