China's loosened COVID-19 policies – following years of aggressive lockdowns and quarantines – have left the country vulnerable

China’s initial reaction to COVID-19

Public health campaigns and control of emerging disease in China are entirely reliant on and directed by the government, which promotes health both for the good of the people and the nation^[14]. When COVID-19 emerged, the Chinese government was quick to institute mask-wearing policies and testing regimens, and it locked down the city of Wuhan and the surrounding region^[15] where the coronavirus originated. With only the aid of these nonpharmaceutical interventions^[16], the Chinese government was very successful in containing the spread of COVID-19 after the initial wave hit Wuhan.

From the time China started recording cases in late December 2019, until the government ended its initial period of lockdown in April 2020, the government documented ^[17] 82,000 cases of COVID-19 and just over 3,300 deaths. Though not officially called a zero-COVID policy at the time, the control measures were born out of a goal of eliminating COVID-19^[18] from the country.

Ramping up zero-COVID

Life returned to normal in China after the initial wave of COVID-19 ravaged Wuhan. For most of 2020 and the first half of 2021, Chinese people were out and about^[20] in shopping malls, restaurants and bars.

During this same period, the coronavirus was rampaging across the U.S, Europe and other regions of the world, leading many health experts to say that the lockdowns in China, though brutal, were successful^[21]. Between May 2020 and August 2021, people in China saw COVID-19 as a distant threat^[22] and supported the government’s actions.

The situation changed in August 2021 when the Chinese government officially adopted what it calls the “Dynamic zero-COVID^[23]” strategy to combat the new delta variant. This strict prevention policy included provisions for mass lockdowns aimed at eliminating^[24] the disease in a particular region, even if just a small number of cases were found.

China ramped up enforcement of the policy^[25] as the 2022 Winter Olympics approached. A single case^[26] could trigger a massive lockdown where the government would severely limit people’s movement and enforce quarantines, as occurred several times in Shanghai Disney. In some instances, people were held in stores or office buildings for several days^[27] after exposure to an infected person.

Summer and fall 2022 were relatively quiet, with only around 1,000 confirmed infections per day. But since early November 2022, COVID-19 cases in China have climbed steadily^[28], with more than 35,000 new cases detected per day^[29] in the first week of December.

What happens next?

As of early December, COVID-19 rates in China were still relatively low compared to many places, including the U.S.^[31]. But China faces some unique challenges thanks to low levels of immunity in the population and a disease control strategy that prioritized nonpharmaceutical interventions like mask-wearing, social distancing and frequent testing over vaccine administration^[32].

To date, 90% of the population in China has been vaccinated^[33]. Older people have been more reluctant, though, and only 66% of those over 80^[34] have received two doses of a vaccine. A further concern arises from studies indicating that China’s vaccines may not be as effective as the mRNA vaccines^[35] used in the West. So far, China has not been willing to import^[36] and administer Western mRNA vaccines.

In addition to concerns over vaccination, the zero-COVID policy has, to a large extent, successfully suppressed the coronavirus in China. The result is that since most people have not been exposed to the virus, they have not had a chance to develop immunity. This has likely left the country very susceptible^[37] to a large outbreak.

There is also a social dimension to the problems facing China today. Recurring lockdowns^[38] over the past year have damaged the economy and lessened peoples’ patience^[39] with restrictive policies. Despite government efforts to limit access to outside information^[40], people in China are learning that most other countries are functioning normally. Maintaining stringent zero-COVID policies has become increasingly difficult, as they wear on a populace^[41] that wants life to return to normal.

The Dec. 7 announcement to ease COVID-19 restrictions is a continuation of a trend a few weeks in the making, but has been seen by many as a response to the widespread protests^[42]. Testing centers are closing^[43] and infected people are now allowed to quarantine at home^[44] for the first time since the pandemic began. The digital health passes, issued to people who tested negative through daily PCR tests, are also no longer required^[45] to enter public places.

In much of the world, COVID-19 has followed that natural trajectory^[46] of a pandemic. The story is different in China. The relaxation of zero-COVID policies may bring China more in line with the rest of the world in terms of what the people there can do, but the virus also gets a chance to run its natural course now that government actions will not suppress the spread. It is likely that in the coming months, the Chinese people will face the pain and suffering that many other places experienced in 2020 and 2021.
