How well do face masks protect against coronavirus?
Content
Can face masks help slow the spread of the coronavirus (SARS-CoV-2) that causes COVID-19? Yes. Face masks combined with other preventive measures, such as getting vaccinated, frequent hand-washing and physical distancing, can help slow the spread of the virus.
The U.S. Centers for Disease Control and Prevention (CDC) recommends fabric masks for the general public. People who haven�t been fully vaccinated should continue to wear face masks in indoor public places and outdoors where there is a high risk of COVID-19 transmission, such as crowded events or large gatherings. The CDC says that N95 masks should be reserved for health care providers.
The World Health Organization (WHO) recommends medical masks for health care workers as well as for anyone who has or may have COVID-19 or who is caring for someone who has or may have COVID-19.
