WHO admitted: COVID-19 contamination in the air is possible, evidence is being studied

The World Health Organization has acknowledged that there is evidence that coronavirus can spread by tiny particles suspended in the air. The organization stated that air transmission cannot be ruled out in crowded, closed, or poorly ventilated places. If the evidence is confirmed, this may affect the recommendations for the premises, reports the BBC.

An open letter from over 200 scientists openly accused WHO of underestimating the possibility of airborne transmission. To date, WHO has stated that the virus is transmitted through drops when people cough or sneeze.

In healthcare facilities, if the airborne transmission is a particular risk, healthcare professionals should wear the best preventative equipment. However, the World Health Organization said that one of the reasons they did not want to talk about Covid-19 aerosol transmission was because such a number of specialized masks were not enough for many parts of the world.

WHO officials warned that the evidence is preliminary and requires further evaluation. Benedetta Allegranzi, WHO Technical Director for Prevention and Control of Infections, said that evidence of coronavirus aerial transmission in crowded, closed, poorly ventilated environments cannot be ruled out.

Earlier, for several months, WHO insisted that COVID-19 is transmitted through drops released by coughing or sneezing.

But 239 scientists from 32 countries do not agree. They claim that there is convincing evidence of the spread of the virus in the air: through the smallest particles that float for several hours in the air after people talk or exhale.

WHO has now acknowledged that there is evidence that this is possible under certain conditions when it comes to closed and crowded spaces.

This evidence should be carefully evaluated, but if it is confirmed, recommendations on how to prevent the spread of the virus may change, and this may lead to wider use of masks and more stringent distance, especially in bars, restaurants, and in public transport.
