Spatial distribution of subjects with <i>Leptospira</i> antibodies and all enrolled subjects, according to place of residence, and environmental attributes of the community site.

<p><i>Panels A</i> and <i>B</i> show the smoothed Kernel density distribution of subjects with <i>Leptospira</i> antibodies (N = 489) and all (N = 3,171) subjects, respectively, according to place of residence. The yellow-to-red gradient represents increasing density in smoothing analyses which used 40 meters as the bandwidth. Black circles show the location of subject households. <i>Panel C</i> shows the distribution of the population-adjusted Kernel density estimator for subjects with <i>Leptospira</i> antibodies which was calculated as the ratio of the estimators for subjects with <i>Leptospira</i> antibodies and all subjects. <i>Panel D</i> shows a topographic map generated by the digital terrain model. The yellow line is the level that is 20 meters above the lowest point in the four valleys within the community site. <i>Panels E</i> and <i>F</i> show the distribution of, respectively, open rainwater and sewage drainage systems and accumulated refuse according to size (m<sup>2</sup>).</p>
