In societies showing moderate endemicity, primary transmission route is personal contact, on the other hand water originated outbreaks may be seen.

Methods and Results : In this study, a hepatitis A outbreak observed in a local school following an explosion in the sewer system in a street in Istanbul Sar›yer on September 27th 2004, is investigated. 32 children attending this school and living at homes around had hepatitis A clinically; the first case seen 25 days after the explosion. Age distribution of the children is 1-18 and the mean age is 8.4. The first case was detected on October 22nd and 21 cases were reported in the first 6 days and 32 cases were seen in 17 days.
