Parvovirus B19 infection: characteristics of population immunity in the world

Parvovirus B19 infection (PVI) is one of the relatively new problems in infectology, data on the study of its prevalence in our country began to appear only at the beginning of the twenty-first century. The article presents the results of an analysis of studies from available literature sources highlighting the prevalence of PVI markers at the population level among different social groups of the population at the present stage. The clinical manifestations of PVI are diverse, which requires differential diagnosis, both with exanthemic infectious diseases and with non-infectious pathology. Due to the peculiarity of PVI pathogenesis, it is relevant for various socially significant populations, primarily patients with exanthemic manifestations of various diseases, persons from among blood donors, pregnant women and women planning pregnancy. Furthermore, unlike most countries, our country does not have a system for PVI detecting and reporting in the system of state sanitary and epidemiological supervision, which makes it difficult to conduct research on this topic.
