The occurrence of viral hepatitis in Danish clinical chemical laboratories during a 10-year period was studied by repeated questionnaires. The overall incidence rate was 180 per 100,000 per year, roughly 7 times the figures for the general population, the excess frequency being found for technicians, student technicians as well as in cleaning staff. 90% of the cases studied were HBsAg positive. Two clusters of cases were associated with a haemodiolysis and a cancer chemotherapy unit, respectively. Otherwise the hepatitis risk was 3 times greater in the metropolitan area than in provincial towns. Within the last 3 years the incidence rate decreased to one quarter of previous rates. This change might be attributable to increased general attention and safety precautions.
通过重复问卷调查研究了丹麦临床化学实验室在10年期间病毒性肝炎的发生情况。总发病率为每年每10万人180例，约为普通人群发病率的7倍，技术人员、实习技术人员以及清洁人员的发病率都偏高。所研究病例的90%乙肝表面抗原呈阳性。分别有两例聚集性病例与血液透析和癌症化疗科室有关。此外，大城市地区的肝炎风险是省级城镇的3倍。在过去3年里，发病率降至之前的四分之一。这种变化可能归因于公众关注度的提高和安全预防措施的加强。
