Health code is the symbol of the residents' medical and health service promoted and implemented by the state, which brings together the data of residents' electronic health records, inpatient and outpatient records, drug purchase records and so on. On the basis of the health code, the Provincial Digital Office and Hubei (Wuhan) and other epidemic-prone areas entered the Fujian personnel information database, the national database of confirmed and suspected cases, the national database of close contacts, and the relevant basic databases of health, medical insurance and public security in our province for docking verification, and generated the "Fujian Health Eight Codes" in real time.
