A day after a group of scientists said the global body was underplaying the risk of airborne transmission between people, a senior WHO official said there was “evidence emerging” of airborne transmission of the coronavirus, but that it was not definitive.
Speaking at a media briefing in Geneva on Tuesday, Benedetta Allegranzi, the WHO’s technical lead for infection prevention and control, said: “...The possibility of airborne transmission in public settings – especially in very specific conditions, crowded, closed, poorly ventilated settings that have been described, cannot be ruled out.
“However, the evidence needs to be gathered and interpreted, and we continue to support this.”
The WHO has previously said the virus that causes the Covid-19 respiratory disease 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 exhaled particles can linger in the air, the scientists in the group had been urging WHO to update its guidance.
La science avance lentement... alors que le génome du virus a été séquencé à une vitesse incroyable. Étonnant.
