Use of Face Masks to Reduce COVID-19 Transmission

Using face masks is a COVID-19 control strategy intended to reduce transmission by filtering respiratory particles. Its effectiveness varies with mask type and correct, consistent use, while community-wide effects also depend on compliance. Masking can be evaluated through filtration studies, transmission case studies, and compartmental models and can be combined with physical distancing, sanitation, and personal hygiene.
