In the "draft" changes to the CDC website, they included a preventative measure about ventilation, stating "Airborne viruses, including COVID-19, are among the most contagious and easily spread".
"Most public health organizations, including the World Health Organization, do not recognize airborne contamination, except for aerosol formulation procedures performed on health systems". They also said there is a possibility the study undercounts the actual number of those meeting the CDC guidelines for the risk of contracting COVID-19 and being connected to a school.
"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 said in the Friday update, which has since been removed. It also cautioned against spending time at poorly ventilated indoor locations.
Monday's reversal may also increase public skepticism about the agency's messaging on COVID-19 more broadly. Click the link to confirm your subscription and begin receiving our newsletters. The move is yet another misstep for the nation's leading public health agency, which recently reversed its guidance for the second time on testing asymptomatic people for the coronavirus.
CDC Reverses COVID Test Guideline After Controversy
After analyzing the case of two worldwide flights in which at least 18 people were infected by passengers sick with COVID-19, two investigations by the Centers for Disease Control and Prevention of the United States (CDC) indicate that the coronavirus can be spread during flights. The main intent seemed to be to assure state health officials that they could continue to recommend that all close contacts be tested if they felt that was wisest, despite the website language that said it was not necessary.
The CDC did not respond Sunday to requests to discuss the update.
The guidelines, which said testing was not necessary for people who were exposed to COVID-19 but not displaying symptoms, were criticised when they were issued last month.
Wherever you are, keeping a good measure of distance between yourself and others is still a good idea, but if you're indoors, or in a crowded space, keeping your mask on, staying quiet, and making interactions brief can all help mitigate the spread.
