The study released on Thursday said that people who are obese and have high blood pressure are most at risk, and men are more susceptible to the virus than women. "CDC is now updating its recommendations regarding airborne transmission of SARS-CoV-2 (the virus that causes COVID-19)".
The CDC website now says testing is recommended for all close contacts of persons with SARS-CoV-2 infection.
"There is evidence that water droplets and airborne particles can be suspended in the air and inhaled by others, and travel distances beyond 6 feet (e.g. during singer training, in restaurants or fitness classes)", says Page now. It also cautioned against spending time at poorly ventilated indoor locations.
Experts anxious the CDC guidance - which applied to both asymptomatic close contacts as well as those who attended large, risky gatherings but had no symptoms - would exacerbate those challenges.
It reportedly came from the Department of Health and Human Services.

The previous phrasing, which suggested asymptomatic people who have had close contact with an infected individual "do not necessarily need a test", now clearly instructs them: "You need a test".
According to Politico, CDC last month received criticism from public health experts when the agencyrevised its coronavirus testing guidelines to exclude recommendations that people who were exposed to the novel coronavirus but who were not exhibiting symptoms of Covid-19 undergo testing.
"A single negative test does not mean you will remain negative at any time point after that test", CDC wrote in the guidelines.
The CDC did not respond Sunday to requests to discuss the update.
In a now-infamous March choir practice investigated in Washington state, 53 people got COVID-19, the illness caused by the coronavirus, from one sick choir member, even though they were all social distancing (but not wearing masks) during practice. But in July, under increasing pressure from researchers, the World Health Organization acknowledged that the virus could remain in the air indoors and possibly infect humans.even when exercising social distances.
The new CDC guidance was swiftly retracted late Monday morning, with the agency saying that "a draft version" had been "posted in error".
In the Friday update, the CDC had added new measures to protect yourself in others, including recommendations to use air purifiers to reduce airborne germs in indoors spaces and clear guidance to "stay at least 6 feet away from others, whenever possible".
