The etiological structure of viral hepatitides among the adult population of Tallinn and the occurrence of markers of hepatitis B and hepatitis C virus infections in medical workers, addict introducing drugs intravenously and hemodialysis patients were studied. Changes in the etiological structure of viral hepatitides were established: they took the form of a decrease in the level of hepatitis A morbidity and the considerable growth of the role of hepatitides B and C, as well as the newly detected circulation hepatitis D virus. About one-third in the structure of morbidity in viral hepatitides were hepatitis cases without markers of hepatitis A, B or C viruses (non-A, non-B, non-C). The highest rates of hepatitis B virus infection (78.9%) and hepatitis C virus infection (82.5%) were detected among drug addicts. Their level of HBsAg was 8.8%. In the group of medical workers, 25% of the examinees, i.e. every fourth person, had markers of hepatitis B virus, while antibodies to hepatitis C virus were detected in 5% of cases. Among hemodialysis patients these rates were 21.4% and 10.7% respectively.
对塔林成年人群中病毒性肝炎的病因结构以及医护人员、静脉注射吸毒者和血液透析患者中乙型和丙型肝炎病毒感染标志物的出现情况进行了研究。确定了病毒性肝炎病因结构的变化：表现为甲型肝炎发病率水平下降，乙型和丙型肝炎的作用显著增长，以及新发现的丁型肝炎病毒传播。病毒性肝炎发病结构中约三分之一为无甲型、乙型或丙型肝炎病毒标志物的肝炎病例（非甲、非乙、非丙型）。在吸毒者中检测到最高的乙型肝炎病毒感染率（78.9%）和丙型肝炎病毒感染率（82.5%）。他们的HBsAg水平为8.8%。在医护人员组中，25%的受检者（即每四人中有一人）有乙型肝炎病毒标志物，而5%的病例检测到丙型肝炎病毒抗体。在血液透析患者中，这些比率分别为21.4%和10.7%。
