This article presents the results of a study of the epidemiology of hepatitis E in the Russian Federation. Obtained data explaining the phenomenon, known as the Balayan paradox — the wide distribution of anamnestic antibodies to the hepatitis E virus in the absence of a registered incidence. It was shown that imported cases of infection are not able to support the epidemiological process of hepatitis E in Russia. The most cases of HEV infection are autochthonous in nature and are associated with zoonotic transmission of genotype 3 virus from pigs.
