| description | Background and Objectives: In June 2018 , 537 residents of a rural area in Khuzestan Province presented to the regional Comprehensive Health Service Center for gastroenteritis symptoms. This study was designed to determine the extent and cause of the outbreak.
Methods: A case-control study was performed after random selection of the case and control groups (80 cases and 88 controls). Clinical and water samples were analyzed for parasitic, bacterial and viral pathogens in local, provincial and national laboratories. Odds ratios with corresponding 95% confidence intervals were used to assess the relationship between disease and exposure.
Results: The odds ratio of rural plumbing water consumption as a risk factor was 3.3 (95% CI: 1.7-6.2). Using in vitro methods, Shigella sonnei was isolated in clinical samples and enterohemorrhagic Escherichia coli and enteropathogenic Escherichia coli were isolated from both clinical samples and water samples taken from the intake basin of water supply facilities.
Conclusion: Consumption of rural plumbing water Since 26 June 2018 as well as the water stored in domestic tanks at certain water-shut-off times is associated with gastroenteritis outbreak. To prevent similar outbreaks, continuous chlorination of drinking water during distribution through rural pipelines should be done. To prevent secondary outbreaks after the epidemic phase, educating and informing people about personal hygiene is essential. |
