Some Modern Epidemiological Aspects of Hemocontact Viral Hepatitis B And C Using the Example of a Large Region

Hemocontact viral hepatitis can remain undetected for a long time due to the prolonged incubation period (up to 180 days) and the absence (or mild nature) of symptoms. When seeking medical care, such patients become sources of nosocomial infections. The aim of the study is to assess some epidemiological aspects of the incidence of hemocontact hepatitis B and C in a large region. Materials and methods included data from reporting form No. 2 of the Federal State Statistical Observation «Information on Infectious and Parasitic Diseases» in the Altai Territory for the period 2000-2023. The results of the study revealed that in the Altai Territoryi, the proportion of hepatitis C in the structure of viral hepatitis incidence has increased. Over the past two years, there has been a trend toward an increase in the incidence of chronic hepatitis B and C. The adult population contributes the most to the age structure of hemocontact viral hepatitis incidence.
