Epidemiological investigation of cholera outbreak in a periurban slum colony in Chandigarh.
An investigation was carried out in a periurban slum colony in Chandigarh in September 1999 following a report of two microscopically confirmed cases of cholera admitted in Govt. Medical College Hospital, Chandigarh. Rapid survey in the colony covering a population of 1404 found that there were 14 cases of diarrhoea in the colony with attack rate of 9.97/1000 population. Majority (70%) of cases were females and 62% cases were under five years of age. Health education, ORS packets and medications were distributed to cases. Water sampling was also done and it was found that water from one of the hand pump was positive for V. cholerae 01 biotype El Tor serotype Ogawa. Closing of that hand pump and chlorination of drinking water in other parts of slum was recommended to higher health authorities, which was done immediately. Surveillance for diarrhoeal diseases was found to be poor. Provision of safe drinking water, improving sanitation and strengthening of disease surveillance is necessary for control of cholera and other diarrhoeal diseases in slum areas.
