Mass Blood Survey dan Active Case Detection untuk Pengendalian Malaria diDesa Batunampar, Jerowaru Lombok Timur, NTB

---

Malaria remains a constant problem in coastal area of East Lombok and at a time brings an outbreak.
It raises concern on what would be the underlying factors cause the constant burden of malaria. Among many factors, the great number of asymptomatic cases might plays a role in this problem. The number of asymptomatic malaria tends to get higher among residence of endemic area. The rate of asympto¬matic malaria in East Lombok coastal area is still unknown. Therefore, it is important to conduct mass blood survey to reveal the rate of asymptomatic ma/aria in East Lombok coastal area. Method: Mass blood survey was conducted in Batunampar village, East Lombok. Subjects were residences of Batunampar who agreed to participate in the survey. Malaria parasite was detected using rapid diag' nostic tests and microscopic examination. Artesunate•amodiaquine was given to subjects with positive results. Mass blood survey on February 2007 was subsequently followed with active case detection from 1 March 2007 to 29 February 2008. Results: Subjects of 3038 out of total 5017 villagers were participated in the mass blood survey. RDTs revealed 15 positive subjects consisted of 10 falciparum positives, 4 vivax positives, and 1 faJciparum•vivax mix positive. From 15 positive subjects only 4 subjects (27%) had fever, the remaining 11 subjects were asymptomatic. All positives subjects were treated with artesunate•amodiaquine. Two subjects were al/ergic to ertesunste-emodiequine. Active case detection in one year period found 296 fever with no malaria positive. Discussion: Mass blood survey was unable to cover 100% population of Batunampar due to high mobility of villagers and the scarcely distributed houses in the large area of the vii/age. The high percentage of asymtomatic sub¬jects depsite of high parasitemia (73%) can be caused by immune status, type of infectuive palsmodi• um and parasite density. The high asymtomatic insidence of malaria is also recovered in other countries where active blood mass survey are done. Based on the ACD, AMI in batunampar village in 2007 was 59% with API 0%. Conclusion: First, The high rate of asymptomatic malaria found in the positive sub¬jects should bring the issue of asymptomatic malaria in health care planning of health provider in East Lombok. A greater yield study to reveal asymptomatic malaria should be carried out to correctly iden¬tify the rate of asymptomatic malaria. Second, since there was a significant discordance between AMI and API, blood film examination should be done to all suspected malarial patients. Thir, Api shouldbe considered as the best malarial control program
