Do face masks prevent the spread of COVID-19?


Yes, face masks are effective at preventing the spread of COVID-19. The virus that causes COVID-19, known as SARS-CoV-2, primarily spreads through respiratory droplets that are produced when an infected person talks, coughs, or sneezes. Face masks can help to prevent the spread of these respiratory droplets and reduce the risk of transmission.

Multiple studies have shown that wearing a face mask can significantly reduce the spread of respiratory droplets and aerosols, which can carry the virus that causes COVID-19. In addition, face masks can help to protect the wearer by reducing the amount of virus that is inhaled.

The Centers for Disease Control and Prevention (CDC) and the World Health Organization (WHO) both recommend the use of face masks as a key strategy for preventing the spread of COVID-19. It is important to wear a mask correctly, covering both the nose and mouth, and to use other preventative measures, such as social distancing and hand hygiene, to reduce the risk of transmission.
