Wearing a face mask drastically reduces the risk of getting sick with the new coronavirus, scientists discovered.
A team at the University of California Davis Children’s Hospital found that covering the nose and mouth reduced the risk of COVID-19 infection by 65 percent.
Previously, researchers believed that wearing a mask was beneficial only to prevent transmission of the virus to others.
But, as more studies have shown, the piece of fabric not only prevents a sick person from spreading the virus, but also protects healthy people from getting sick
Wearing a face mask reduces the risk of coronavirus by 65%, and social distance reduces the risk by 90%, researchers find. Pictured: A woman wearing a mask and carrying her dog in a carrying bag poses as New York City enters Phase 3 of reopening on July 7, New York City
There are two main methods of transmission of coronavirus, one is through airborne droplets when a person coughs or sneezes and the other through aerosol particles that people spray into the air when we speak.

“Everyone should wear a mask,” said Dr. Dean Blumberg, chief of childhood infectious diseases at UC Davis Children’s Hospital, on July 2 livestream.
People who say, “I don’t believe masks work,” ignore scientific evidence. It is not a belief system. It’s like saying, “I don’t believe in gravity.”
There are two main methods by which the coronavirus spreads, the first through droplets released into the air when someone coughs or sneezes.
Researchers say these drops are about a third the size of a human hair, but visible to the naked eye.
The second way is from aerosol particles that people spray into the air when we speak, which are one-hundredth the size of a human hair and almost impossible to see.
This method is more dangerous in terms of transmission, but can be reduced by avoiding crowded interior spaces.
Studies under laboratory conditions now show that the aerosolized virus survives with a half-life on the hour scale. It lingers in the air, “said Dr. William Ristenpart, professor of chemical engineering at UC Davis.
‘That’s why you want to be outdoors for social situations, if possible. The good airflow spreads the virus. If you’re indoors, consider opening the windows. You want as much fresh air as possible. ‘
Different reports have shown that different types of masks can prevent droplets from entering the airways.
a study discovered that droplets between 20 and 500 micrometers emitted by someone were blocked when the mouth was covered by a washcloth.
Another showed that wearing a mask reduced the amount of drops and aerosol particles in someone with the flu or a cold in the air.
While plexiglass protects face shields and cubicles, transmission can still occur if there is no proper airflow, Ristenpart said.
“The way to think about that is to think about scents. If the person on the other side of a cell or plexiglass wears perfume, you will eventually smell it. he said in the live stream.
The aerosol particles are small enough to travel through the air, just like aromas. That’s why the airflow is so important along with other actions like wearing masks and social distance. ‘
The team says that following mask mandates and social distance will help control the pandemic.
“So we don’t know who could spread it,” Blumberg said.
“We know that social distancing reduces the risk of transmitting the virus by 90 percent, and wearing masks reduces the risk by 65 percent.
“Wearing a mask affects everyone,” he said. “If you care about your family or friends, or care about your community, wear a mask.”
