“We have already talked about the possibility of airborne and aerosol spread as a way of spreading Covid-19,” said Maria Van Kerkhove, technical head of the Covid-19 pandemic at WHO.
The WHO previously said the corona virus spreads more through droplets or small droplets that come out of the nose and mouth of an infected person which quickly falls down.
But in an open letter to WHO released in the journal Clinical Infectious Diseases, 239 researchers in 32 countries provided evidence that they found that virus particles that float in the air can infect people who breathe it.
Because the inhaled particles can be in the air, the researchers asked WHO to update the guidelines.
Speaking in Geneva, Benedetta Allegranzi, WHO’s technical head for infection prevention and control said there was evidence of the spread of the corona virus by air, but that was not definitive.
“The possibility of spreading in the air in public places, especially in very special conditions, dense, closed, poor ventilation as mentioned, cannot be ignored,” he explained.
“However, evidence needs to be collected and translated, and we continue to support this,” he said. (See Infographics: 8 Activities You Can Do to Relieve Stress)
Any changes to the risk assessment of spread can affect the current call to maintain a distance of 1-3 meters. Countries that depend on WHO for guidance policies may have to adjust public health measures to prevent the spread of the corona virus.
