Is 6 feet enough? CDC walks back its walkback on airborne transmission of COVID-19 – By John Bacon (USA Today) / Sept 21 2020
The Centers for Disease Control and Prevention, which quietly changed its guidance on coronavirus transmission through the air Friday, reversed field again Monday.
On Friday, the CDC posted an update on its website saying six feet may not be sufficient to keep people safe and that ventilation was key to easing transmission indoors. That determination could be crucial for schools where desks are now set up six feet apart. Offices, restaurants and even church services also could be affected by the change.
“There is growing evidence that droplets and airborne particles can remain suspended in the air and be breathed in by others, and travel distances beyond 6 feet (for example, during choir practice, in restaurants, or in fitness classes),” the agency said. “In general, indoor environments without good ventilation increase this risk.”
