The Center for Disease Prevention of America updates its guidance on the spread of Corona through the air

Yesterday, Friday, the American Centers for Disease Control and Prevention updated its directives on how the Corona virus is transmitted, stressing that inhalation is one of the main ways of spreading the virus, with less emphasis on the risks of catching infection from surfaces, according to what was published by the American "CNN" website.

The changes to the CDC website are in line with a gradual shift in CDC advice to emphasize that the virus spreads through the air - either by breathing, to reach the eyes or to settle on surfaces that people later touch.

The CDC stated on its website: “Corona virus spreads when an infected person breathes in very small drops and particles that contain the virus. These droplets and particles can be inhaled by other people or land on their eyes, noses, or mouths. In some circumstances, the surfaces that people touch may contaminate them. Within 6 feet or two meters from an infected person, they are most vulnerable. "

Dr. John Brooks, chief medical officer for the Corona response at the US Center for Disease Control, said: "How people can become infected with this virus can be summarized in three very simple concepts ... keep the air clean, avoid exposure to mucous membranes and keep your hands clean."

According to the new data, people contract the virus more commonly when they stand near an infected person and the particles fly either to land on the face or to breathe, and less commonly, people contract the virus from inhaling polluted air from distant people, or by touching a contaminated surface and then touching their eyes or nose. Or their mouth.

"If you and I stood a few feet away from each other talking, we now know that infectious particles are flying, even if you are talking quietly," Brooks said.

Brooks said the new explanations do not change what people need to do, but they may help the public better understand how the virus is spreading. The guidance stays the same - wear a mask when near other people or indoors, share air with others, keep your distance from others when possible, wash your hands frequently and get vaccinated.

The CDC has also updated its science brief on how the virus is spreading.

The new directives state that "the patterns of corona virus transmission are now classified as inhaling the virus, deposition of the virus on exposed mucous membranes, and touching the mucous membranes with hands contaminated with the virus."

The CDC added to its scientific brief on the use of the mask to address concerns about the safety of wearing masks, and the study said: "Research supports that wearing a mask does not have significant adverse health effects on the wearer."

Brooks pointed out that masks do not just filter the air, as wearing a mask covers mucous membranes and it is difficult to touch your mouth when the mask covers it.
