Entomological Index and Vector Distribution of Dengue Hemorrhagic Fever (DHF) Based on Container Characteristics in Kelurahan Cipageran Cimahi

Abstract

Dengue hemorrhagic fever is an infectious disease infected through the bites of Aedes sp.mosquito. The pattern of DHF incidence fluctuates every year, which is influenced by environmental factors which cover the breeding place of Aedes aegypti Mosquito. One measure taken in controlling the Aedes aegypti mosquito is to locate where the breeding place is. The aim of this study was to determine the potential for breeding place of Aedes aegypti mosquito, the results of this study was the entomology index in Kelurahan Cipageran Cimahi. The study was conducted in 2019 inputted using the REDcap Application with a descriptive method as sampling survey, the number of samples taken was 100 houses. The entomology index of Container Index (CI) was 58,6%, House Index (HI) was 60% and Breteau Index(BI) was 153%, while larva free number was 40%. The average dengue vector larvae density based on CI, HI and BI in Kelurahan Cipageran RW 08 scale was 5-8, which fell under the medium risk category. The results showed that the containers with positive larvae of Aedes sp. were found at 60% which spread almost evenly. Microscopic examination showed that the larvae found were Aedes sp larvae, it was concluded that Aedes sp larvae mostly found in the bathtub and plastic bucket inside the house. The larvae free number recorded in Cipageran Village RW 08 Cimahi was still relatively low, it might occur due to environmental factors like breeding places of Aedes sp. mosquito and the habits of the people who collected water without container cover so that it had the potential to become a breeding place for Aedes aegypti mosquitoes.
