Abstract:

Purpose: Public health officials of the Rabbit District on 18.06.2014 that 28 of them were hospitalized and treated with 684 gastroenteritis patients. The examination was carried out in order to determine the cause of the epidemic, to determine the path of infection and to implement control measures. Method: In this case-control study, between June 07-30, R11, K52, A09 ICD-10 diagnostic code, vomiting or swelling (≥3/day) with a high attack rate in 5 neighborhoods, 154 possible facts and controls selected by a simple random method were studied. The controls, 1:1, were selected from the neighbors by matching the age group. Clinical samples and net water samples have been studied. Results: The outbreak rate is 3.3%, and the cases are spread throughout the district. The main complaints are nausea (%88.9), diarrhea (%88.2), stomach pain (%82. 8) and it is vomiting (%71.8). Cases began to increase 6 days after the flood and a wide pic was detected in the wing of the epidemic. In 66.9 percent of cases, and in 37.0 percent of controls, the neighboring source water (TRRMH=4.3 , 95 percent GA:2.2-8.6), in 18 percent of cases, 27 percent of controls were drunk bottled water (TRRMH=0.5, 95 percent GA:0.3-0,9). In five examples of ejaculation, Norovirus GI and GII were detected. Environmental research has found that there are 35 uncontrolled neighborhood flows in the district, the water warehouse that feeds them is completely filled with flood water. Norovirus was not detected in water samples. The result: the detection of the norovirus in cases, the unprotected neighboring fountain deposits are located right next to the channels that are affected and the findings obtained in the study suggest that the possible cause of the epidemic is the consumption of water from neighboring fountains that are contaminated after severe rainfall.
