Abstract
Recent rapid developments in Asian and African countries bring an opportunity of cross-species transmission of pathogens through unprecedented contacts between people and wild animals. Furthermore, increase of global exchanges of people and products facilitates a rapid spread of infectious diseases worldwide. China has an enormous population with diverse ethnic groups within its wide territory; furthermore, it is experiencing very rapid urbanization. These conditions make China a potential epicenter of emerging infectious diseases. One good example is the SARS incidence in 2003. Therefore, it is essential to include China in a network of research groups of infectious diseases. Here we summarize the ongoing collaborations between the Institute of Medical Science, the University of Tokyo, and its Chinese counterparts.
