TAIPEI, Taiwan — The sweeping “zero-tolerance” strategy that China has used to keep COVID-19 case numbers low and its economy functioning may, paradoxically, make it harder for the country to exit the pandemic.
Most experts say the coronavirus isn’t going away and could eventually become, like the flu, a persistent but generally manageable threat if enough people gain immunity through infections and vaccines.
In countries like Britain and the U.S., which have had comparatively light restrictions against the omicron wave, there is a glimmer of hope that the process might be underway. Cases skyrocketed in recent weeks but have since dropped in Britain and may have leveled off in the U.S., perhaps because the extremely contagious variant is running out of people to infect.
Some places already are talking about easing COVID-19 precautions.
But China, which will be in the international spotlight when the Beijing Winter Olympics begin in two weeks, is not seeing the same dynamic.
The communist government’s practice throughout the pandemic of trying to find and isolate every infected person has largely protected hospitals from becoming overwhelmed and staved off the deaths that have engulfed most of the world.
But the uncompromising approach also means most people in China have never been exposed to the virus.
At the same time, the effectiveness of China’s most widely used vaccines has been called into question. New studies suggest they offer significantly less protection against infection from omicron, even after three doses, than people get after booster shots of the leading Western vaccines.
Together, those factors could complicate China’s effort to get past the pandemic.
Experts say that if the country of 1.4 billion people were to relax restrictions, it could face a surge similar to what Singapore or Australia experienced, despite a highly vaccinated population.
“China’s susceptibility to outbreaks is likely to be more because most people have not been exposed to the virus due to the stringent measures that were put in place, thus lacking hybrid immunity, which is supposed to prove better protection than vaccination alone,” said Dr. Vineeta Bal, an immunologist at the Indian Institute of Science Education and Research.
“It is risky for China to reopen right now because omicron is spreading globally, and even if the variant doesn’t cause major illness, it’ll spread like wildfire,” she added.
Dali Yang, a professor who studies Chinese politics at the University of Chicago, said, “It’s a big challenge, for leaders, especially their rhetoric on saving lives. How do you justify opening up and then having tens of thousands of people dying in the process?”
Chinese President Xi Jinping has cited China’s approach as a “major strategic success” and evidence of the “significant advantages” of its political system over Western liberal democracies.
The world’s most populous nation was the only major economy to grow in 2020, and it accounted for a fraction of global deaths and infections.
As part of the country’s tough-minded strategy for keeping the virus at bay, residents in Chinese cities must display their infection status on a government-monitored app to enter supermarkets, offices or even the capital.
But weeks ahead of the Olympics, omicron is testing this approach with outbreaks in the southern province of Guangdong, as well as Beijing.
