The NUH Division of Infectious Diseases was formally established in 2003 by Professor Paul Tambyah. After completing his training in Wisconsin, Professor Tambyah returned to Singapore, establishing himself as the first and only Infectious Diseases (ID) consultant at NUH. Professor Dale Fisher was recruited as a locum which occurred by remarkable coincidence at the precise onset of the SARS outbreak in March 2003. In December 2004, Professor Fisher relocated from Darwin, Australia to join Professor Tambyah and a then young trainee named Dr Louis Chai. Over the past 15 years, the Division has grown beyond its three founders and now includes 13 consultants, a resident physician and 2 senior residents. Beyond our doctors, we have strong multidisciplinary support from microbiologists, nurses, pharmacists, research assistants, epidemiologists, medical social workers, administrators and other partners. The Division's achievements, provided by individual members and collectively as teams, can be seen in its trainee alumni, its clinical contributions and its research output. Each has extensive collaborations and influences not only locally but across the world.
