May 10, 2021 – U.S. Centers for Disease Control and Prevention changed its website on Friday coronavirus it extends, emphasizing that it is transmitted mainly by air, not by surfaces.
“COVID-19 spreads when an infected person breathes in drops and very small particles that contain the virus. These drops and particles can be inhaled by other people or land in their eyes, noses or mouth,” he said. agency. circumstances, they can contaminate the surfaces they touch. People who are closer to 6 feet from the infected person are more likely to become infected. “
“How people against this virus can be reduced to three very simple concepts,” said Dr. John Brooks, chief physician of the CDC’s COVID-19 response. CNN. “Keep the air clean, avoid exposing yourself to yours moc membranes and keep your hands clean “.
The virus is most often reached near an infected person and virus particles land on the face or are inhaled. It is less common to catch the virus by breathing polluted air from people who are farther away or touching a contaminated surface and then touching their eyes, nose or mouth. CNN dit.
“If you and I are a few feet away from each other talking, we now know that infectious particles fly out, even if you talk softly,” Brooks said.
This new knowledge does not change what people should do, but it can help them understand how the virus spreads, Brooks said.
People should still wear a mask when they are close to other people or indoors, stay away from others, wash their hands often, and get vaccinated.
The CDC added that “research supports that the use of masks has no significant adverse effects on the health of users.
“Masks don’t just filter the air,” Brooks said CNN. “Wearing a mask covers the mucous membranes. It’s harder to touch your mouth when there’s a mask,” he added.
Some scientists say the CDC guidelines are still misleading. The CDC says it “breathes small drops and particles [i.e., aerosols] containing the virus when people are away or have been in the same enclosed space for more than a few minutes is uncommon.
