Face mask：Sick, but no symptoms
As recently as early February, the World Health Organization explained that viral transmission from asymptomatic folks was likely “unusual”. Based on details readily available at the time.

Even ill-appropriate medical deals with face masks have been found to interrupt airborne contaminants. And malware, retaining them from hitting as far when a person sneezes.
