In this seminar, Weijun Yu, senior research officer at the Global Health Institute, delved into cutting-edge research exploring the spread of COVID-19 through the lens of network science and spatial analysis. This one-and-a-half-year observational research project sheds light on the complex mobility patterns and interactions of asymptomatic and symptomatic COVID-19 cases in Hong Kong. Yu explained how the project harnessed innovative methods to reveal the intricate social networks of vulnerable populations and spatial clustering patterns, providing crucial insights for global health strategies.
This event was open to all Georgetown University faculty, students, staff, and affiliates.
This event was co-sponsored by the Center for Global Health Science and Security, the School of Health’s Department of Health Management and Policy, and the Global Health Institute.
