Objective To study the epidemiology of cytomegalovirus (CMV) infection in Qinba mountainous area Shaanxi Province China, where there was high prevalence of mental retardation(MR) in children. Methods 367 pregnant women in Qinba mountainous area were monitored with ELISA and PCR and presented with questionnaire. We detected the following: CMV-DNA in urine of 63 neonates born within two weeks whose mother infected CMV during pregnancy and CMV-DNA in breast milk post-delivery within two weeks of 61 women infected and 84 women non-infected. Results Infection rate of CMV in mental retardation prevalent area was 19.62%, the incidence of transmission in uterus was 33.33%, the incidence of excretion by breast milk was 39.34%, CMV infection during pregnancy relates to age, education, economic states, pregnant frequency and pathological delivery. It has no relation with gestational age. Conclusion The study points out that attention should also be paid to detecting CMV infection during pregnancy in mental retardation prevalence. Less education, worse financial condition, more frequent or pathological delivery should be regarded as high risk factors of CMV infection during pregnancy.
