“…If temporary liver damage by acute hepatitis A infection stimulates Kupffer cells and liver macrophages, and this causes antibody rises to childhood viruses, CMV would likely be involved. Although the antibody titers to two other primarily childhood viruses, measles and rubella, were reported to be increased in chronic active hepatitis (Triger, Kurtz, MacCallum, and Wright, 1972) no examination for CMV antibody was made in that study; nor are we aware of acute and convalescent sera from acute hepatitis A cases being examined for antibody changes to such a variety of viral antigens as in the present study.…”
