A Public Health Seminar, delivered on May 2, 2011 by Dr. Yi Tan, "Tany".

This presentation will focus on three molecular epidemiological studies on common viral infectious diseases: Human immunodeficiency virus (HIV) infection, Influenza, and Hepatitis C virus (HCV) infection. The first, a molecular epidemiological study of HIV in Macao, a city in southern China, showed multiple introductions and high genetic diversity of HIV strains for an extended period of time. The second study, involving phylogenetic analysis of H1N1/09 influenza sequences collected from three cities (Huston, Milwaukee, and New York City) in the US suggested different epidemiological patterns for the spring and fall waves of the H1N1/09 influenza pandemic. For the last study we found that HCV 6a strains had spread rapidly around 1980s in southern China using phylogenetic analysis with epidemiological data.

Dr. Yi Tan (Tany) is a post-doctoral fellow at the NIH Fogarty International Center for Advanced Study in the Health Sciences. She works on the phylogenetic analysis of influenza virus genetic sequences, hoping to trace the transmission patterns of epidemics and gain a better understanding of viral evolution. Dr. Tan earned her doctorate at the Chinese University of Hong Kong in Ph.D. in 2008. She pursues collaborative research on the molecular epidemiology of infectious diseases, including HIV/HCV, influenza, HPV, and other viruses. Recently Dr. Tan helped implement new research collaborations between the Fogarty International Center and research Institutes in Southern China to investigate seasonal influenza epidemics and the impact of the 2009 A/H1N1 pandemic in subtropical regions.
