A 3-Month-Old Child with Acute Gastroenteritis with Enterovirus D68 Detected from Stool Specimen.

Enterovirus D68 (EV-D68) is known to be causative agent of mild to severe upper and lower respiratory illnesses in sporadic cases and outbreaks. We present a case report of a 3-month-old child with acute gastroenteritis who visited a pediatric clinic in Kyushu area in Japan in 2015. A stool sample collected from the patient was screened for diarrheal viruses by multiplex RT-PCR. The result showed that the sample was positive only for enterovirus, and EV-D68 clade B3 was identified by sequence analysis of the viral protein 1 gene. This study supports an association between EV-D68 infection and acute gastroenteritis.
