It’s a tough blow for Americans that the CDC has more or less urged us to cancel Thanksgiving this year, but good news for the world that the agency is back in the driver’s seat when it comes to public messaging on the pandemic.

Without the CDC’s grounding influence, advice about the pandemic has been divisive and confusing. The most popular news stories on social media are meant not to inform, but to generate outrage. That’s diverted far too much focus to joggers, beach-goers and protesters.

Contact tracing studies are showing the disease is being spread primarily by people gathering indoors in private settings — at weddings, baby showers, birthday parties and holiday dinners. When people are with family and friends, they feel comfortable gathering closer for longer, which makes disease transmission more likely.

It’s too bad the new Thanksgiving guidelines came so late, after many people made plans. But the change was necessary. In most parts of the U.S., the odds are higher than ever that someone at a Thanksgiving gathering unknowingly has the virus. And it’s only within the last couple of weeks that the situation has gotten this dire: New confirmed cases were 74,000 on November 1 and 187,000 on November 19.

It’s the nature of an exponentially expanding disease that it can move slowly at first and then suddenly start accelerating. “Public health guidance has to evolve too,” says Harvard epidemiologist William Hanage. “The risks of infection now are very different from what they were in, say, August, and as a result public health advice has to move with it.”

And Thanksgiving dinners tend to bring generations together in a way that other sorts of social events don’t. While any Covid patient can get sick enough to need hospitalization, people over 70 are vastly more likely to end up in a hospital, an ICU, or the morgue.

The CDC could do even better, though. They shouldn’t just tell people what not to do, but why. People are less likely to follow rules that seem arbitrary. We also resent rules that seem concocted to make politicians look like they’re doing something, like travel restrictions and curfews. When the CDC makes a recommendation, it needs to explain why following it would likely keep people from being hospitalized or dying from Covid-19. What you want to do, Hanage says, is help people understand how the disease is spreading and what to do to prevent it.

That should mean a newfound focus on limiting social contacts. The reality is that people are unlikely to wear masks at social gatherings. And you can’t wear a mask while eating. Most Americans have gotten the message that all would be fine if everyone wore a mask in public. But talking face-to-face with others, says Hanage, is a much more likely disease-spreading activity than, say, passing on the street. And so it’s been private gatherings that are driving the current surge.

Another promising sign: The CDC’s Thanksgiving message also showed an embrace of harm reduction, not total abstinence. That means focusing on the biggest threats and not browbeating people over activities very unlikely to cause harm. There would be less pandemic fatigue if more people listened to experts such as Harvard’s Julia Marcus, who warned against shaming people for low-risk activities such as going to the beach or letting kids play in playgrounds.

The new CDC guidelines make it clear that the worst possible scenario is one in which big, multi-generational groups take buses and trains from far-off points to meet up for a long indoor dinner. The guidelines suggest, correctly, that that outdoor gatherings are less risky.

One reason fatigue is setting in is that media coverage has focused as much attention on small risks as big ones, and kept everyone on red alert for months when many should have been at yellow — ready to respond if things got more dangerous.

One Iowa woman told the Wall Street Journal how she stayed inside for months, even though there were very few cases in her area. By fall, when cases there were extremely high and the risk vastly worse, she couldn’t take it anymore. She ended up in a bar with friends … and then in a hospital room.

Most critically, the CDC guidance needs to reflect the kind of humility and transparency that makes scientists worthy of our trust — admitting they might have had some things wrong early in the pandemic, when they knew less. Scientific understanding of this pandemic is a moving target. Changing guidance in response to new events or evidence should build public trust instead of eroding it.
