This paper aims at understanding the marriage situation of HIV infected pregnant women in Xinjiang by analyzing HIV infected cases，which were reported by the project of prevention of HIV maternal-neonatal transmission during 2010 to 2012，so as to provide reproductive health education for HIV infected women. The result shows that：The average age of 1 692 HIV infected women is 29.03，of which 53.31 % is 20～29 years old；the main route of transmission is sexual transmission (60.52 %)；most of them are first marriage，and 36.40 % of them are remarriage；pregnancy twice or more accounts for 70.69 %，even up to 10 times；delivery twice or more accouonts for 19.92 %. It can be found that the remarriage rate of HIV infected women in Xinjiang is higher than the other provinces，so it is very important to develop reproductive health education for HIV infected women.
