Abstract Background: Cholera continues to be a major public health problem in developing countries, often presenting in epidemic forms due to poor water sanitation and hygiene practices. A sudden surge of acute diarrhoeal cases was reported in Millat nagar Urban area of Nanded city in Maharashtra, necessitating an urgent epidemiological investigation.
Objectives: To provide a comprehensive overview of a urban cholera outbreak, identify the source of infection, strengthen surveillance, and recommend timely public health responses for outbreak containment.
Materials and Methods: A descriptive epidemiological investigation was conducted following an outbreak reported late night on 24 November 2025 in Millat nagar urban area (population 3271). An 8-member multidisciplinary team conducted house-to-house surveys, sanitary inspections, and spot mapping. Clinical assessment, line listing, and stool and water sample collections were performed to confirm the aetiology.
Results: A total of 16 cases were identified, yielding an overall attack rate was 4.8 per 1000 population with a 0% case fatality rate. Among the 02 cases admitted to the Government Medical College (GMC) and at UHC, the 0–10 years age group constituted the largest single category (11/16). Overall, males accounted for 43.75 % of the cases. The outbreak peaked on 25 November 2025 and was linked to contaminated pipe water valves surrounded by stagnant drainage pits. Stool samples from GMC admissions demonstrated darting motility suggestive of Vibrio cholerae O1 biotype El Tor. While 13 water samples were deemed unsatisfactory for drinking, effective clinical management and mitigation measures prevented mortality.
Conclusion: The outbreak was driven by contaminated water infrastructure and poor environmental hygiene. Prompt surveillance, timely rehydration, and coordinated public health interventions effectively contained the outbreak.
