For months it has been clear that wearing a face mask reduces the transmission of Covid-19, because it prevents your respiratory droplets from spreading and potentially infecting other people.
Wearing a mask is "a two-way street," Dr. Anthony Fauci told MSNBC's Andrea Mitchell in an interview Tuesday, citing new research on personal protection from mask-wearing.
Some data has shown that a multi-layer cloth mask made from a fabric with a high thread could filter out nearly 50% of respiratory droplets and aerosolized particles.
The CDC currently recommends that people choose masks that are made from two layers of breathable, washable and tightly woven fabric.
The CDC says that a combination of "universal masking policies," social distancing, ventilation and hand hygiene could prevent future lockdowns.
