Covid-19. U.S. health authority ensures contagion can occur with airborne particles


The Centers for Disease Control and Prevention (CDC), the United States of America (USA) disease control and prevention authority, 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 about Covid-19 noting that “some infections can be propagated 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 he leaves 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 contagions occurred in closed spaces that had inadequate ventilation” and sometimes “the infected person had a stronger breath, for example when singing or exercising”, adds the same entity.

The additional information comes after the CDC last month eliminated a publication on the transmission of coronavirus because it concluded that the terms in which it was drafted mislead readers, allowing the interpretation that Covid-19’s main form of contagion 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 propagation 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.
