Infectious hepatitis Dr. J. D. Purvis, Pennsylvania Department of Health, has reported the occurrence of several outbreaks of infectious hepatitis. In one small community, the disease is considered to have been spread through contacts in school buses. It is estimated that 40 cases have occurred in this instance. In another area of the State, an outbreak began about the middle of October and cases are still occurring. Cases have been concentrated in one town, but scattered cases in the county and surrounding counties have also been reported. A total of 125 cases has been reported up to the present time. In a third community, 100 cases and 100 suspect cases were noted from April through November. With the opening of school, cases began to increase but gamma globulin inoculations brought the outbreak under control. The fourth outbreak, consisting of 156 cases throughout 1953, occurred in another area. Gamma globulin has been used in all the above cases as a means of prevention. Table 1.
