[The prevalence of etiological forms of viral hepatitis in Khabarovsk].

For the first time the etiological structure of viral hepatitis in the Far East, in Khabarovsk, has been studied. The leading etiological form of viral hepatitis is hepatitis A. The spread of hepatitis B and nondifferentiated hepatitis is less than that of hepatitis A. The ratio of different etiological forms of virus hepatitis is determined by the epidemiological situation. At the period of epidemic hepatitis A morbidity increases while hepatitis B morbidity decreases. The occurrence of nondifferentiated hepatitis at different periods of observation remains unchanged.
