Modern data on the biology of Human Herpesvirus 6 and pathogenesis of Human Herpesvirus 6-associated clinical conditions (review of scientific publications)

Despite almost universal detection of human herpesvirus 6 in general population (up to 90% of individuals are considered seropositive), human herpesvirus 6-associated diseases remain poorly explored. Knowledge of this microorganism has greatly increased over the recent 10 years. The review presents modern data on the biological properties of the human herpesvirus 6, highlights the epidemiology, variety of clinical forms and variants of the course of the disease, pathogenesis of the infection. Specific features of the human herpesvirus 6 were described. They determine difficulties of laboratory diagnostics of the infection and create problems in choosing treatment tactics.
