Facemasks <> laptops, but still a virus I supppose.
If you mean "disposable face masks are not clinical-grade protection" then you are correct. If you mean "disposable facemasks cannot reduce the threat from people frothing at the mouth spewing their germs along with their bile" then you are wrong. Anything that reduces the amount of virus being spread by the infected breathing over everything around them helps.
How many times does it need to be said before it sinks in - you do not wear a facemask to stop you catching Covid-19. You wear the facemask to reduce the risk of you spreading it to those around you.
