WHO, on Tuesday, acknowledged the emerging evidence about the airborne spread of the coronavirus. The international organization was pursued by a group of scientists asking them to update their guidelines and measures for people regarding the spread of the disease and how it is passed amongst people.
Maria Van Kerkhove, technical lead on coronavirus pandemic in WHO, said in a press briefing that the organization has been discussing the possibilities of aerial spread of the virus and aerosol being one of the modes through which this virus can be transmitted from one person to another.
So far, WHO had said that the virus is transmitted primarily through small droplets that come out of the mouth or nose of the infected person.
A letter by 239 scientists of 32 countries addressed to WHO was published in the Clinical Infectious Diseases journal on Monday, which outlined the evidence which showed that people could get infected if he or she breathes in the floating virus particles in the air. Scientists say the smaller particles exhaled by an infected person can stay afloat in the air for a longer time and can end up infecting others who breathe that air in.
Scientists have urged WHO to change its guidelines so that people can be aware of the new findings and can take appropriate precautions.
