May 10, 2021 – The United States Centers for Disease Control and Prevention on Friday amended its website guidelines on the spread of the coronavirus, pointing out that it is mainly transmitted through the air, not on surfaces.
“COVID-19 is spread when an infected person exhales droplets and very small particles that contain the virus. These droplets and particles can be inhaled by other people or land on their eyes, nose or mouth, the agency said. circumstances, they can contaminate the surfaces they touch. People who are within six feet of the infected person are most likely to be infected. “
“How people get this virus can be boiled down to three very simple concepts,” said Dr. John Brooks, CDC’s chief medical officer for the COVID-19 response. CNN. “Keep the air clean, avoid exposing yourself to your mucous membranes, and keep your hands clean.”
The virus is most often caught by standing near an infected person and virus particles land on the face or are inhaled. It is less common to get the virus by breathing contaminated air from people farther away, or by touching a contaminated surface and then touching the eyes, nose or mouth. CNN mentionned.
“If you and I stand a few feet away from each other talking, we now know that infectious particles are flying up, even if you speak quietly,” Brooks said.
This new information doesn’t change what people should do, but can help people understand how the virus is spread, Brooks said.
People should always wear a mask when around or indoors, keep away from others, wash their hands often, and get vaccinated.
The CDC added that “Research supports that wearing a mask does not have significant adverse effects on the health of wearers.
“Masks don’t just filter the air,” said Brooks. CNN. “Wearing a mask covers your mucous membranes. It is more difficult to touch your mouth when a mask is placed on it,” he added.
Some scientists say the CDC guidelines are still misleading. The CDC says that “breathing small droplets and particles [i.e., aerosols] that contain the virus when people are away from each other or have been in the same confined space for more than a few minutes is rare.
