Evaluating population immunity and infections of influenza, SARS-CoV-2 and other respiratory virus infections: A community-based longitudinal cohort study (EPI-HK study)

The research team at the HKU School of Public Health have been at the forefront of research into COVID-19 . One major question is “how many people have been infected so far”. The HKU team are part of a large consortium of international experts to answer this question in different parts of the world. 

This is a large-scale community-based research study on COVID-19 and other respiratory virus infections such as influenza organized by the School of Public Health, the University of Hong Kong. For a period of 5 years (2020 – 2025), we will monitor the incidence of COVID-19 and other respiratory virus infections in the community, as well as to determine how long immunity will last after infection or vaccination, and the associated protection against infection and severe disease, in adults and children.
