It seems people get less sick if they wear a mask.
When you wear a mask â even a cloth mask â you typically are exposed to a lower dose of the coronavirus than if you didnât.
Both recent experiments in animal models using coronavirus and nearly a hundred years of viral research show that lower viral doses usually means less severe disease.
No mask is perfect, and wearing one might not prevent you from getting infected.
But it might be the difference between a case of Covid-19 that sends you to the hospital and a case so mild you donât even realize youâre infected.
A surgical or cloth mask canât block out 100% of the virus, but it can reduce how much you inhale.
The goal of any tool to fight this pandemic is to slow the spread of the virus and save lives. »
