The confirmation from the international health authority comes days after more than two hundred experts warned him in an open letter.
After several warnings, the World Health Organization (WHO) accepted this Thursday that COVID-19 could be spread by air in some circumstances.
According to the newspaper The country, the international organization for the first time since March 29, it updated the document detailing the virus transmission modes to include the calls aerosol spraysThese small particles that can keep a viral load suspended for a few minutes and infect those who inhale it.
On Monday, a group of 239 international scientists urged WHO and the international medical community to “recognize the possible air transmission of COVID-19”, in an article published in the magazine Clinical Infectious Diseases from Oxford.Coronavirus in Honduras. EFE / Gustavo Amador / Archive
Regarding airborne infections, the WHO statement is very cautious, since they affirm that the tests are indirect. Furthermore, many Specialists had warned that warning of airborne contagion could be misinterpreted by the population.
As described in the new document of the agency, have been outbreaks in “some closed environments, such as restaurants, nightclubs, places of worship or workplaces where people can be screaming, speaking or singing“
“In these outbreaks,” he notes, “The transmission of aerosols cannot be ruled out, particularly in these interior places where there are crowded spaces and inadequate ventilation where infected people spend long periods of time with others.”People in facial masks line up in Havana, Cuba, July 8, 2020.

Closed premises, with poor or no ventilation and many people talking (the stronger, the worse) for a long time: these four factors added together appeared as the most likely cause of transmission in several outbreaks studied by epidemiologists since February and March in different parts of the world.
Some of the known cases are a choir rehearsal in which hygiene and safety distance were maintained, several outbreaks in karaokes, a restaurant where diners from neighboring tables caught, a gym where you practiced buzz, and a journey in long-distance bus in which no facial masks or ventilation were used.
The experts were clear that the most plausible route of contagion was those aerosols, virus particles that are suspended and can be breathed. Until now, the health authorities only accepted this contagion by aerosols at the time when patients with COVID-19 were intubated, according to The country, but not for habitual situations between citizens.File image of passengers wearing face masks sitting on a plane at Sharm el-Sheikh International Airport, amid the COVID-19 pandemic, the disease caused by the coronavirus, in Sharm el-Sheikh, Egypt.

The WHO, already criticized for having been slow to advise the use of masks, She was accused of not wanting to admit the evidence that points to the airborne spread of the new coronavirus, which has already killed more than 500,000 people in six months.
On Tuesday, the institution had insisted that the epidemic “accelerates, and we have not reached the peak of the pandemic”, in the words of its CEO, Tedros Adhanom Ghebreyesus.
“Although the death toll appears to have stabilized globally, in reality, some countries have made significant progress in reducing the number of cases, while in others the deaths continue to grow ”he said at a press conference.
