[The epidemiological diagnosis of "fecal-oral" hepatitis E in Tajikistan].

On the basis of the results of the retrospective epidemiological analysis of hepatitis A morbidity for many years in the Leninabad (now Hojend) region of Tajikistan the possibility of the epidemiological diagnosis of fecal-oral hepatitis non A, non B, also known as hepatitis E, was confirmed.
