(CNN) – The U. S. Centers for Disease Control and PreventionBut it’s not the first time They returned Monday to their previous rules on the transmission of the coronavirus, cutting the wording on air transmission that they had published a few days earlier.
“A draft of the proposed adjustments to those recommendations mistakenly posted on the agency’s official website. The CDC is recently updating its recommendations related to air transmission of SARS-CoV-2 (the virus that causes COVID -19) Once this procedure is complete, the update language will be published,” said Jason McDonald, a CDC spokesperson, in a reaction emailed to CNN.
The rules were about how the new coronavirus is spreading. Although it is known to spread through drops among others less than 6 feet away, studies have continued to explore how the virus is suspended in aerosol waste in the air and transmitted to others. more than 6 feet away.
The CDC broadcast consultant that detected airborne broadcast quietly released Friday, according to the agency’s website CNN, the first to report the replacement on Sunday. The CDC responded to CNN just before noon Monday to say it goes back to earlier consultant lines.
A federal official with knowledge of the scenario said there is no political tension in the change.
“It was done completely through the CDC,” the official said. “It was published by mistake. It is not in a position to be published. “
The official said the management replacement had been published very carefully through CDC experts.
“Someone pressed the button and did, ” said the official.
The firm tried to explain more what it meant through aerosol transmission, the official said. “This can happen, but it’s not the way the virus is basically transmitted,” the official said. But in the effort to say this, he wrote in such a way that “it means that it is more communicable than we thought, which is not the case. “
The official added that the rules were “under review,” but specified when the review would be published on the CDC website.
Despite several studies that have shown that the new coronavirus can spread through small debris in the air, the CDC page now states that Covid-19 basically spreads among others in close contact, about six feet, and “through the respiratory droplets produced when the user coughs, sneezes or speaks. This is the same language that the firm launched months ago.
In language published on Friday and now eliminated, the CDC said that Covid-19 spreads among others in close contact with each other, and went on to say that it spreads “through the breathing of droplets or small particles, such as those containing aerosols, produced when an inflamed user coughs, sneezes Array sings, speaks or breathes”.
These debris can cause infection when “inhaled through the nose, mouth, airlines and lungs,” the firm said. “It’s an idea to be the main spread factor for the virus. “
”There is growing evidence that drops and debris in the air can remain suspended in the air and be inhaled through others, and travel distances of more than 6 feet (e. g. choir practice, in restaurants or in gym classes) ”, says the page. Friday update, which has since been removed. “In general, indoor environments without adequate ventilation increase this risk. “
In Friday’s update, the CDC added new measures to protect it from others, adding recommendations for the use of air purifiers to decrease indoor air germs and transparent tips to “stay at least 6 feet away from others whenever possible. “The date on the CDC page had also replaced language about asymptomatic transmission, from ‘some other people without symptoms could possibly spread the virus’ to ‘other people who are inflamed but have no symptoms can transmit the virus to others. ‘has now been eliminated.
Many researchers and doctors have been saying for months that coronavirus can be transmitted through small viral particles in the air. In July, 239 scientists published a letter urging the World Health Organization and other public fitness organizations to be more open about the likelihood that others will simply contract the virus from droplets floating in the air.
Donald Milton, of the letter and professor of environmental fitness at the University of Maryland, said he felt “encouraged” when he saw the revised CDC rules over the weekend, but said he suspected it was a chart in progress from the rest of the CDC. The site was out of date to reflect the changes.
“I think the science behind what turned out to be a draft is forged and consistent with my understanding of knowledge,” Milton said. “I am very pleased to know that CDC is working to incorporate the newest clinical knowledge into its Today, we know a lot about aerosols and how to control them to prevent transmission.
Dr Mike Ryan, Executive Director of the World Health Organization’s Health Emergencies Program, said that if the US is not able to do so. But it’s not the first time Waiting for the CDC’s latest recommendation, the world can’t wait to find tactics to prevent the spread of the disease.
“According to evidence, [WHO] believes there is a wide variety of modes of transmission,” Ryan said. “We believe that the disease spreads basically or basically through the spread of larger droplets and droplet nuclei. But we have said that smaller droplet nuclei can spread this disease, and this is closely context-related.
Ryan explained that others in a small internal domain with poor ventilation may become inflamed through aerosol transmission. It’s about knowing the dangers and “managing the frequency, intensity and duration” of time they spend with other people in crowded spaces, he said.
“We have to be able to settle for the very few absolutes in this response,” Ryan added. “We want to be wise and make wise decisions, wise decisions are made based on understanding threats, minimizing threats, and then raising awareness of the residual threat. “, and as productive as we can to avoid it. “
Some feared that immediate CDC updates would be similar to previous reports of political tension and interference within the agency.
On Friday, the CDC updated its coronavirus testing recommendation to emphasize that anyone who has been in contact with an inflamed user undergoes the coronavirus test. An earlier, debatable update was not written through CDC scientists and was posted online before being tested. general clinical review process, two resources showed CNN last week.
CNN also reported last week that U. S. social and fitness officials have been able to do so. But it’s not the first time They had recently pushed to replace the language of the CDC’s weekly clinical reports so as not to undermine President Donald Trump’s political message, according to a CNN federal fitness official. said last week that “at no point had the clinical integrity” of the reports been compromised.
On Monday, Dr. Leana Wen, an emergency doctor at George Washington University and a CNN medical analyst, said she feared that sudden adjustments to CDC rules would be driven more by politics than by science.
“The fact that they have retracted, even though it is a clinical wisdom not unusual at this stage, one has to wonder what it is,” he said. “Has there been any political pressure? Political interference that leads to this rather than science?»
Science, he said, deserves to succeed over politics at the CDC.
“It’s not a matter of politics,” Wen said. “It’s not about what looks good. It’s about following the science to know the number of infections and the number of deaths. “
In any case, the CDC’s revocation can confuse and hinder mitigation efforts that can be put in place.
“It’s incredibly confusing, and this kind of whiplash, especially without a direct explanation from the CDC, is confusing and, unfortunately, leads to a lack of acceptance as true in the CDC as a whole,” Wen said.
