Is COVID ariborne?? World Health Organization (WHO) is reviewing it with deep concern

The World Health Organization (WHO) is reviewing a report urging it to update guidance on the novel coronavirus after more than 200 scientists, in a letter to the health agency, outlined evidence the virus can spread in tiny airborne particles.

The WHO says SARS-CoV-2, the virus that causes COVID-19, spreads primarily through small droplets expelled from the nose and mouth of an infected person that quickly sink to the ground.

But in an open letter to the Geneva-based agency, published on Monday in the Clinical Infectious Diseases journal, 239 scientists in 32 countries outlined evidence that they say shows floating virus particles can infect people who breathe them in.

Because those smaller particles can linger in the air, the scientists are urging WHO to update its guidance.

Professor Babak Javid, an infectious disease consultant at Cambridge University Hospitals, said airborne transmission of the virus is possible and even likely, but said evidence over how long the virus stays airborne is lacking.

If it can hang in the air for long periods of time, even after an infected person leaves that space, that could affect the measures healthcare workers and others take to protect themselves.

WHO guidance to health workers, dated June 29, says SARS-CoV-2 is primarily transmitted through respiratory droplets and on surfaces.
