The Centers for Disease Control and Prevention in a new guidance acknowledged that COVID-19 can spread through the air, then swiftly walked back the change. The CDC's website as of Friday described COVID-19 as "airborne," saying the coronavirus commonly spreads "through respiratory droplets or small particles, such as those in aerosols" and that "there is growing evidence that droplets and airborne particles can remain suspended in the air" and "travel distances beyond 6 feet." Experts who previously pointed to evidence that the coronavirus is airborne welcomed the new guidance, but on Monday, the website was updated once again. The guideline was removed, and a CDC official said "that does not reflect our current state of knowledge." The website says the "proposed changes" were "posted in error."
