The US Centers for Disease Control and Prevention (CDC)'s page still says Covid-19 most commonly spreads between people who are in close contact with one another, and now says the virus is known to spread "through respiratory droplets or small particles, such as those in aerosols, produced when an infected person coughs, sneezes, sings, talks or breathes."
"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 page now says. "In general, indoor environments without good ventilation increase this risk."
These particles can cause infection when "inhaled into the nose, mouth, airways, and lungs," it says. "This is thought to be the main way the virus spreads."
The CDC also added new measures to its information about protecting yourself and others.
