What does PMs mean?

Also it doesn't make sense to me that "we should leave masks for doctors", as experts and media are saying. The masks sold in the grocery stores and pharmacies are surgical masks.

Surgical masks prevent the wearer from spreading the virus...

Doctors and nurses should have N95 masks, which prevent the wearer from obtaining the virus...

I agree something is better than nothing, but if doctors and nurses are treating infected patients, surgical masks do nothing for them!

In an ideal world, IMHO - we common folks wear surgical masks to contain the spread. Hospital staff wear N95 to prevent them from getting sick.

The sooner we realize this fact - the sooner we can massively produce masks and get people to wear them when going out.
