COVID-19 News: The sudden termination of China's stringent COVID-19 control measures in December 2022 has raised significant concerns about the resulting surge in infections and its impact on public health. A recent study conducted by the federally funded Fred Hutchinson Cancer Center in Seattle-USA sheds light on the consequences of China's decision, revealing a potentially dire outcome. The study, based on an analysis of mortality data from various sources, suggests that China's abrupt end to its COVID-19 restrictions may have led to nearly 2 million excess deaths within just two months, from December 2022 to January 2023.

The zero-COVID policy that China had in place for three years was characterized by aggressive measures such as mass testing, stringent quarantine protocols, and persistent lockdowns to swiftly contain any outbreak. This strategy helped maintain low COVID-19 incidence and mortality rates in the country during the initial years of the pandemic. However, the decision to abandon this policy resulted in a massive surge in COVID-19 cases, hospitalizations, and deaths according to initial local COVID-19 News sources in China that were later banned, censored and taken down by Chinese authorities.
The study's findings are particularly concerning because they significantly surpass the official estimates provided by the Chinese government. While the government reported approximately 60,000 COVID-19 deaths in hospitals during the same period, the research suggests that the actual number of excess deaths related to the policy shift was far higher.
The study's results underscore the importance of transparent and accurate reporting of COVID-19 data, especially during critical junctures in the pandemic.
To conduct this study, researchers employed an interrupted time-series design, analyzing published obituary data from universities in China and search engine data from Baidu, a popular Chinese search engine. The research covered the period from January 2016 to January 2023 and focused on individuals aged 30 and older. By extrapolating the data from specific regions to the entire country, the study estimated that there were around 1.87 million excess deaths among this demographic group during the first two months following the end of the zero-COVID policy.
One of the study's key findings was the strong correlation between the search engine queries related to mortality and the actual mortality data. This correlation allowed the researchers to estimate excess mortality in regions not covered by their initial data sources.
The excess deaths were observed across all provinces in mainland China, with the exception of Tibet. This distribution highlights the widespread impact of the policy change on public health across the nation.
Notably, the excess deaths were more prevalent among older individuals. This pattern aligns with the general understanding that COVID-19 disproportionately affects older age groups, who tend to experience more severe outcomes if infected. The study also identified a correlation between the policy change and a significant increase in all-cause mortality, suggesting that the surge in COVID-19 cases had broader health implications beyond di rect COVID-19-related deaths.
The study's implications extend beyond the realm of public health statistics. They underscore the complexity of decision-making in response to a pandemic and highlight the need for a balanced approach that considers both the immediate impact of policy changes and their potential long-term consequences.
While stringent measures can help contain the spread of the virus, abrupt relaxation of these measures can lead to unforeseen negative outcomes, as demonstrated by the surge in excess deaths observed in China.
This research also highlights the importance of empirical data in informing policy decisions. Model-based forecasts, while valuable tools, lack the robustness and accuracy of empirical data collected from real-world situations. The study's empirically derived estimate of excess deaths provides a valuable benchmark for policymakers and public health experts to understand how sudden changes in COVID-19 transmission dynamics can impact population mortality.
Furthermore, the study's findings shed light on the ongoing challenges posed by new variants of the virus. The emergence of the Omicron variant, nicknamed EG.5 or "Eris," underscores the continued threat of the virus and its potential to cause surges in infections even after prolonged periods of control. This variant's rapid spread and dominance in multiple regions of China further emphasize the need for adaptive and data-driven responses to evolving COVID-19 strains.
In conclusion, the study's results contribute significantly to our understanding of the consequences of China's decision to end its zero-COVID policy. The estimated 1.87 million excess deaths within two months of the policy shift underscore the intricate relationship between COVID-19 control measures, infection rates, and population mortality. The study emphasizes the importance of evidence-based decision-making and transparent data reporting in managing a pandemic. As the global community continues to navigate the challenges posed by COVID-19 and its variants, lessons from studies like these can inform strategies that prioritize both immediate containment and long-term public health outcomes.
The study findings were published in the peer reviewed journal: JAMA Network Open.
