抄録

The blood and spleen examination for malaria was carried out in six villages (Desa) of Asahan district (Kabupaten), North Sumatra from February 1980 to March 1981. In general, parasite rate proved to be low (average 2.0%) in this area and both species of Plasmodium vivax and P. falciparum were detected. Besides this, interesting aspects of malaria endemic in this area were revealed. First, positive cases were found only in four villages bordering the sea, and, again, malaria endemic area was restricted to a few subvillages (Lorong) close to the coast in each village. Secondly the regular survey perfomed in Lorong I and II of Desa Perupuk, one of six villages, at intervals of a month showed that the active transmission of malaria took place during the dry season from January to July but the transmission became inactive during rainy season from August to December. The role of Anopheles sundaicus, which was determined as a main vector, in the limitation of endemic area and in the seasonal fluctuation of transmission was discussed.
