“…As for the causes of viral gastroenteritis, noroviruses and rotaviruses are the most common pathogens (Leclerc et al 2002;Jain & Jain 2014). Multi-pathogen gastroenteritis outbreaks are common in Turkey caused by drinking contaminated water, and prevalent pathogens, such as E. coli and norovirus, may lead to waterborne outbreaks in Turkey (Sezen et al 2015;Sahan et al 2017;Özgüler et al 2019). For low-and middle-income regions, water supply systems of rural areas are assessed to have shown higher contaminations with enteric pathogens compared to urban areas.…”

Disruption of routine monitorization and chlorination of the water supply system during a week-long holiday led to a multi-organism gastroenteritis outbreak in a district with limited laboratory support. More than a 10-fold increase in patients with gastroenteritis was reported. Enteropathogenic Escherichia coli, Enteroaggregative E. coli, and norovirus were detected in human specimen samples. The main water tank and pipes were rusted; 13 out of the 19 water samples tested positive for total Coliform (1–920 colony-forming units (CFU)/100 ml) and E. coli (1–720 CFU/100 ml). Chlorine levels were below 0.2 ppm in seven of the nine samples. Information of 1,815 cases was obtained from the hospital records with a crude attack rate of 2.9%. Cases widespread in the district increased throughout the holiday, epidemic curve revealed a point-source outbreak. The case–control study revealed that consumption of drinking tap water and using it to clean vegetables/fruits were significantly associated with the illness. While drinking only bottled water had a protective effect against the illness. The culture technique showed that the water supply samples were positive for pathogenic bacteria. Upon decision in a multi-stakeholder meeting, the water tank was cleaned, and the Municipality initiated the renovation of the water supply system.
