Information on the incidence of human immunodeficiency virus (HIV) and hepatitis B (HBV) and C (HCV) virus infections is needed for the planning of preventative measures against the spreading of these blood borne pathogens through treatment in the clinic. A survey was conducted to determine the incidence for 180 patients attending the maxillofacial and oral surgery clinic at the Medunsa Dental Hospital. Antibodies to HIV were found in 1.1 per cent. Hepatitis B surface antigen in 2.8 per cent and Hepatitis B core antibodies as the sole marker in three patients who tested positive for HBV-DNA. The prevalence of anti-HCV was 1.1 per cent. The presence of these infections indicates that there is a need for dental health care workers to comply with all recommended precautionary measures, including immunization against hepatitis B.
为规划通过临床治疗预防这些血源性病原体传播的措施，需要了解人类免疫缺陷病毒（HIV）、乙型肝炎病毒（HBV）和丙型肝炎病毒（HCV）感染的发病率。我们进行了一项调查，以确定Medunsa牙科医院颌面及口腔外科诊所180名患者的感染发病率。发现1.1%的患者存在HIV抗体。2.8%的患者存在乙型肝炎表面抗原，3名HBV-DNA检测呈阳性的患者仅以乙型肝炎核心抗体作为唯一标志物。抗HCV的患病率为1.1%。这些感染的存在表明，牙科医护人员需要遵守所有推荐的预防措施，包括接种乙肝疫苗。
