Study enrolment was performed by passive recruitment at village community centres. Villages were clustered, post-hoc, into twelve clusters by spatial proximity (additional detailed map data found in Additional file 1: Fig. S1). The median number of individuals per cluster was 89 (IQR 80–133) and the median number of individuals per village was 36 (IQR 13–64)
