Abstract
Summary
The presence of serum hepatitis (SH), or at least of long incubation period hepatitis, among the hundreds of cases of acute hepatitis which have been occurring annually in U.S. troops stationed in Germany has been established by human volunteer experiments using as the inoculum acute phase plasma obtained from a soldier who had contracted hepatitis in that area. In one experiment, one of 2 sera so tested produced clinical jaundice in 3 of 3 volunteers following incubation periods of 53, 68 and 87 days, respectively. Symptoms suggesting mild hepatitis occurred about 3 weeks after inoculation in 2 of these same 3 volunteers.
