The disease control agency updated its website amid a debate among scientists on how the coronavirus spreads.
"The CDC updated its website on Friday amid a debate among scientists on whether the coronavirus is airborne. It states the virus can be passed on "through respiratory droplets or small particles, such as those in aerosols produced when an infected person coughs, sneezes, sings, talks, or breathes."
Before, the CDC said the germ could pass "through respiratory droplets produced when an infected person coughs, sneezes, or talks."
The CDC now says: "These particles can be inhaled into the nose, mouth, airways, and lungs and cause infection. This is thought to be the main way the virus spreads."
