Abstract

Malaria is a major health problem in many developing countries including Indonesia. The purpose of this study was to investigate the socio-demographic characteristics and geographic distribution of malaria cases in Bangka District, Bangka-Belitung Island Province, Indonesia. Bangka District is a malaria endemic area of Indonesia. We analyzed the epidemiological data of all reported malaria cases during 2008-2012 in Bangka District. Of the 4,756 malaria-confirmed cases reported during the study period, 3,234 (68. 0%) were among persons aged ≥15 years, 1,024 (21.5%) were among persons aged 5-14 years and 498 (10.5%) were among persons aged <5 years. Malaria cases were primarily located along the sea coast and less frequently in inland. Malaria cases were found not only among the local population but also among migrant workers. The monthly incidence of reported malaria cases in the study population ranged from 0.06 to 1.06 per 1,000 person-months. The cases were mostly due to Plasmodium vivax (57.1%) followed by Plasmodium falciparum (40.2%). Plasmodium falciparum was more common among migrant workers while Plasmodium vivax was more common among the local population (Odds ratio 1.2; p=0.03). The main transmission vector found in the coastal area was Anopheles sundaicus. An. letifer and An. barbirostris were found inland. We identified “malaria hot-spots” in the study area using a Geographic Information System. The results of this study will contribute to the malaria control program.
