Yesterday, Monday, the US Centers for Disease Control and Prevention officially announced that the emerging corona virus can be transmitted through the air, in a position consistent with the views of many scientists who have been calling for months to take this possibility more seriously.
Yesterday, Monday, the US Centers for Disease Control and Prevention updated its health recommendations published on its website as follows: “Some infections can be transmitted in small droplets and particles that can float in the air for minutes or hours. These viruses may be able to infect people. They are about two meters away from the injured person, or after leaving. ”
Among the diseases that are transmitted through the air in addition to Covid-19, measles, smallpox and tuberculosis.
The experts of the American Centers for Disease Control and Prevention consider that the main method of transmission remains respiratory droplets of various sizes that are dispersed by the infected person when sneezing, coughing, singing, speaking and breathing.
But the update that comes ten months after the start of the pandemic confirms the validity of studies showing that the Corona virus, although it is the least contagious of measles, can be transmitted more than two meters, a hypothesis that was excluded by the American Centers for Disease Control and Prevention and the World Health Organization when the SARS virus appeared – COF-2.
The centers stress the importance of indoor ventilation to avoid infection, and on the other hand, they do not consider the transmission of infection “through surfaces contaminated with the virus, a common method for the spread of Covid-19.”
As for the recommendations of this authority, there has been no amendment to the precautions that must be taken: physical distancing, wearing masks, washing hands, avoiding crowded closed spaces, and isolating the sick.
A group of American scientists was pushing to update the official health recommendations, which were based on an outdated distinction between droplets and aerosols dating back to the 1930s.
And yesterday, Monday, experts at the universities of California, Maryland, Virginia Tech and others wrote in a joint letter that “viruses in aerosols can float in the air for seconds and hours, like smoke, and can be inhaled.”
