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. Mapping cases of dengue infection and resistance tests organophosphates contribute to the spread of dengue infection.

Method : Data were collected by observation, put ovitrap inside and outside the house of cases  in November until February 2012 and then resistance test of mosquito larvae, mapping using a global positioning system (GPS).  Analysis using spatial analysis and absorbent value (AV).

Result : Tendency cases to cluster at 3000 m from health centers and further away from the health center more and more cases. Cases in crowded housing has a high tendency.  Mosquito Aedes aegypti in South Denpasar District of resistance to organophosphates.

Conclusion : The areas classified as resistant is Pemogan village, Sanur, Renon, Panjer and Sesetan, while the Village Sidakarya classified as sensitive. Clumped distribution pattern forming clusters of cases within 3 miles of the public health centre.
