The results of the study of the registered morbidity caused by herpes viruses (HHV) type 4, 5, 6 in preschool children in a large industrial region are presented. Materials and methods. The information on the registered incidence of acute forms of HHV-4, 5, 6 infections in hospitals and clinics in Perm and Perm Krai in 2015—2018 was studied.
