In the 197576 school year, 3 cases of icteric hepatitis occurred almost simultaneously in 2 grades of an Athenian school. An initial survey of the 2 classes approximately one week later found that 88 of 94 children were susceptible to type A hepatitis. No further clinical cases occurred. A second survey at the end of the school year revealed only 2 subclinical hepatitis A virus infections: one coincident with the over cases in November, and a second from extramural exposure in February. Two carriers of hepatitis B virus in class A were not associated with serologic evidence for communicability of that agent in this setting. Testing of faecal specimens for agents possibly responsible for epidemiological interference with the spread of hepatitis A virus was unsuccessful. Nevertheless, the hypothesis of Bang that other agents may interfere with transmission of hepatitis A virus deserves further study.
