三、母儿间的巨细胞病毒感染孕妇感染巨细胞病毒,主要是通过接吻和性交,这是一种全身性疾病,多呈隐性感染,偶见发热、黄疸、肝肿大等,称为巨细胞性包涵体病,极易传播给胎儿,使之发生先天性巨细胞病毒感染。巨细胞病毒垂直传播的途径主要有三:①子宫内感染,巨细胞病毒可通过胎盘侵袭胎儿,尤以妊娠早期的感染率最高,妊娠后期通常不引起胎儿感染;②产道感染,隐性感染的孕妇,在妊娠后期巨细胞病毒被激活,从子宫颈等部位排出,在分娩过程中胎儿经软产道时,因接触或吞咽含有巨细胞病毒的宫颈分泌物、母血而感染;③出生后感染,产妇唾液、乳汁和尿
Third, cytomegalovirus infection between pregnant women Pregnant women infected with cytomegalovirus, mainly through kissing and intercourse, which is a systemic disease, mostly latent infection, occasionally fever, jaundice, hepatomegaly, etc., known as Giant cell inclusion body disease, easily transmitted to the fetus, making it a congenital cytomegalovirus infection. The vertical transmission of cytomegalovirus there are three main ways: ① intrauterine infection, cytomegalovirus can affect the fetus through the placenta, especially in early pregnancy the highest infection rate, late pregnancy usually does not cause fetal infection; ② birth canal infection, latent infection in pregnant women , Late in pregnancy, cytomegalovirus is activated from the cervix and other parts of the discharge in the process of childbirth through the fetus when the fetus due to contact or swallow with cytomegalovirus cervical secretions, maternal blood infection; ③ post-natal infection, Maternal saliva, milk and urine
