目前已知,人感染乙型病毒性肝炎后,其唾液、阴道分泌物或精液中都可检出乙型肝炎表面抗原(HBsAg),而且通过一定的途径如性交、接吻,甚至人的咬伤等,还可能造成乙型肝炎病毒的传播。为了证实精液和唾液的传染性及可能的传播途径,作者用长臂猿进行了感染试验。精液采用慢性活动性肝炎患者,HBsAg/adw、HBeAg和抗-HBc均阳性;唾液则采自2名HBeAg和HBsAg/adw携带者,滴度1:1000以上,而且从唾液中检出
It is now known that hepatitis B surface antigen (HBsAg) can be detected in saliva, vaginal secretions or semen after being infected with hepatitis B virus and is also detected by some means such as intercourse, kissing and even human bites Etc., may also cause the spread of hepatitis B virus. In order to confirm the semen and saliva infectivity and possible routes of transmission, the authors used gibbons for infection tests. Semen was positive in patients with chronic active hepatitis, with positive for HBsAg / adw, HBeAg and anti-HBc; saliva was collected from 2 HBeAg and HBsAg / adw carriers with titer above 1: 1000 and was detected in saliva
