Correlation of Container Characteristic, Water-Container Draining Practice, and the Ownership Status of Residence with the Presence of Aedes Sp Larvae in Tembalang, Semarang

Abstract

Previous studies mostly defined Tembalang as an endemic area of dengue fever with highest incidence rate (IR) in District of Semarang. The incidence of dengue fever in Tembalang in 2016 is still high, which is 113.9 per 100.000 citizens. A number of free larvae in Tembalang is still below the target (86.26%). The presence of Aedes sp larvae is influenced by human and environmental factors. The aim of the study was to identify the relation between container characteristic, practices of mosquito habitat diminishing, and the ownership status of residence with the presence of Aedes sp larvae in Tembalang. This research was an analytic observational research with stratified random sampling. Data collection methods were observation and interview, conducted from August-October 2017. The result of this study showed that House Index (HI) was 25%, Container Index (CI) was 11.2%, Breteu Index (BI) was 26% and number of free larvae was 75%. Chi-square analysis showed number of container was related to the presence of Aedes sp larvae (p 0.000). The society needs to make efforts to improve the number of free larvae by doing practices of mosquito's habitat diminishing especially if they own more than 3 containers.
