Remote Sensing and Geographic Information Systems as Decision Support Tools for Malaria Control in the Republic of Korea
Abstract
Cost-comparisons are a necessary component of decision-making in the control of vector-borne disease. Remote sensing and geographical information systems (GIS) were used to estimate the size of vector larval habitats to allow a cost comparison of chemoprophylaxis and larviciding, two malaria control methods currently being considered for use in the Republic of Korea (ROK). Two U.S. Army camps (Cp Casey and Cp Greaves) were selected as research sites. The cost of chemoprophylaxis was estimated for each population assuming a 19-week treatment regimen consisting weekly chloroquine chemoprophylaxis with terminal primaquine treatment, a single pre-treatment G-6-PD deficiency test, and a 50% turnover in personnel during the malaria transmission season. Annual cost of chemoprophylaxis was $37.53/person. Larval habitats were sampled from June through September, 2000. Anopheline larvae were reared to the adult stage and identified using adult and pupal morphological characteristics. Gene sequencing and random amplification of polymorphic DNA (RAPD) analyses were performed to confirm the identification of the mosquitoes. Both molecular work and pupal morphology indicated that most of the anophelines collected during the study were Anopheles sinensis Wiedemann and that the abundance of other anopheline species is generally overestimated by adult keys.
