From SARS to the Omicron variant of COVID-19: China's policy adjustments and changes to prevent and control infectious diseases

Luo M, Liu Q, Wang J, Gong Z


The COVID-19 pandemic has been the biggest public health crisis in a century. Since it was initially reported in 2019, the duration and intensity of its impacts are still in serious question around the world, and it is about to enter its third year. The first public health revolution failed to achieve its ultimate targets, as previously contained infectious diseases seem to have returned, and new infectious diseases continue to emerge. The prevention and control of infectious diseases is still a public health priority worldwide. After SARS, China adjusted a series of its infectious disease policies. In order to ensure the effectiveness and implementation of prevention and control interventions, the government should integrate the concept of public health. Perhaps we need a global public health system at the government level to fight the potential threat of infectious disease. This system could include multifaceted strategies, not just specific prevention and control interventions, and it could also be a comprehensive system to ensure unimpeded communication and cooperation as well as sustainable development.
