CDC website now emphasizes coronavirus spreads in the air - CNN

The changes to the CDC website are in line with a gradual shift in the agency's advice to stress that the virus spreads through the air -- either to be breathed in, to get into the eyes or to settle onto surfaces that people later touch.

"COVID-19 spreads when an infected person breathes out droplets and very small particles that contain the virus.

Less commonly, people catch the virus from breathing air contaminated by people who are further away, or by touching a contaminated surface and then touching their own eyes, nose or mouth.

"If you and I are standing within a few feet of each other talking, we now know infectious particles are flying out, even if you are talking softly," Brooks said.

The new explanations do not change what people need to do, but might help the public better understand how the virus spreads, Brooks said.

And get vaccinated.

The CDC also updated its scientific brief on how the virus spreads.

"Modes of SARS-CoV-2 transmission are now categorized as inhalation of virus, deposition of virus on exposed mucous membranes, and touching mucous membranes with soiled hands contaminated with virus," the new guidance reads."The principal mode by which people are infected with SARS-CoV-2 (the virus that causes COVID-19) is through exposure to respiratory fluids carrying infectious virus," it adds.

CDC added to its science brief on mask use to counter fears about the safety of wearing masks.
