> - how useful are those surgical masks for preventing getting sick / infecting others?
After SARS the CDC published updated guidance on masks in relation to Influenza in general. TL;DR is use regular paper masks for general population, hospital staff, and patients. N95 masks for staff doing intake and direct treatment. This addresses the primary problem with N95 masks: hospitals running out.
The "N95" rating means it filters 95% of particles 3 microns or larger. Research showed only Influenza particles 4 microns or larger carried enough RNA to replicate successfully.
