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.
首次对哈巴罗夫斯克（位于远东地区）病毒性肝炎的病因结构进行了研究。病毒性肝炎的主要病因形式是甲型肝炎。乙型肝炎和未分化型肝炎的传播程度低于甲型肝炎。病毒性肝炎不同病因形式的比例由流行病学情况决定。在甲型肝炎流行期间，其发病率上升，而乙型肝炎发病率下降。在不同观察期，未分化型肝炎的发病率保持不变。
