Shanghai is a super-large metropolis with a highly developed
globalization . Since the 21st century, Shanghai has experienced several threats of emerging and
imported infectious diseases .
Infectious disease surveillance has been established and developed from single-
disease surveillances to a comprehensive
surveillance network. Integration of clinical and
preventive medicine has been gradually extended, which facilitates the improvement in the
monitoring and
early warning system . In 2020, when the COVID-19
epidemic spread, Shanghai quickly established a prevention and control expert team and a clinical medical expert team to effectively and shortly control local COVID-19
epidemic . In order to improve Shanghai’s capacity to respond to major
epidemics of
infectious diseases and
public health emergencies , the metropolis
will build and improve a three-level
diagnosis and
treatment system for emerging, imported, rare, and unknown
infectious diseases in the next five years. Based on the
big data monitoring platform of medical institutions, Shanghai
will achieve the
intelligence -supported
diagnosis and
treatment of
infectious diseases , and consolidate the cooperation to implement the integration of clinical and
preventive medicine .
