COVID-19: what is next for public health?
First, epidemiological changes, the effectiveness of public health strategies and their social acceptability need to be closely monitored.
Second, continue to strengthen the communication of protection strategies and provide self-protection strategies, including symptom identification and clear treatment guidance, to the general population and the most vulnerable and vulnerable.
Third, at the outbreak center in China, strict source control needs to continue, namely, isolation of patients and those tested positive for novel coronavirus, contact tracing and health surveillance.Strict prevention and control of infection in health facilities and other active public health control measures are in place, with ongoing surveillance and limited interventions in all other locations where outbreaks occur in China.
Fourth, there is a need to continue containment measures in locations outside China where there is transmission between infected persons and contacts, and to conduct in-depth research to provide information on transmission capacity, means of transmission and natural infection history, to report to who on a regular basis and to share data.
Fifth, there is a need for enhanced active surveillance of possible infections in all countries, using case surveillance methods recommended by the world health organization.
Sixth, health systems in all countries need to be ready to anticipate severe infections and disease progression in the elderly and other populations at risk of serious illness, as is the case with seasonal influenza.
Seventh, if a community outbreak has spread, isolation measures should be considered, especially if contact tracing is ineffective, the community is overwhelmed, and resources are used inefficiently.Isolation measures include the removal of public meetings, school suspensions, telecommuting, home isolation, observing the health of symptomatic patients through telephone or online health counseling systems, and providing basic living support, such as oxygen supplies, mechanical ventilators, and ECMO devices.
Eighth, serological tests need to be developed to assess current and previous infections in the general population.
