The Centers for Disease Control and Prevention updated its COVID-19 rules to recognize the threat that coronavirus can be transmitted through respiratory waste in the air, but then replaced its online page Monday morning to remove this information, claiming it was still under review.
Prior to its elimination, updated rules indicated that the maximum coronavirus spreads “through the breathing of droplets or small particles, such as those contained in aerosols,” which occur when an inflamed user coughs, sneezes, sings, speaks, or even simply breathes. , and may remain in flight for a while. The virus can then spread to others who inhale it into their airways.
Many scientists and fitness experts have warned for months that COVID-19 can spread through respiratory particles in the air, only the giant drops of an inflamed user coughing or sneezing near the ground.
“It’s becoming increasingly transparent that drops and debris in the air can stay suspended in the air and breathe through others, and travel distances of more than 6 feet (e. g. choir practice, restaurants, or gym classes),” the CDC said. , but then removed, according to the guidelines. ” In general, indoor environments without adequate ventilation increase this risk. “
But on Monday, the CDC updated the page to remove data on the air transmission threat, with a warning at the top: “A draft of the proposed adjustments to those recommendations was mistakenly posted on the agency’s official website. “says. ” The CDC is recently updating its recommendations for air transmission of SARS-CoV-2 (the virus that causes COVID-19). Once this procedure is complete, the update language will be published. “
The page still states that the virus spreads “through respiratory droplets that occur when an inflamed user coughs, sneezes or speaks”, however, data on droplets in the air, such as aerosols, have been deleted. the virus.
On the other hand, the page says, “These droplets may fall into the mouth or nose of others nearby or are likely to inhale into the lungs. “Monday’s update also indicates that COVID-19 spreads primarily among others who have a touch (within 6 feet) and understands that it can be passed on to others who have no symptoms.
In July, the World Health Organization (WHO) identified air transmission of “microdrops” as a imaginable cause of COVID-19 infections. WHO’s popularity came after 239 scientists signed an open letter about the threat of air transmission.
Very few diseases, such as tuberculosis, chickenpox and measles, have been found to be transmitted through aerosols; however, Japan, for example, had been operating for months on the assumption that small traces of aerosols in overcrowded environments were fueling the spread of coronavirus. Japan followed a strategy to combat COVID-19 air transmission by telling citizens the “three Cs”: confined spaces, crowded spaces, and close conversations.
Cdc also dictates that the closer a user is with COVID-19 to others, the greater the threat of spreading the virus to those people.
On Friday, the CDC also updated its test rules after nearly a month of controversy over the role of political interference through Department of Health and Human Services officials over overcoming CDC scientists. Last August, the CDC’s online page was silently reviewed to imply that others who had been exposed to a user with coronavirus but who had no symptoms may not want to be tested. This has sparked a protest among medical experts, as other asymptomatic people can easily transmit the virus to others.
The new consultant now says: “Due to the importance of asymptomatic and presymptomatic transmission, this consultant further reinforces the desire to control asymptomatic people, adding close contact of a user with a documented SARS-CoV-2 infection.
Many public fitness experts have long pleaded for even other asymptomatic people to get tested if they suspect they have been in contact with an inflamed person. In July, a style published through the National Academy of Sciences showed that about 50% of coronavirus cases can be transmitted through others who have no symptoms.
