title: [A clinical prospective study on maternal-fetal transfusion transmitted virus infection].
abstract: OBJECTIVE
  To observe the transfusion transmitted virus (TTV) infection rate in gravidas and parturients, and explore the route of maternal-fetal transmission.
  
  
  METHODS
  TTV infection was detected by nest-polymerase chain reaction (n-PCR) in the serum of 60 healthy gravidas and parturientes. Once parturient infection was identified, the latices and the umbilical blood were examined for TTV infection as well. Meanwhile, a group of non-pregnant healthy women was tested as control.
  
  
  RESULTS
  The infection rate of observation group was 28.33%, while in the control group it was 7.57%. The difference of the two groups was significant (P < 0.001). Of the TTV positive parturientes, TTV infection rate of their latices was 27.27%, but none of the umbilical blood samples showed TTV positive.
  
  
  CONCLUSIONS
  The TTV infection rate of gravidas and parturientes is higher than that of non-pregnant healthy women. TTV can infect newborns through latices, however, there is no vertical maternal-fetal transmission.
