title: [Polyvirus hepatitides (prevalence, diagnosis, characteristics of virusological process)].
abstract: OBJECTIVE
  To ascertain prevalence of chronic hepatitides (CH) of polyvirus etiology and to characterize a course of such polyvirus CH.
  
  
  METHODS
  A total of 15000 patients with chronic diseases of the liver (CDL) of different etiology were examined for markers of hepatotropic viruses, 312 patients with CH aged 18-59 years were examined clinically, biochemically, virusologically and morphologically.
  
  
  RESULTS
  CH of polyvirus etiology are rather prevalent. A replicative form of HBV has a significant effect on the activity of the pathological process in mixed hepatitis. Incidence of chronic HBV and HCV infection rises with age. Viral hepatitis A in drug addicts runs an atypical course.
  
  
  CONCLUSIONS
  Adequate epidemiological analysis, diagnosis and antiviral treatment, follow-up of CDL of mixed viral etiology, monitoring of drug addiction, healthy life style are able to reduce prevalence of mixed hepatitis.
