The CDC’s proposal to stop football, a band in almost every school in the United States, is called “unrealistic”

“As we say in Tennessee, that dog is not out of the woods,” said Schaffner, an infectious disease specialist at Vanderbilt University Medical Center.

In recent weeks, the agency has been criticized for giving instructions that were confusing or seeming reluctant. In this case, the criticism is different; the concern is that CDC employees, while diligent, intelligent, and well-meaning, do not always consider whether Americans – or even can – follow their advice.

CNN asked CDC director Dr. Roche Walensky about two guidelines. In a statement, Walensky said the agency “prioritizes researchers over athletics because of the increased risk associated with some out-of-school sports. When followed, our school guidance has been incredibly effective. In the fall, 99 percent of schools were able to stay open during COVID’s strong delta.”

Schaffner and others say part of the problem is that CDC researchers are sometimes stuck in a bubble.

“You have nerds – literally science nerds – who write these things,” said Dr. Otis Brawley, who worked with the CDC under the guidance of Cancer while chief physician of the American Cancer Society from 2007 to 2018.

“I really feel compassion for the people at the CDC,” he said. “They are cursed if they do, and they are cursed if they do not.”

CDC School Guidance

The CDC cites football and wrestling as examples of high-risk sports, saying “non-high-risk activities are those where exhalation increases, such as activities involving singing, shouting, a band, or training, especially indoors.”

Paul Imhoff, president of The School Superintendents Association, told CNN that while schools have put a lot of effort into curbing the spread of Covid-19, he doesn’t know of schools that have canceled activities such as football, a band or a choir. He said such activities are “important to students’ mental health.”

“Schools make decisions to form and wrestle with a choir and band, so it’s about our children being healthy in every way. I think everyone is doing their best to take care of the whole child,” said Imhoff, the school principal in Ohio.

In a statement to CNN, Walensky said the CDC “developed the guidance of our school knowing that school officials, teachers and parents were waiting for us at the CDC to get their children back into an enriching classroom environment, and it was paramount to get our children back to school safely,” adding that ” vaccines are available for school-age children, which adds a second layer of protection and improves school guidance. ”

However, Schaffner questioned why the CDC would advise schools to cancel lessons that involve shouting when children shout regularly.

“I could take you by the hand and say, ‘Let’s walk through three high schools.’

CDC Insulation Guidelines

The Computational Epidemiology Lab at Boston Children’s Hospital estimates that more than 80 percent of Americans have at least one of the diseases listed on the CDC, according to an analysis by the group for CNN.

Schaffner questioned the practicality of avoiding 80% of the people around you.

“How do you know if people have heart disease or diabetes? How should it be diagnosed? Do you identify any pregnant, sickle cell or former smokers?” he said and named some conditions in the CDC’s list of ones to avoid.

When Walensky was asked for advice at a news conference, Walensky said the agency asked people to “avoid their family members or others who may be immunocompromised, avoid visiting their grandmother or nursing home.”

“Round red tomatoes”

Looking at the CDC’s school and isolation guidelines, Glen Nowak recalls the foodborne disease epidemic of 2008 when he was CDC’s head of media relations.

It was unclear what had caused people to get sick, but one of the possible culprits was tomatoes, so Nowak said the agency’s researchers wanted to urge Americans to stop eating tomatoes.

Nowak says he told researchers that this was quite extensive because tomatoes are a very common food. He says he asked his colleagues to be more specific – was there a particular type or source of tomatoes that Americans should avoid?

Nowak said when he worked at the CDC from 1999 to 2012, researchers repeatedly developed guidelines without thinking about the next step: Is it possible to follow the advice we have written? If so, what exactly should someone do?

“It was an ongoing challenge. It came up in many circumstances,” said Nowak, director of the University of Georgia’s Center for Health and Risk Communication.

“It’s really hard for scientists and experts to see the world through the lenses of everyday people,” he added.

Replacing the lens

One way to change the lens is to seek feedback from outside groups, but it has been more difficult during a pandemic when the agency has had to act faster. Spokesmen for the Property Management Association and the National Association of Secondary School Directors said they were not contacted by the CDC to negotiate the direction of school sports and out-of-school activities.

The federal health authority, which is familiar with how the CDC is developing its guidelines, said the agency should also make better use of its own communications experts.

“There is simply no place for the communicator when it comes to developing guidelines,” the official said, adding that CDC’s communications experts “consider whether the guidance to be developed is really practical.”

The official asked to speak anonymously because they did not have the authority to speak on the matter.

Brawley pointed out that the pandemic has posed unusual challenges in providing guidance.

He said that under normal circumstances, experts first gather all the relevant research on a particular topic and then discuss – sometimes for months – what would be the best advice to the public, and also consult outsiders to get their input.

“When I was at the American Cancer Society, when we sat writing instructions for lung cancer, it took almost a year for a group of 14 people to come up with a wording. “The CDC doesn’t have time to do that.”

Brawley, now a professor at Johns Hopkins University, said there was an alternative to CDC guidelines. For example, if schools are not prepared to cancel a football or choir, the CDC could only explain that they are risky activities without directly advising them.

He said it would be important to explain the research, which shows that these are risky activities that the CDC is not doing on its site now.

“I would include research because I have a feeling that a large percentage of American lay people don’t understand how we came up with these rules. This isn’t just a couple of people in Atlanta who came up with these in their own hands. The rules are based on real observations in real populations,” he said.

But he added that the CDC would likely continue to be criticized for its instructions, at least by some people.

“It’s not possible for the CDC to win,” he said.
