Figure 1 — Key Takeaways: Households with no handwashing facility had the highest diarrhea prevalence (17 cases, 3.0%), compared to water-only (6 cases, 2.8%). Zero diarrhea cases were observed in soap & water households — the strongest protective WASH behavior. Handwashing with soap appears to be a key modifiable risk factor for waterborne illness.
Figure 2 — Key Takeaways: The sample was predominantly female (n=856, 87.6%), reflecting the household survey design. Diarrhea proportions were similar across sexes: 2.5% (female) vs. 1.7% (male) — sex alone is not a strong predictor of diarrhea risk. The log scale is especially useful given the large group size imbalance (856 vs. 121).
Figure 3 — Key Takeaways: Diarrhea cases were concentrated in the illiterate (n=19, 2.5%) and some primary (n=3, 5.0%) groups. Zero cases in high school/preparatory and college/university groups suggest a strong protective educational gradient. Education may be an important effect modifier of the WASH–diarrhea relationship.
Figure 4 — Key Takeaways: Median age was 30 years (IQR: 25–39.5) in diarrhea cases vs. 35 years (IQR: 28–40) in non-cases. The overlapping IQRs suggest age alone is not a strong predictor of diarrhea risk. Hover over each box to explore the full 5-number summary.
Why this matters: Diarrheal disease remains a leading cause of child morbidity in rural Ethiopia. Identifying modifiable WASH risk factors — particularly handwashing with soap — provides actionable targets for community health interventions and policy. | 📎 Source Code on GitHub
Data Source: Household survey dataset from Hararghe, Ethiopia (confidential — not publicly available).
Sample Size: 977 households.
Data Collection: Data were collected via structured household interviews using a cross-sectional survey design targeting household-level WASH practices and health outcomes in the Hararghe region of Ethiopia.
Study Population: Household respondents (87.6% female) aged 8–78 years residing in Hararghe, Ethiopia; 76.5% of respondents were illiterate.
Outcome: Diarrhea cases reported in the past month (Yes: 23 households, 2.4%; No: 954 households, 97.6%).
Key Exposures: Handwashing practice (no facility / water only / soap & water), sex, age, and educational status.
Why this matters: Diarrheal disease remains a leading cause of child morbidity in rural Ethiopia. Identifying modifiable WASH risk factors — particularly handwashing with soap — provides actionable targets for community health interventions and policy makers working to reduce waterborne illness burden in the region.
