Spatial Mapping Dengue Infection and Vulnerability Test on Aedes Aegypti to Organofosfat in South Denpasar District, Denpasar, Bali

Abstract

Background : Dengue hemorrhagic fever (DHF) is a global health problem. Denpasar City is one of the endemic areas in Bali Provincei. South of Denpasar sub-district is one of the area with the highest dengue cases in the other districts. Prolonged use organophosphates cause resistance in mosquitoes.
