The World Health Organization (WHO) disclosed on Monday that it has not changed its policy on the aerosol transmission of the coronavirus disease, after United States health officials mistakenly drafted new guidance, warning that it could be transmitted through airborne particles.
While making the disclosure in a press briefing, the Executive Director of WHO’s Emergency Programme, Mike Ryan, said that he would follow up with the US Centers for Disease Control and Prevention (CDC) in the next 24 hours, after it said COVID-19 could spread through airborne particles that could remain suspended in the air and travel beyond six feet.
In a briefing, Mike Ryan said, “Certainly we haven’t seen any new evidence and our position on this remains the same.”
Nairametrics had earlier reported that the WHO while providing an update on the mode of transmission of SARS-CoV-2 (the virus that caused the Covid-19) from infected people, revealed that based on new scientific evidence, the coronavirus can be transmitted indoors by droplets in the air.
The UN health agency, in a scientific brief, said that people who spend time in crowded places with poor ventilation are at risk of being infected by the coronavirus as the droplets circulate throughout the air in indoor gatherings.
The CDC said that a draft version of changes to its recommendations were posted in error on its website, while it was in the process of updating its guidance.
It, however, said that the guidance would be reposted as soon as it had completed the review.
The CDC previously disclosed that the virus mainly spread from person to person through respiratory droplets when a sick person coughed, sneezed or talked.
The WHO’s Ryan said the agency still believes the disease is primarily spread through droplets, but that in crowded closed spaces with inadequate ventilation, aerosol transmission can occur.
He said, “We still, based on the evidence, believe that there is a wide range of transmission modes.”
