Do you remember when Covid was going to establish China as the world’s dominant power? As late as mid-2021, my inbox was full of assertions that China’s apparent success in containing the coronavirus showed the superiority of the Chinese system over Western societies that, as one commentator put it, “did not have the ability to quickly organize every citizen around a single goal.”

 

At this point, however, China is flailing even as other nations are more or less getting back to normal life. It’s still pursuing its zero-Covid policy, enforcing draconian restrictions on everyday activities every time new cases emerge. This is creating immense personal hardship and cramping the economy; cities under lockdown account for almost 60 percent of China’s G.D.P.

 

In early November many workers reportedly fled the giant Foxconn plant that produces iPhones, fearing not just that they would be locked in but that they would go hungry. And in the last few days many Chinese, in cities across the nation, have braved harsh repression to demonstrate against government policies.

 

I’m not a China expert, and I have no idea where this is going. As far as I can tell, actual China experts don’t know, either. But I think it’s worth asking what lessons we can draw from China’s journey from would-be role model to debacle.

 

Crucially, the lesson is not that we shouldn’t pursue public health measures in the face of a pandemic. Sometimes such measures are necessary. But governments need to be able to change policy in the face of changing circumstances and new evidence.

 

When will the pandemic end? We asked three experts — two immunologists and an epidemiologist — to weigh in on this and some of the hundreds of other questions we’ve gathered from readers recently, including how to make sense of booster and test timing, recommendations for children, whether getting covid is just inevitable and other pressing queries.

 

How concerning are things like long covid and reinfections? That’s a difficult question to answer definitely, writes the Opinion columnist Zeynep Tufekci, because of the lack of adequate research and support for sufferers, as well as confusion about what the condition even is. She has suggestions for how to approach the problem. Regarding another ongoing Covid danger, that of reinfections, a virologist sets the record straight: “There has yet to be a variant that negates the benefits of vaccines.”

 

How will the virus continue to change? As a group of scientists who study viruses explains, “There’s no reason, at least biologically, that the virus won’t continue to evolve.” From a different angle, the science writer David Quammen surveys some of the highly effective tools and techniques that are now available for studying Covid and other viruses, but notes that such knowledge alone won’t blunt the danger.

 

What could endemic Covid look like? David Wallace Wells writes that by one estimate, 100,000 Americans could die each year from the coronavirus. Stopping that will require a creative effort to increase and sustain high levels of vaccination. The immunobiologist Akiko Iwasaki writes that new vaccines, particular those delivered through the nose, may be part of the answer.

 

And what we’re seeing in China is the problem with autocratic governments that can’t admit mistakes and won’t accept evidence they don’t like.

 

In the first year of the pandemic, strong, even draconian restrictions made sense. It was never realistic to imagine that mask mandates and even lockdowns could prevent the coronavirus from spreading. What they could do, however, was slow the spread.

 

At first, the goal in the U.S. and many other countries was to “flatten the curve,” avoiding a peak in cases that would overwhelm the health care system. Then, once it became clear that effective vaccines would become available, the goal was or should have been to delay infections until widespread vaccination could provide protection.

 

You could see this strategy at work in places like New Zealand and Taiwan, which initially imposed stringent rules that held cases and deaths to very low levels, then relaxed these rules once their populations were widely vaccinated. Even with vaccines, opening up led to a large rise in cases and deaths — but not nearly as severe as would have happened if these places had opened up earlier, so that overall deaths per capita have been far lower than in the United States.

 

China’s leaders, however, seem to have believed that lockdowns could permanently stomp out the coronavirus, and they have been acting as if they still believe this even in the face of overwhelming contrary evidence.

 

At the same time, China utterly failed to develop a Plan B. Many older Chinese — the most vulnerable group — still aren’t fully vaccinated. China has also refused to use foreign-made vaccines, even though its homegrown vaccines, which don’t use mRNA technology, are less effective than the shots the rest of the world is getting.

 

All of this leaves Xi Jinping’s regime in a trap of its own making. The zero-Covid policy is obviously unsustainable, but ending it would mean tacitly admitting error, which autocrats never find easy. Furthermore, loosening the rules would mean a huge spike in cases and deaths.

 

Not only have many of the most vulnerable Chinese remained unvaccinated or received inferior shots, but because the coronavirus has been suppressed, few Chinese have natural immunity, and the nation also has very few intensive care beds, leaving it without the capacity to deal with a Covid surge.

 

It’s a nightmare, and nobody knows how it ends. But what can the rest of us learn from China?

 

First, autocracy is not, in fact, superior to democracy. Autocrats can act quickly and decisively, but they can also make huge mistakes because nobody can tell them when they’re wrong. At a fundamental level there’s a clear resemblance between Xi’s refusal to back off zero Covid and Vladimir Putin’s disaster in Ukraine.

 

Second, we’re seeing why it’s important for leaders to be open to evidence and be willing to change course when they’ve been proved wrong.

 

Ironically, in the United States the politicians whose dogmatism most resembles that of Chinese leaders are right-wing Republicans. China has rejected foreign mRNA vaccines, despite clear evidence of their superiority; many Republican leaders have rejected vaccines in general, even in the face of a huge partisan divide in death rates linked to differential vaccination rates. This contrasts with Democrats, who have in general followed something like New Zealand’s approach, if much less effectively — restrictions early on, relaxed as vaccination spread.

 

In short, what we can learn from China is broader than the failure of specific policies; it is that we should beware of would-be autocrats who insist, regardless of the evidence, that they’re always right.
