Journal Title: Journal of Communicable Diseases - Year 2017, Vol 49, Issue 1
Abstract
Background: On 4th October 2012, a death due to ADD was reported at Civil Hospital Batala, Punjab followed by a sudden rise in the number of cases. We sought to establish the cause and source of infection. Methods: A case was defined as a person who had three or more loose stools with or without vomiting per day between 4th October to 8th November 2012 from Gandhi Nagar Camp and adjoining colonies. To ascertain cases, a house to house survey was conducted in the affected area. Water specimens from households were tested for potability and stool culture was performed to identify the causative agent. Results: A total of 834 cases and 33 deaths were identified from a population of 24,765 {attack rate (AR): 3.4%, case fatality ratio (CFR): 4%}.The AR was significantly higher among females (n=440) compared to males (n=394; p<0.002) and among those older than 54 years (n=105; p<0.001). CFR was higher in males (6.1%) and in those >54 years old among both sexes. The most affected area was Gandhi-Nagar (AR- 6.6%). Vibrio cholerae O1 Ogawa was identified in 8/35 stool samples. 12/23 water samples demonstrated fecal contamination. Conclusions: Identification of broken drinking water supply pipeline which resulted in fecal contamination prompted public health action to repair the water pipe and helped in controlling further occurrence of cases.
