Spatial Model to Determine Environment-Based Disease: Leptospirosis Vulnerability Zones in Bantul District, Indonesia

Abstract

Leptospirosis is a zoonosis caused by Leptospira bacteria, transmitted through skin wounds or mucous with water or soil contaminated with leptospires from animal urine especially rodents. This paper aims to map spatially the distribution of leptospirosis and to determine a model of leptospirosis-vulnerability areas based on environment variables using the Geographic Information System. The method used was making a zoning map based on the scoring and weighting of the environmental risk variables of leptospirosis transmission. The spatial distribution of leptospirosis in Bantul District in 2019 is evenly distributed in each sub district, the most cases were in Bantul, Sewon, Kasihan sub districts. Leptospirosis vulnerability zones in the center and northern region of Bantul District. Intensive surveillance, treatment and control of leptospirosis as an early warning system in focus areas.
