According to results of follow-up observation, after acute viral hepatitis with cyclic course the majority of recurvalescents recover. Chronic persistent hepatitis was registered only in 44 (2%) out of 2187 patients. Among patients with hepatitis with a prolonged course, complete recovery was noted only in 16.7% of patients.</p>Kazan Medical archiveКазанский медицинский архив
