Weekly variation of rotavirus a concentrations in sewage and oysters in Japan, 2014–2016

Abstract

Concentrations of rotavirus A, in sewage and oysters collected weekly from September 2014 to April 2016 in Japan, were investigated using RT-qPCR; results showed up to 6.5 log10 copies/mL and 4.3 log10 copies/g of digestive tissue (DT) in sewage and oysters, respectively. No correlation was found between rotavirus concentration in sewage and oysters and cases of rotavirus-associated gastroenteritis.
