Chemotherapeutic malaria control operation by single dose of Fansidar plus primaquine in North Sumatra, Indonesia.

Author information

Department of Parasitology, Okayama University Medical School, Japan.


Selective age group treatment and village scale chemotherapeutic malaria control operation were carried out in east-coast villages in North Sumatra, Indonesia in 1987/1988. A single dose of Fansidar plus primaquine was adopted as the drug regimen to cut the transmission of malaria at the gametocyte stage. After the treatment on day seven, the gametocyte positive rate was reduced to only 2.7% in 72 Plasmodium falciparum gametocyte carriers. A significant reduction of P. falciparum prevalence in the community was observed after successive selective age group treatment in primary school, however P. vivax prevalence persisted. Village scale active case detection was carried out by one health center staff and two village health volunteers. After eight months P. falciparum prevalence was reduced from 14% to 1%. As the result of the chemotherapeutic control activities covering high-prevalence villages in the coastal area, malaria prevalence in 1988 became very low, as compared with the status in 1985/1986.
