BACKGROUND - Although rotavirus and norovirus cause nearly 40% of severe endemic acute gastroenteritis (AGE) in children <5 years of age in the United States, there are limited data on the etiologic role of other enteric viruses in this age group.

METHODS - We conducted active population-based surveillance in children presenting with AGE to hospitals, emergency departments, and primary care clinics in 3 US counties. Stool specimens from these children and from age-matched healthy controls collected between October 2008 and September 2009 were tested for enteric adenovirus, astrovirus, sapovirus, parechovirus, bocavirus, and aichivirus. Typing was performed by sequencing and phylogenetic analysis.

RESULTS - Adenovirus, astrovirus, sapovirus, parechovirus, bocavirus, and aichivirus were detected in the stool specimens of 11.8%, 4.9%, 5.4%, 4.8%, 1.4%, and 0.2% of patients with AGE and 1.8%, 3.0%, 4.2%, 4.4%, 2.4%, and 0% of healthy controls, respectively. Adenovirus (type 41), astrovirus (types 1, 2, 3, 4, and 8), sapovirus (genogroups I and II), parechovirus (types 1, 3, 4, and 5), and bocavirus (types 1, 2, and 3) were found cocirculating.

CONCLUSIONS - Adenovirus, astrovirus, and sapovirus infections were detected in 22.1% of the specimens from children <5 years of age who had medical visits for AGE and tested negative for rotavirus and norovirus. No causal role for parechovirus and bocavirus was found.
