Journal Title: IOSR Journal of Dental and Medical Sciences (IOSR-JDMS) - Year 2017, Vol 16, Issue 1
Abstract
Cholera is one of the most important diarrhoeal diseases in India and a major illness of public health importance. Recently there was an outbreak of acute watery diarrhoea in Mathura district, during late OctoberNovember 2016. Objectives: To determine the cause, source and extent of the acute diarrhoeal disease outbreak in district of Mathura by conducting an environmental and microbiological investigation. Materials and Methods: Water samples (1 from pond, 2 from municipal taps, 2 from tube wells and 3 from tanks) were collected from areas reporting the maximum number of cases of acute watery diarrhoea, and tested for diarrhoeagenic pathogens in the laboratory. Isolation and identification of pathogen was done according to the standard methodology. Results: Of the eight water samples tested, four were found to be positive for V. cholerae. The major reason for the outbreak was traced to be contaminated water from one tank, one tap and two tube wells. Conclusion: Our findings demonstrated that water supply of the public water sources, possibly contaminated by the nearby sewerage system, was the probable cause of acute watery diarrhoea outbreak in district of Mathura and the etiological agent was found to be V.cholerae. The people from this area have poor knowledge on proper hygiene. There is urgent need for public awareness against water borne diseases. Also, Mathura being a holy place, is visited by a large number of tourists, who also have access to these public water sources. Continuous surveillance of the outbreak is necessary to contain the spread of transmission.
