Table A2.
Descriptive characteristics of the study districts. Number of households and employment status were obtained from the 2012 national census [16]. In household surveys, ~30 households/village were sampled in 6 (range 2–6) villages/district (ranged 93–180 households) per district ([13], Table 2). For school-based surveys, ~100 pupils were sampled per school in 6 (range 3–6) schools/district, whereby questionnaires were administered to 152–645 pupils per district. Dogs counted during surveys, mean dogs per household and vaccination coverage were compiled or calculated from household or school-based surveys. Human/dog ratios (HDRs) were calculated from transects and numbers of vaccinated dogs were compiled from mass dog vaccination campaigns, both conducted in 2014–2015. HHS = household survey. SBS = school-based survey. CI = confidence interval. NA = not applicable.
