Human herpes viruses 6 and 7: history and current state of the problem

https://doi.org/10.24884/1607-4181-2025-32-3-22-30

Abstract

The literature review is devoted to human herpes viruses 6 and 7 (HHV-6, HHV-7). The history of the study of exanthem subitum, the discovery of HHV-7, HHV-6 and its types, epidemiology, pathogenesis, stages of infection, clinical features, laboratory diagnosis and treatment are discussed. Despite some progress in the study of HHV-6 and HHV-7, many aspects of their pathogenesis, their relationship to human pathology, and issues of diagnosis and therapy remain unclear. This is manifested by both under-diagnosis of acute forms of the disease and overdiagnosis of latent infection as acute, which leads to irrational therapy of patients. Further research in this area is needed.
