It was "an honest mistake" that happened when a draft update was posted before going through a full editing and approval process, said Dr. Jay Butler, the CDC's deputy director for infectious diseases.
For months, however, public health experts have repeatedly stated that the novel coronavirus can also be transmitted through tiny droplets known as aerosols and have urged health agencies to acknowledge this mode of transmission. However, the question remains on whether the virus spreads through the air or not. A person may get COVID-19 by touching the surface or object that has the virus on it and then touching their own mouth, nose, or eyes. But research is continuing to explore the possibility of the virus staying in the air for farther than the six feet distance. It also cautioned against spending time at poorly ventilated indoor locations.
The post caused widespread discussion in public health circles because of its implications. This week, the scientific journal Indoor Air accepted a paper for publication that found that numerous 53 choir singers who became sick after attending a March 10 practice in Mount Vernon, Wash., likely caught COVID-19 through airborne transmission.
There have been a number of controversial guidance changes from the CDC and FDA over the last few weeks.
"We find ongoing reports and incidents of the politicization of science, particularly the overriding of evidence and advice from public health officials and derision of government scientists, to be alarming", the statement said. "This was an internal issue, ".
"Everybody wants a vaccine, but we want to make sure that that vaccine is safe", Sen.
Jimenez and Milton said it's important to wear masks to reduce the risk of spreading and contracting COVID-19.
The virus spreads "through respiratory droplets or small particles, such as those in aerosols, produced when an infected person coughs, sneezes, sings, talks, or breathes", the new CDC guidance said. "This was an error on the part of our agency, and I apologize on behalf of the CDC", he said. One source said the FDA is expected to tell vaccine makers they need to wait two months after giving all their study participants their second doses of the vaccine before applying for emergency use authorization.
