One third of the respondents did not have good practice for prevention of cholera. Lack of adequate supply of water and gas to boil water, unconsciousness, high density of population and living places surrounded by drainage water were identified as reasons for not having good practice.This study shows significant association between respondents' knowledge and sex, education, occupation, monthly household expenditure, attitude and practice (p<0.05). In the adjusted model, female were 74% less likely to have poor knowledge than male (Odds Ratio (OR): 0.74; 95% CI: 0.62-0.87). Compared to respondent's high monthly household expenditure (>128US$), the significant odds (OR: 1.31; 95% CI: 1.09-1.58) was found with the respondents who had monthly lowest household expenditure (< = 93US$) that they were more likely to have poor knowledge.Conclusion: This study recommended to strengthen health education activities to improve knowledge of low socio-economic group of people on cholera and cholera vaccine and emphasized the importance of mass cholera vaccination to prevent and control cholera.
