Key result
Among 95 water samples from Peshawar, enterovirus was detected in 48.42%, human adenovirus in 38.94%, hepatitis A virus in 12.63%, and rotavirus in 9.47%.
Observational (n=95)
High prevalence of enteric viruses, particularly EV and HAdV, was detected in water samples from Peshawar, Pakistan, correlating with the wet season.
May signal viral risks in Peshawar water supplies; leaves open need for surveillance studies before policy changes.
Viral gastroenteritis and other water-borne diseases are the most neglected areas of research in Pakistan. To determine the quality of water, 4 enteric viruses were studied from different localities of Peshawar, Pakistan. The study validates the viral detection method for Rotavirus (RV), Human adenovirus (HAdV), Enterovirus (EV) and Hepatitis A virus (HAV), directly from water sources of rural areas of Peshawar, KPK, Pakistan. Overall, 95 five water samples were tested; among them, 9.47% were positive for RV, 38.94% for HAdV, 48.42% for EV and 12.63% for HAV. The presence of these viruses in water was directly correlated with meteorological data. High prevalence of EV and HAdV was detected frequently in the wet season from May - September, which can be the potential cause of spreading of gastroenteritis in the population. Environmental surveillance is an additional tool to evaluate the epidemiology of enteric viruses circulating in a given community.

Ahmad et al. (2016) conducted an observational in Water contamination with enteric viruses (n=95). Enteric viruses (RV, HAdV, EV, HAV) was evaluated on Prevalence of rotavirus, human adenovirus, enterovirus, and hepatitis A virus. Among 95 water samples from Peshawar, enterovirus was detected in 48.42%, human adenovirus in 38.94%, hepatitis A virus in 12.63%, and rotavirus in 9.47%.
