Severe pediatric infectious diseases such as pneumonia, diarrhea and dengue are the main cause of under-five mortality and morbidity globally. These can be prevented by preventive measures such as vaccines, and early recognition and treatment of risk groups. We conduct population based cohort and intervention studies to provide better preventive measure and treatment for sever pediatric infectious diseases in the tropics.
