Guidelines for COVID-19 Epidemiological Investigations

The Chinese Center for Disease Control and Prevention released the guidelines for COVID-19 epidemiological investigations to further improve epidemiological investigations of COVID-19 cases and help control spread of the virus.

The guidelines cover the investigation of COVID-19 suspected cases, confirmed cases, asymptomatic infected individuals and clusters of cases, helping to find the sources of infection and trace and analyze transmission characteristics of COVID-19 cases and clusters of cases.

Upon receiving a report of one or more COVID-19 cases, the county- or district-level disease control and prevention agency should complete an initial epidemiological investigation within 24 hours, according to the guidelines.
