[The prevalence and etiological structure of viral hepatitis in a climatic-geographic area at high risk for infection].

The spread of viral hepatitides on the territory of Central Asia has been analyzed, taking into account regional and territorial factors and using the Fergana Valley as an example. The analysis, based on the use of modern immunochemical, clinico-epidemiological and biochemical criteria, has made it possible to determine the etiological structure of viral hepatitides on the territory of the Fergana Valley. The epidemic outbreak on this territory has been proved to be caused by viral hepatitis E. The necessity of organizing constant epidemiological monitoring on the interstate and territorial level has been substantiated.
