Impact of non-pharmaceutical interventions on COVID-19

New research co-authored by Xihong Lin, professor of biostatistics at Harvard T.H. Chan School of Public Health, provides insight into the epidemiological features of COVID-19 and the impact of non-pharmaceutical interventions, such as a city quarantine and social distancing, on the spread of the disease in Wuhan, China.

Professor Lin discussed the new research in a virtual seminar on March 13, 2020. The research, conducted in collaboration with colleagues in China, examined individual-level data on 25,961 lab-confirmed COVID-19 cases reported through February 18, 2020. It was published March 6, 2020 on medRxiv, a non-peer-reviewed platform.

In their article, the authors wrote that “aggressive disease containment efforts, including isolation of the source of infection, contact tracing and quarantine, social distancing, and personal protection and prevention, have considerably changed the course of Covid-19 outbreak in Wuhan, when there was neither effective drug nor vaccine for this new infectious disease with high transmission.”
