人巨细胞病毒(HCMV)属疱疹病毒β亚属,核心为双股线性DNA病毒,免疫学检查提示多数人在幼年或青年期获得感染。国内外血清学检查显示健康人群HCMV抗体阳性率为40%～100%[1],说明HCMV在人群中的感染甚为普遍,且以隐性感染为主。HCMV感染人体经急性期至恢复期后,病毒可长期潜伏体内,当机体免疫功能受到抑制时,病毒可再次被激活而致病,部 Human cytomegalovirus (HCMV) is a beta subunit of herpesvirus, the core of which is a bilinear linear DNA virus. Immunological tests indicate that most people are infected in their infancy or adolescence. Serological tests at home and abroad showed that the positive rate of HCMV antibodies in healthy population was 40% ~ 100% [1], indicating that HCMV infection in the population is very common, and mainly invisible infection. HCMV infection in the human body from acute to convalescent, the virus can be long-term latent body, when the body’s immune function is suppressed, the virus can be activated again and the disease, the Department
