説明

A mass blood examination was carried out in a coastal village of Perupuk, Asahan Regency, North Sumatra, Indonesia in August 1982. The parasite rate in all ages revealed remarkably high (44%). This was caused by an explosive outbreak of Plasmodium falciparum malaria. The parasite rate in young children (0-9 years) was very high around 60% whereas low less than 20% in adult (over 34 years). This indicates a possibility of outbreak of malaria mostly in children posing public health subject in a village of tropical rural area. Gametocyte carriers of P. falciparum were detected only in the age group less than 25 years. The high parasite density of P. falciparum with both asexual form (more than 1, 000 ring forms/mm3) and gametocyte (more than 100 gametocytes/mm3) was detected only in the age group less than 12 years. Falciparum malaria of high intensity repeatedly occurs mostly in younger age group in Anopheles sundaicus breeding coastal area in north Sumatra. A possible control method aiming at gametocyte carrier of young age group is discussed.
