The unit’s strategic aim is to have a positive and significant impact on global health and, in particular, the prevention, diagnosis and treatment of infectious diseases. This is being achieved via an integrated long-term research programme, contributions to training, the scientific literature, national and international meetings and membership of national and international committees. Priority is given to health issues important to the hospital, the city and the whole of Vietnam. All work is intended not only to benefit the patients seen daily at HTD, but also to help improve patient care throughout the country.
