The incidence of severe malaria and malaria-specific mortality were investigated in a hospital, for miners and their families, at Tensa in the Sundergarh district of Orissa state in India. Tensa lies in area where malaria (predominantly caused by Plasmodium falciparum) is hyper-endemic. The hospital records for 1995--1999 showed that, although annual admissions for malaria increased over the study period, there were very few admissions for severe, complicated malaria and no reports of malaria-specific deaths. Most of the patients who had been admitted with cerebral malaria either came from areas around but not within the town of Tensa or were recent arrivals in the town. It appears that the outcome of malaria is influenced not only by the intensity of local transmission (which affects the immunological status of the human hosts) but also by social factors such as the education and health-seeking behaviour of the local population and the health-care facilities available. The low incidence of severe malaria observed in Tensa was probably the result of patients presenting early in the course of their illness and taking antimalarial treatment, iron supplementation and supportive therapy at the appropriate times.
