Spatial Analysis and Behavior Evaluation to Identify Differentiating Factors of Filariasis Endemic Status

Abstract

Background: The coverage of filariasis Mass Drug Administration (MDA) Indonesia increases from 37.7% in 2011 to 73.9% in 2014. In contrary, reported filariasis case increases from 11,902 cases in 2012 to 14,932 cases in 2014. Pekalongan City has the highest number reported of filariasis cases in Central Java, Indonesia. It has been implementing MDA but it has not decreased the filariasis case number and the Microfilaria rate (Mf-rate) yet. Filariasis elimination in Pekalongan City and many other areas in Indonesia has been prioring MDA, but neglecting environment and behavior factors. Method: This study aimed to identify the factors which distinguish the non-endemic area from the endemic ones in Pekalongan City by spatially analyzing the environmental factors and evaluating behavior. This was an ecological study. The studied-area were 6 high-risk villages, both with Mf-rate >1% (endemic area) and Results: It was identified that all villages had good practice in MDA participation, but only village with Mf-rate Conclusion: Good practice in using mosquito net during sleep and having bush areas organized were the differentiating factors of filariasis endemic status Pekalongan City.
