That's been the most likely case for quite some time.
The Centers for Disease Control and Prevention in a new guidance has acknowledged that COVID-19 can spread through the air, CNN reports.
The CDC's website as of Friday says that "airborne viruses, including COVID-19, are among the most contagious and easily spread" and that the coronavirus commonly spreads "through respiratory droplets or small particles, such as those in aerosols."
The CDC's latest guidance also says, "It is possible that COVID-19 may spread through the droplets and airborne particles that are formed when a person who has COVID-19 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 guidance from the CDC, CNN notes, previously described COVID-19 as mainly spreading through "respiratory droplets produced when an infected person coughs, sneezes or talks" and within six feet. In the new guidance, when listing ways to protect oneself from COVID-19, in addition to steps such as social distancing and wearing a mask, the CDC also now says to "use air purifiers to help reduce airborne germs in indoor spaces."
The Washington Post notes that "scientists and public health experts have warned of mounting evidence that the novel coronavirus is airborne" for months, and University of Colorado at Boulder chemistry professor Jose-Luis Jimenez told the Post this acknowledgement from the CDC as a "major change."
"This is a good thing," Jimenez told the Post, "if we can reduce transmission because more people understand how it is spreading and know what to do to stop it."
Additionally, University of Maryland professor Donald Milton told CNN it's a "major improvement," adding, "I'm very encouraged to see that the CDC is paying attention and moving with the science. The evidence is accumulating."
