Stool samples and water samples were taken for laboratory investigations. Various interventions including contact tracing and community sensitization were employed to contain the outbreak. A descriptive analysis of the data and review of literature was used to determine the quality of detection, investigation and response to this cholera outbreak. Results revealed that sixty six people were clinically affected 8 of who were laboratory confirmed for strain 01 Ogawa. The case fatality rate (CFR) was 4.5%(3/66). The outbreak was detected and contained within 24 days.The CFR was high compared to the WHO standards of a similar scenario in the 2012 outbreak in the same area. Of the 3 deaths, one was brought in dead and a week into the outbreak while the other two died at the health facility. The two fell sick in Congo DR and brought to Kapisha health post for treatment. Although the high CFR indicates inadequate response or poor case management the general response and management of the cases seemed adequate with detection and response within 48 hours of the notification. The interventions employed played a pivotal role in containing the outbreak.Based on the CFR, it was concluded that the response to the outbreak was inadequate. However, the outbreak was generally well managed. The interventions implored as a response to the outbreak and active and rapid response contributed to the containment of the cholera in Nsama district within a short period.
