Currently there are about 200 different studied herpes viruses, only 8 types are pathogenic for humans. They all belong to the family Herpesviridae, which according to the structure of the virion and biological properties is divided into three subfamilies: α, β, and γ. Human herpesvirus 6B belongs to the subfamily of β-herpesvirus, genus Roseolovirus. The overview of current information on the etiology, epidemiology, clinical manifestations of infection caused by human herpesvirus 6B is presented. The diagnosis of the viral exanthema using modern laboratory technology is considered.

Human Parvovirus B19 has been recognized as the causative agent of a wide range of diseases. The cellular receptorfor parvovirus B19 is P antigen located on the trophoblast cells, bone marrow, liver, kidney, synovium, etc. has been associated with many clinical situations, erythema infectiosum and erythroblastopenia crisis. In the absence of P-antigen, revealed no susceptibility to parvovirus infection. Infection in pregnant women under 20 weeks gestation can lead to miscarriage or non-immune hydrops, fetal death. 1-5% of women are susceptible to parvovirus infection during pregnancy. Viral infection may be responsible for aplastic anaemia in immuno-compromised patients. Diagnosis ofparvovirus infection B19 is based on the results of general blood analysis; biochemical analysis of blood; serological methods, PCR detection of IgM, immunoblot IgM/IgG. The most common clinicalform of parvovirus B19 infection in children is erythema infectiosum. It is also called “fifth disease”. Erythema infectiosum is characterized by a viral prodrome followed by the “slapped cheek’ facial rash and macula papular lace or mesh rash on the skin of the trunk and extensor surfaces.

Palmar-plantar keratoderma is a heterogeneous group of hereditary dermatosis, which can be independent diseases or combined with various congenital malformations, most of ectodermal origin. Approaches to differential diagnosis and clinical features of each form of this pathology are described. Keratoderma, Unna Toast genodermatosis belongs to the group, which is characterized by hyperkeratosis on the palms and soles without migration to other skin areas.
