The sixth member of the human herpesvirus family, HHV-6, causes early childhood infection with subsequent latency and antibody prevalence of about 60-80%. Active infection is related to a number of acute and chronic diseases such as exanthem subitum, certain cases of infectious mononucleosis and
The paper describes events that in the last fifteen years, have led to the identification of the aetiological agents of three widely known diseases: cat scratch disease, erythema infectiosum and exanthem subitum. The particular features of Afipia felis and Rochalimaea, Parvovirus B 19 and
An HHV-6 antigen capture assay measuring gp116/64/54 antigen was developed. This ELISA is specific for HHV-6 Variants A and B, does not cross react with other human herpesviruses, is sensitive, stable, quantitative, and can detect antigen in body fluids and cell cultures. Relative to virus isolation
Human Herpesvirus-6 is the etiological agent of Roseola infantum and approximately 12% of heterophile antibody negative infectious mononucleosis. HHV-6 is T-lymphotropic, and readily infects and lyses CD4+ cells. The prevalence rate of HHV-6 in the general population is about 80% (as measured by
Six distinct human herpesviruses have been identified. They include Herpes simplex virus type 1 and type 2 (HSV-1 and HSV-2), Cytomegalovirus (CMV), Varicella-zoster virus (VZV), Epstein-Barr virus and the recently described Human herpesvirus 6 (HHV-6). With the exception of HSV-2, the members of
Human herpesvirus 6 (HHV-6) was discovered in 1986. This novel virus is genetically related to cytomegalovirus. HHV-6 mainly infects T lymphocytes but its tropism appears to be much wider and probably involves some epithelial cells. Two HHV-6 variants, designated as A and B, can be distinguished by
