Do cloth masks protect against viruses such as COVID-19?

Cloth masks do not give the wearer full protection against viruses in the air, but they can help protect others by barricading biological aerosols or "droplets" containing the virus.

This is especially effective in cases where asymptomatic people (infected people who show no symptoms) may be releasing the virus without knowing it.

A Cambridge University study from 2013 found that homemade cloth masks significantly reduced the potential amount of infectious droplets expelled by the wearer.

While cloth masks aren't perfect, they go a long way in "flattening the curve" during a pandemic and are far better than zero protection.
