For COVID-19, what are the priorities of normalized prevention and control strategies?

The COVID-19 pandemic has ravaged the world for three years. Most countries have adjusted policies and strategies in response to the burden of COVID-19. The severity of COVID-19 seems to be diminishing as the case fatality rate has declined and the number of vaccinated people has increased markedly. Given the large population worldwide, we need to pay attention to the continuing COVID-19 burden. Globally, the number of cases remains at a certain level, and the number of cases is still increasing in China. We also need to deal with shortages of medical resources, antipyretics, and home nursing facilities. SARS-CoV-2 will coexist with humans for a long time, and predicting viral mutations and pandemic trends will be difficult. The reform of the whole public health system is imperative. A comprehensive surveillance system should be created to determine the proportion of various pathogens and to guard against mixed infections of respiratory infectious diseases. A comprehensive response mechanism, including preventive measures and medical treatments, should be created as soon as possible to monitor the status of the epidemic and to deal with the long-term health burden of SARS-CoV-2.
