US CDC flip flops on calling Covid-19 airborne


The Centers for Disease Control and Prevention edited its web page describing how the novel coronavirus spreads, removing recently added language saying it was “possible” that it spreads via airborne transmission.

It was the third major revision to CDC information or guidelines published since May.

The agency had posted information on Friday stating the virus can transmit over a distance beyond six feet, suggesting that indoor ventilation is key to protecting against a virus.

Earlier, the US CDC updated guidance on its website to say coronavirus can commonly spread “through respiratory droplets or small particles, such as those in aerosols,” which are produced even when a person breathes.

“Airborne viruses, including Covid-19, are among the most contagious and easily spread,” the site now says.

Previously, the CDC page said that Covid-19 was thought to spread mainly between people in close contact — about six feet — and “through respiratory droplets produced when an infected person coughs, sneezes or talks.”

In India, the government said this in a written Parliament reply when asked if Covid-19 was airborne:

“Airborne transmission of the virus can occur in health care settings where specific medical procedures, called aerosol generating procedures, generate very small droplets called aerosols. Government of India in its guidelines on rational use of Personal Protective Equipment (PPE) has accounted for the possibility of airborne transmission in aerosol generating procedures and has recommended appropriate PPEs for all such settings.”

“According to World Health Organization (WHO), current evidence suggests that transmission of SARS-CoV-2 occurs primarily between people through direct, indirect, or close contact with infected people through infected secretions such as saliva and respiratory secretions, or through their respiratory droplets, which are expelled when an infected person coughs, sneezes, talks or sings.”
