We compared cases from the communities and the facilities using unmatched controls (1:2). Cases were patients with acute watery diarrhea, with or without vomiting while controls were persons without history of acute watery diarrhea. We interviewed our study participants using structured questionnaire to collect demographic and cholera risk factors data. We described the outbreak over time, and then tested our hypotheses using unconditional logistic regression at p&amp;lt;0.05.
