据 John P.Hansen 等人报道,Duke 大学从1977年1月到1980年4月,对医疗中心中接触血液制品和体液的全体职工作了普查。在这40个月中,有1235名职工接触血液制品或体液,其中155名出现 HBsAg 阳性,3名形成乙型肝炎。另有24名职工也患了乙型肝炎,但是却无明显的接触史。职工接触血液制品的方式主要是针刺、仪器污染、手指割破或外伤等。内科医师,特别是住院部医师因为接触机会较多,故得肝炎的危险最大 According to John P. Hansen et al., From January 1977 to April 1980, Duke University conducted a general survey of all workers in the medical center who were exposed to blood products and body fluids. During these 40 months, 1235 workers contacted blood products or body fluids, of whom 155 were HBsAg positive and 3 were hepatitis B. Another 24 workers also suffered from hepatitis B, but no clear history of exposure. Workers access to blood products mainly acupuncture, instrument contamination, finger cuts or trauma and so on. Physicians, especially inpatient physicians, are at greatest risk of hepatitis because of greater exposure
