Household spraying in cholera outbreaks: Insights from three exploratory, mixed-methods field effectiveness evaluations
Household spraying is a commonly implemented, yet an under-researched, cholera response intervention where a response team sprays surfaces in cholera patients’ houses with chlorine. We conducted mixed-methods evaluations of three household spraying pro- grams in the Democratic Republic of Congo and Haiti, including 18 key informant interviews, 14 household surveys and observations, and 418 surface samples collected before spray- ing, 30 minutes and 24 hours after spraying.
