During July 2009 an outbreak in neonates represented with gastrointestinal and respiratory symptoms was observed at the Neonatal Postintensive Care Unit, Clinical Hospital Center, Zagreb. Human parechovirus type 1 (HPeV1) was isolated from seven patients, one of whom was asymptomatic. All but one were premature neonates with serious underlying conditions, and all recovered fully after several days.
