From March 1981 until August 1985, 79 children suffering from falciparum malaria were treated with chloroquine upon admission to the Department of Child Health, Medical School Sam Ratulangi University/Gunung Wenang General Hospital, Manado. Twenty-one out of 79 patients were within range of the criteria of resistance as established by WHO: Standard field test or 7 days test. Six (28.6%) out of 21 patients belonged to resistance II (R II) to chloroquine. The duration of fever in the 6 patients with R II to chloroquine was 2-7 days, with the average of 3.3 days. Patients with R II to chloroquine were treated with Fansidar, and all of them were cured.
