乙型肝炎病毒的传播径路多种多样,主要经注射和密切生活接触而传播。近年来发现生活的密切接触可能更为重要。唾液携带乙肝病毒,已被国内外学者们所注意,并报导乙肝病人及无症状携带者唾液中带有乙肝病毒表面抗原(HBsAg),进一步强调唾液传播的危险性。口腔医务工作者,有更多的机会接触乙肝病人和携带HBsAg的口腔病人,很易发生医院交叉感染。国内对乙肝病人,尤其无症状携带者的唾液中带有HBsAg,仅有数篇报导。我院于1986年11～12月,从各科门诊口腔病人、住院病人(简称口腔病人)中随机抽样,采取血液和唾液,并从我校传染科和市传染病医院采取已确诊为乙肝病人的唾液,进行HBsAg和乙肝病毒e抗原(HBeAg)的检测。
Hepatitis B virus spreads a wide range of routes, mainly by injection and close contact with life and spread. In recent years it has been found that life in close contact may be more important. Saliva to carry hepatitis B virus, which has been the attention of scholars at home and abroad, and reports of hepatitis B patients and asymptomatic carriers of saliva with hepatitis B virus surface antigen (HBsAg), further emphasizing the risk of salivary transmission. Stomatological workers, who have more access to hepatitis B patients and oral patients with HBsAg, are prone to hospital-acquired infections. Domestic hepatitis B patients, especially asymptomatic carriers of saliva with HBsAg, only a few articles. From November to December 1986, our hospital randomly sampled oral patients and inpatients (referred to as oral patients) from various departments to take blood and saliva, and from the Infectious Diseases and Infectious Diseases Hospital of our school, we took the patients diagnosed with hepatitis B Of saliva, HBsAg and hepatitis B virus e antigen (HBeAg) detection.
