An outbreak of hepatitis A occurred among the members of the Japan Overseas Corporation Volunteers (JOCV) stationed in the Philippines. Seven out of 10 youths who ate, but none of five youths who did not eat raw oysters developed hepatitis. All these seven cases were positive for hepatitis A antibody (anti-HAV) and six of them were also positive for anti-HAV IgM (immunoglobulin M) 111 days after the infection.
