To wear a mask or not? Experts answer coronavirus protection questions

LA Times  

A man wears a mask as a precaution against catching the coronavirus as he rides his bike on the Mission Beach Boardwalk in San Diego. Although surgical and homemade masks don’t filter out particles as effectively as N95 masks, Chi said they can still be useful. Surgical masks cannot filter out virus particles, but they can protect the wearer from droplets coming out of a sick person’s mouth when they cough, sneeze or talk, Chi said. Chi said that people working closely with COVID-19 patients need to wear N95 masks to protect themselves from the virus. However, average clinicians not working so closely with people who have known infections could use surgical masks or even homemade masks.
