Abstract:
Objective To explore main problems existing in current infectious disease surveillance system and to propose some primary considerations on the establishment of a full-coverage sentinel and multi-symptomatic infectious disease surveillance system in China to meet the growing demand for surveillance and prevention of infectious disease epidemic.
Methods Literatures relevant to new (major) infectious disease surveillance and early warning published from 2000 through 2021 were systematically searched via China National Knowledge Infrastructure (CNKI), official websites of international organizations, and Baidu Scholar.
Results Based on inductive generalization of 78 literatures retrieved, a theoretical infrastructure was proposed for the full-coverage sentinel and multi-symptomatic infectious disease surveillance system to be constructed. The suggested system should be operated effectively at five-regional level (country, province, municipality, county, and township); the system′s sentinels should include medical institutions, grassroots units, departments responsible for surveillance among migrant populations and a big data management center is also to be constructed for the system. Early clinical and social symptoms of new (major) infectious diseases should be monitored comprehensively across whole country.
Conclusion The construction of full-coverage sentinel and multi-symptomatic surveillance system for new (major) infectious diseases should follow the principles of unified planning, nationwide networking, resource sharing, and effectively operating at ordinary times and in emergency.
