Abstract

Brebes Regency is an endemic area of Lymphatic Filariasis (LF) and has the highest number of LF case in Central Java Province, Indonesia. Despite it is located in coastal region, which is already known as one of risk factors of LF, the LF case is distributed more in rural area, away from the shoreline. Adult mosquito need a certain site, called resting place, to rest after and before bitting for blood meal. The purpose of this study was to analyze spatially the distribution of LF case and mosquito resting place in three subdistricts whose highest LF case in Brebes Regency. The three subdistricts are rural areas. The observed resting places were cattle pen, unmaintained bushes, and maintained bushes. The data of LF patients were obtained from Health Office of Brebes Regency which stood at 14 patients. Spatial mapping of LF case and mosquito resting place distribution was composed. 4 patients were located in mosquito flight radius from unmaintained bushes, 3 patients were located in mosquito flight radius from cattle pen, and 7 patients were located in mosquito flight radius from both unmaintaned bushes and cattle pen. It indicated unmaintained bushes togather with cattle pen is the main resting place which contributed to LF transmission.
