These are some of the things we’ve learned: Masks and face coverings can prevent the wearer from transmitting the COVID-19 virus to others and may provide some protection to the wearer. Multiple studies have shown that face coverings can contain droplets expelled from the wearer, which are responsible for the majority of transmission of the ...

As recently as early February, the World Health Organization stated that viral transmission from asymptomatic peoplewas likely “rare,” based on information available at the time. But a growing body of data now suggests that a significant number of infected people who don’t have symptoms can still transmit the virus to others. A CDC reportissued Mar...
While research on the effectiveness of universal mask wearing for reducing respiratory droplet transmission is still thin, there is evidenceto support it. Research on SARS, another coronavirus, found that N95 masks were highly effective at blocking transmission of that virus. Even ill-fitting medical face masks have been found to interruptairborne ...
The surgical masks that doctors and nurses typically wear are designed for one-time use, while cloth masks used by the general public would likely be washed, which raises another concern. A studyfrom Nepal on cloth masks designed to protect wearers from larger particles, such as pollution or pollen, found that washing and drying practices deteriora...
As an obstetrician-gynecologist and researcher, I believe that some protection for the public is better than none. A recent article in the medical journal The Lancet Respiratory Medicinestates a similar rationale. The universal use of mouth and nose covering with masks is a low-risk intervention that can only assist in reducing the spread of this t...

Jun 21, 2020 · Researchers emphasize there are two main reasons to wear masks. There's some evidence of protection for the wearer, but the stronger evidence is that masks protect others from catching an...
Nov 4, 2023 · For people at high risk, the CDC suggests you wear a mask that provides you with the most protection possible. Wear a mask while in public indoor spaces when your area has a high number of people with COVID-19 in the hospital. Check with your doctor to talk about when to wear a mask at other times.
Jan 11, 2024 · Updated on January 11, 2024. Face masks provide protection against transmission of respiratory viruses. Additional steps to help the spread of respiratory viruses include hand washing, respiratory etiquette, and avoiding others when you are sick. Lisa Maragakis, M.D., M.P.H., an expert in infection prevention, answers questions about face masks.
Face masks help reduce the transmission of SARS-CoV-2 by interfering with the spread of virus-laden droplets ejected from the nose and mouth. Recommendations on the use of masks have varied over the course of the pandemic, depending on available data on the virus 's transmission.
