Yes! The surgical masks MIGHT filter out droplets that got the virus.
Those droplets will likely be breathed in from side of the masks and bottom of masks.
Even if not that case, those droplets stay on the mask.
And dry up in maybe 5 to 10 minutes.
Remember the virus will still be alive after many hours and days even when on door knobs and railings and buttons.
You think they die immediately on your mask fibres? Or remain alive.
And the live virus now on your mask fibres.
And when you inhale, the air rushing past the fibres will pick up the virus into your nose and lungs.
Besterest way to stay safe is to
paste a yellow fu on your forehead that cover you down to your lips.
If you kiasu, stick two of them.
