Abstract

The 39 oyster consumption-related cases of hepatitis A reported in 2005 represent the first large outbreak of hepatitis A associated with shellfish consumption in the United States in >15 years. This is the first outbreak investigation in which an identical hepatitis A virus sequence was obtained from both the implicated food product and case patients.
