Dr Tao Dong tells us about her collaborations in China on infections such as HIV, flu and Hepatitis B. Due to its population size, China is a major contributor to infectious disease worldwide - large-scale patient cohorts, well-established infrastructure, and government funding also make research more accessible. Dr Tao Dong's research interests include antigen-specific T cell responses in human virus infections and their contribution to the consequences of the disease. Dr Dong is currently collaborating with Chinese hospitals to research human virus infections such as Hepatitis B, influenza, and Hepatitis C/HIV co-infection.
