The influence of several factors on the course of herpes zoster was studied in 151 patients. Dissemination of zoster was associated with the presence of a concurrent disease, especially Hodgkin's disease, and/or the use of immunosuppressive therapy. Several host-immune parameters, including quantitative immunoglobulins, circulating lymphocyte counts, delayed hypersensitivity to multiple skin test antigens, and lymphocyte transformation to phytohemagglutinin did not correlate with dissemination of disease. Development of virus-specific complement-fixing antibody (CFA) was delayed in some patients with disseminated disease.
