Can masks protect against coronavirus?

Before choosing the right mask, we need to know whether it can help protect against coronavirus.


First of all, how does coronavirus spread?



Its main route of transmission is droplet transmission. When the infected person sneezes or coughs, saliva will erupt from the mouth, and the coronavirus will attach to these droplets. These droplets may fall on tables, doorknobs, escalators and other objects. If someone touches these places and touches his eyes, nose and mouth at the same time, he is likely to be infected.


So how do masks protect against coronavirus?

It resists from the following two aspects:


  • If you're an infected person, or if you don't know you're already infected. (it's very possible, because many of the people infected with coronavirus are asymptomatic. He doesn't have fever, chest tightness and other diseases, so he doesn't know that he has been infected.)

Wearing a mask can prevent saliva splashing when you cough or sneeze, which largely blocks its spread.


  • If you are healthy, the mask can prevent other people's droplets from falling into your nose or mouth. At the same time, its biggest function is to prevent you from unconsciously touching your face, and prevent the virus that may be left on your hand from entering your mouth or nose.

(statistics show that every 4 minutes on average, people unconsciously touch their faces.)


In conclusion, wearing a mask is an effective way to resist coronavirus before there is no vaccine.
