For nearly three years, China has remarkably kept its Covid death toll relatively low. With only about 6,000 deaths among a population of 1.4 billion, China's "zero Covid" policy – characterized by strict lockdowns, widespread testing, and stringent measures – achieved significant success. In contrast, the US, with a population of 330 million, has reported over a million deaths.
Recent weeks, however, have unveiled cracks in this strategy. Parts of the country are witnessing record-breaking case surges, with over 71,000 new cases recorded on Nov. 29 alone. Rising Covid restrictions have led to protests in major cities, an uncommon occurrence in a decade.
With the emergence of the omicron variant, questions regarding the feasibility of maintaining a "zero Covid" approach and the implications of reopening abound. Epidemiologists and public health experts are grappling with these queries and assessing potential responses. Here's an overview of these critical questions and the current understanding.
Is 'zero covid' possible with omicron?
At its core, a "zero Covid" policy aims to halt viral transmission within a country, a challenge amplified by the highly contagious omicron variant. The importation of cases by foreign travelers and subsequent outbreaks pose difficulties, prompting strict entry limitations. When outbreaks occur, a combination of quarantine, contact tracing, and mass testing is used to swiftly suppress the virus.
China's approach and challenges
China's sustained "zero Covid" success relied on stringent movement restrictions and extensive testing. However, omicron's rapid transmission has evaded traditional public health measures such as masking and quarantine.
Although the approach worked throughout most of the pandemic, experts suggest its sustainability wanes as Covid spreads globally. The objective of a "zero Covid" policy is preparation during low case periods, ensuring hospitals can manage surges.
Epidemiologists predict that China's "zero Covid" policy might be faltering, with community transmission potentially exceeding official recognition.
Potential abandonment and complex factors
While there's no official indication of China abandoning its approach, the growing weariness of restrictions and their societal impact poses challenges. The fatigue stems from understanding Covid's mild impact when vaccinated and questioning the necessity of such restrictive measures.
China's population remains incompletely vaccinated, particularly among the elderly. Speculation suggests a surge similar to the US's omicron experience could result in significant ICU admissions and fatalities due to incomplete vaccination coverage.
Uncertain path forward
The unprecedented situation of maintaining viral containment for an extended period adds complexity. To avoid a severe crisis, China may consider a cautious reopening to curtail transmission. China is bolstering its healthcare infrastructure, anticipating a surge in severe Covid cases. As China navigates the uncharted waters of its "zero Covid" strategy, a delicate balance between containment and reopening remains paramount.
