The Centers for Disease Control and Prevention (CDC), the disease control and prevention authority of the United States of America (USA), has revised its assessment of Covid-19 transmission, now admitting that Coronavirus infections can occur through small particles that are suspended in the air.
This Monday the CDC came to update its information on Covid-19 noting that “some infections can be spread by exposure to the virus in droplets and particles that can remain in the air for minutes or hours”, and can infect people who are more distant two meters from the infected person and even after leaving the space where he was.
“There is evidence that, under certain conditions, people with Covid-19 appear to have infected others who were more than two meters away,” says the CDC. “These infections occurred in closed spaces that had inadequate ventilation” and sometimes “the infected person had stronger breath, for example when singing or exercising,” adds the same entity.
The additional information comes after last month the CDC removed a post about the transmission of the coronavirus because they concluded that the terms in which it was written mislead readers, allowing the interpretation that the main form of contagion of Covid-19 would be by the particles that are suspended in the air.
Although it now admits the possibility of contagion by particles suspended in the air for long periods, the CDC maintains the indication that the main form of spread is through close contact between people, when one, infected with Covid-19, coughs, sneezes or breathes on top of another, transmitting the virus through droplets.
