title: Fever of undetermined origin: role of cytomegalovirus and Epstein-Barr virus.
abstract: Roles of various infections, neoplasms and granulomatous diseases in fever of unknown origin were studied in 22 patients. Bacterial infections were responsible in seven (32 percent), herpes viruses in five (23 percent), neoplasms in four (18 percent) and granulomata in two (9 percent) cases. Patients with herpes infections had initially no clinical or routine laboratory clues to viral involvement, and were given an intensive workup for 5 to 15 days. The diagnosis was made on the basis of cytomegalovirus or Epstein-Barr virus lgM antibody titers.
