What is always necessary throughout efforts to prevent and control COVID-19 and other infectious diseases? A physical containment strategy and public mobilization and management.

The COVID-19 pandemic continues to ravage the world. As many countries have entered the postpandemic period, current efforts to prevent and control COVID-19 have gradually been normalized in many countries. Although the focus is on vaccines to achieve herd immunity, conventional physical containment strategies should be reassessed as part of efforts to prevent and control infectious diseases. Continued respiratory protective measures such as social distancing and the wearing of masks have been extensively accepted by the public in most countries. A point worth noticing is that the activities of influenza and other respiratory diseases have decreased as these strategies have been implemented. Public mobilization and large-scale campaigns to promote health are also important to interrupting the transmission of pathogens. A good example can be found in the achievements of China's Patriotic Public Health Campaign. These practices underscore the importance of enhancing physical containment strategies and public mobilization and management, with support from the legal system, to respond to any potential emerging infectious diseases.
