Surgical face masks can help shield large germ-containing droplets, like spit, from infecting people close by, but aren't much use if worn by healthy people.

  • As the novel coronavirus spreads through the US, people have clamored for now sold-out or up-charged masks of all types in an effort to protect themselves.

  • Here's a breakdown of all the different types of face masks, and who should - and shouldn't - be wearing them.

Since the coronavirus outbreak began in China late last year, face masks have gone from something you see on your dental hygienist to a sold-out commodity in high demand, despite warnings from high-ranking health officials that the masks could do more harm than good when worn by healthy people.

According to the the Centers for Disease Control and Prevention (CDC), people who are sick with COVID-19 and around other people, home caregivers of patients who cannot wear a mask, and healthcare workers treating coronavirus patients can all benefit from masks.

Not all masks are created equal, though: facemasks like the N95 help contain virus particles from people with symptoms who must go out in public, while more expensive full-face respirators should be reserved for people who have trouble breathing in regular masks, or healthcare workers whose facial hair prevents an N95 mask from sealing correctly

Here's the breakdown of which conditions each mask is designed for, and who really needs to wear one:
