Biennial pattern of rotavirus gastroenteritis in the Netherlands and a shifting age distribution following a low rotavirus season, 2010-2016.

A hyperendemic rotavirus season was expected after a low-endemic 2014 season in the Netherlands. Rotavirus detections were however similar in 2015 and lower in 2016 compared with 2010-2013. Gastroenteritis consultations rates were also similar in 2015, but the age-distribution shifted to older children due to an accumulation of non-infected children. Results indicate a possible shift to a biennial rotavirus pattern. (aut. ref.)
