A total of 240 units (20.8 %) consented and responded to the survey invitation. About 77 % of the expected knowledge and attitude were observed in at least 80 % of the participants, compared to only about 31 % of the expected behaviours and practises. Being single [adjusted odds ratio (AOR) = 2.29; 95 % CI = 1.16-4.48], having flu in the past six month (AOR = 3.24; 95 % CI = 1.74-6.06), preferred self-medication (AOR = 2.07; 95 % CI = 1.06–4.12) were risk factors of diarrhoea. Washing hands with water before attending to children or sick persons (AOR = 0.30; 95 % CI = 0.11–0.82), washing hands with water (AOR = 0.16; 95 % CI = 0.05–0.45) and water with soap (AOR = 0.29; 95 % CI = 0.12–0.72) after attending to children or sick persons, and hand washing between 30 s to a minute (AOR = 0.44; 95 % CI = 0.20-0.90) were protective factors against diarrhoea.
