Key result
Enterovirus detection in ~30% of brackish water samples correlates with enterococci and low temperatures.
Why the study?
Enteroviruses are a waterborne nonbacterial cause of gastroenteritis and have recently emerged as a concern to health authorities.
Observational (n=46)
Enteroviruses, including several human and porcine serogroups, are detectable in brackish water from the Damshui River and correlate with enterococci and low temperatures.

Enterovirus detection in brackish river water signals potential transmission risk; leaves open serogroup data and clinical impact assessment.
Enteroviruses have recently emerged as a concern to health authorities because they are a waterborne nonbacterial cause of gastroenteritis. Forty-six samples of brackish water from two sites upon the Damshui River, Taiwan, were analyzed for the occurrence and serogroups of enteroviruses. The seminested reverse transcriptase polymerase chain reaction was used for detecting enteroviruses. Six of the 23 water samples from one site and eight from the other site tested positive for enteroviruses. Detection results were identified by the nucleic acid sequencing method. Five serogroups of enteroviruses were identified as coxsackievirus A2, coxsackievirus A6, echovirus 11, enterovirus 71, and porcine enterovirus 9. The occurrence of enteroviruses within the water samples shows significant correlations with the occurrence of enterococci and low water temperatures.

Chen et al. (2008) conducted an observational in Enterovirus contamination (n=46). Environmental conditions (enterococci and low water temperatures) was evaluated on Occurrence and serogroups of enteroviruses. Enteroviruses were detected in 14 of 46 brackish water samples from the Damshui River, with occurrence significantly correlated with enterococci presence and low water temperatures.
