调查健康人群中是否存在狂犬病毒隐性感染及其隐性感染率。采集被调查对象的血清样本,用IFA法及其复核试验检测狂犬病毒抗体。在有犬伤史的126人中,隐性感染率为17.46%,抗体平均滴度为1:14.6;在有密切接触史的96人中,隐性感染率为23.96%,抗体平均滴度为1:10.3;在无受伤史、无接触史、无疫苗接种史的90人中,未检出狂犬病毒抗体。在健康人群中存在狂犬病毒隐性感染现象。
To investigate whether there is a latent infection rate of rabies virus and its latent infection rate among healthy population. Serum samples of the subjects were collected and rabies virus antibodies were detected by the IFA method and its review. In 126 dogs with history of wounds, the latent infection rate was 17.46% and the average antibody titer was 1: 14.6. Among the 96 persons with a history of close contact, the latent infection rate was 23.96%. The average antibody titer was 1: 10.3; rabies virus antibody was not detected in 90 patients without any history of injury, no history of exposure and no history of vaccination. There is a latent infection with rabies in healthy people.
