Estimated association between mean cholera attack rate (AR) from 2016 to 2020 and water, sanitation, and hygiene (WaSH) status in study kebeles in Shashemene Town and Shashemene Woreda. The association is shown for three components of WaSH with “at least basic” status: drinking water source, sanitation, and hygiene. Each line represents LOESS (locally estimated scatterplot smoothing) estimates of association between mean cholera AR and status of respective WaSH components, with nonparametric 95% confidence intervals (gray shaded areas). Each dot represents the surveyed kebele. The x-axis represents the proportion of households with “at least basic” WaSH status by kebele, and the y-axis, mean cholera AR.
