Dr Sean Hsiang-Yu Yuan is an assistant professor in the Department of Biomedical Sciences, City University of Hong Kong, leading the Infectious Disease Modelling Group. He received his PhD at Duke University and worked on infectious disease epidemiology at the MRC Centre for Global Infectious Disease Analysis, Imperial College London.
Mathematical modelling suggests Hong Kong is at a critical point in the fight against Covid-19. The city needs more intensive care beds. To help the contact tracing process, people could go out less and keep a note of where they have been.
