On 8 January 2023, after 3 years of pandemic control, China changed its management of COVID-19, applying measures against class B infectious diseases instead of Class A infectious diseases. This signaled the end of the dynamic zero-COVID policy and the reopening of the country. With a population of 1.41 billion, China’s reopening policy during the COVID-19 pandemic has been characterized by a scientific, gradual, and cautious approach. Several factors contributed to the reopening policy, including an expansion of healthcare capacity, the widespread promotion and uptake of vaccination, and improved prevention and control mechanisms. According to the latest report from the Chinese Center for Disease Control and Prevention, the number of hospitalized COVID-19 patients in the country reached a peak of 1.625 million on January 5, 2023, and has since continued to decline. As of February 13, the number decreased to 26,000: a reduction of 98.4%. Thanks to the efforts of healthcare workers and society as a whole, the country managed to get through the peak of the epidemic in a stable manner.
