Researchers have suggested that universal mask-wearing might be helping to reduce the severity of coronavirus.

But how much do you know about face masks and #Covid19 immunity?

Test your knowledge with this *thread*!

Face masks can give people #Covid19 immunity

It's true!

Academics argue universal mask-wearing could become a form of variolation (inoculation) that would generate immunity and “thereby slow the spread of the virus”

Wearing a mask can reduce the severity of the virus

True!

It comes as increasing evidence suggests that the amount of virus someone is exposed to at the start of infection - the “infectious dose” - may determine the severity of their illness

Wearing a mask can increase the chance of being asymptomatic

And this is also true!

Wearing a mask could reduce the infectious dose that the wearer is exposed to and, subsequently, the impact of the disease.

Population-wide mask-wearing might ensure that a higher proportion of #Covid19 infections are asymptomatic
