The Centers for Disease Control and Prevention reversed the course on Tuesday with some masking guidelines, recommending that even vaccinated people wear masks indoors in parts of the United States where the coronavirus is rampant. ..
The CDC cites new information about the ability of delta variants to spread to vaccinated people and recommends indoor masks to all teachers, staff, students, and school visitors, regardless of vaccination status. did.
Following recent decisions in Los Angeles and St. Louis, the new guidance has decided to return to the obligation to use indoor masks amid a surge in cases and hospitalizations for COVID-19, which is particularly severe in the South. The country averages more than 57,000 cases and 24,000 COVID-19 hospitalizations daily.
Most new infections in the United States continue among unvaccinated people. However, “breakthrough” infections, which generally cause mild illness, can occur in vaccinated people. Dr. Rochelle Walensky, director of the CDC, said that when early strains of the virus were predominant, infected vaccinated people were thought to have low levels of the virus and not spread the virus very well.
But with delta variants, virus levels in infected and vaccinated people are “indistinguishable” from those in the nose and throat of unvaccinated people, Warensky said.
Data have emerged from 100 samples in the last few days. It has not been announced and the CDC has not released it. But “I’m worried enough that we have to act,” Warensky said.
Vaccinated people “may spread the virus to others,” she said.
For most of the pandemics, the CDC advised Americans to wear masks outdoors if they were within 6 feet of each other.
Then, as vaccination rates soared in April, agencies relaxed guidelines for wearing masks outdoors, and fully vaccinated Americans faced unless they were in a large crowd of strangers. He said he no longer needed to cover it. In May, guidance for fully vaccinated people was further relaxed, allowing them to stop wearing masks outdoors in the crowd and in most indoor environments.
Guidance still required wearing masks in crowded indoor environments such as buses, planes, hospitals, prisons, and homeless shelters, but paved the way for reopening work and other places.
Subsequent CDC guidance states that fully vaccinated people no longer need to wear masks in summer camps and schools.
Although COVID cases, deaths, and hospitalizations have been steadily declining for several months, a more contagious version of the virus, the delta mutant, has begun to spread, especially in areas with low vaccination rates. As a result, these trends began to change in early summer. price.
White House spokesman Jen Psaki said the Delta variant has changed the country’s outlook for COVID-19 since the CDC relaxed masking recommendations.
“That’s their job. Their job is to look at evolving information, evolving data, evolving historical pandemics, and provide guidance to the American people,” said Pusaki.
“What hasn’t changed is the fact that vaccinated people receive a great deal of protection from serious illness, hospitalization and death,” she added.
Some public health experts believe that previous CDC decisions are based on good science, and vaccinated people have a relatively low risk of spreading the virus and are very ill by catching the virus. It shows that the risk of becoming is even lower.
However, these experts were also critical and the honor system was created because Americans did not need to document the vaccination status. They said that unvaccinated people who didn’t want to wear masks in the first place saw it as an opportunity to do what they wanted.
“If all unvaccinated people were responsible and wore masks indoors, we wouldn’t see this surge,” said a former CDC disease researcher who is currently the Dean of the University of Nebraska’s School of Public Health. Dr. Ali Khan said.
Lawrence Gostyn, a professor of public health law at Georgetown University, made a similar conclusion.
“When they (CDC) announced, it was perfectly foreseeable that masking would no longer be the norm, and that’s exactly what happened,” Gostyn said.
He said the CDC might be considered a “flip-flop” because there were no widely recognized changes in science. In addition, it is unlikely to change the behavior of those who most need to wear a mask.
“I don’t think you can get it back effectively,” he said.
Ken Tigpen, a retired respiratory therapist who currently works for a medical device manufacturer, was completely vaccinated and stopped wearing masks in public after the CDC changed guidance in May. But after his work took him to hospitals in Mississippi, Louisiana, Alabama, and Florida, he began to rethink last week after witnessing a medical center flooded with COVID-19 patients. ..
“The delta variant is intense. It’s so contagious that we have to do something to control it,” he said.
“I loved it when I was able to call the hospital. They said,” Today I actually closed the COVID ward or became two COVID patients. ” I’m crazy. “
