The epidemic process of viral hepatitides, presented with chronic forms in dynamics, has undergone significant alterations, consisting in the change of the leading age groups in the formation of disease morbidity. In the first and second periods of observation (1962-1994) in the epidemic process mainly adults and children were involved. Under the influence of socio-economic conditions and changes in the moral and ethical foundations of society in the third period in the formation of chronic liver pathology the equity participation of adolescents, young adults increased, and the proportion of children and older groups of adults decreased. Increasing the percentage offemales in the structure of incidence of chronic viral hepatitis is an unfavorable sign. Gender and age-related changes in disease morbidity contributed to the decline in mortality from chronic viral hepatitides.
