Reflections on the dynamic zero-COVID policy in China

The coronavirus disease 2019 (COVID-19) pandemic has posed a serious threat to global healthcare and economy. In order to curb its spread, China adopted the dynamic zero-COVID policy, aiming to diagnose and isolate cases and close contacts as soon as possible. However, there is a controversy about the impact of isolation measures on social order, including the economy, personal employment and public mental health. Therefore, this review discusses and analyzes in detail the advantages and challenges of implementing dynamic zero-COVID policy. Although this public health policy might cause a shock to the economy in the short term, China still achieved a continued healthy economic performance with stable unemployment and strong export growth. Moreover, the rates of infection and mortality in China were lower than those in the United States and the European Union. However, due to the high transmissibility and low pathogenicity of the Omicron variant and prolonged lockdown-induced psychological damage, people questioned the effectiveness and necessity of this policy. Now that China has adjusted its policy in a timely manner, but many problems still remain unsolved. Some practical suggestions in terms of mental health, vaccine development, drugs supply, and economic recovery are put forward at the end of our paper to minimize negative impacts and provide a reference for future efforts.
