Endemic coastal malaria in the Thousand Islands District, near Jakarta, Indonesia.

Objectives: To conduct malaria surveillance near Jakarta where only imported malaria has been described over the past two decades and to characterize endemicity and risk to heavily populated peri-urban locations.

Methods: Standard cross-sectional malariometric surveys and mosquito collections at the Thousand Islands District and developing peri-urban areas of Jakarta.

Results: During October 2000 outbreak investigations in the Tidung Island group, the slide positive rate was 47% (38%Plasmodium falciparum, 7%P.

Short report: therapeutic efficacy of chloroquine combined with primaquine against Plasmodium falciparum in northeastern Papua, Indonesia.

Chloroquine combined with primaquine was evaluated for therapy of uncomplicated malaria caused by Plasmodium falciparum in nonimmune Javanese migrants to northeastern Papua, Indonesia. Subjects were randomized to treatment with standard chloroquine therapy (25 mg/kg in 3 doses over the course of 48 hours) with 30 mg primaquine administered daily for 28 days (n = 25) or a placebo of primaquine (n = 28). The 14-day cumulative incidence of therapeutic failure was 56% with primaquine and 79% with placebo (odds ratio [OR], 0.
