Use of gamma globulin for control of infectious hepatitis in an institution for the mentally retarded.

EARLY in 1954 there were 2 cases of jaundice in a state institution for the mentally retarded in Maine. During the ensuing six months 157 cases of frank jaundice and a large but unknown number of cases of digestive upset with abdominal pain without jaundice occurred. When it was realized that this was an epidemic of infectious hepatitis gamma globulin was used apparently with dramatic results. The institution has a capacity of 1507, and admits persons from five to forty-five years of age. There are 5 buildings housing females and 4 buildings, as well as 2 farms, that house males. . . .
