Mother-to-child transmission of HIV is the major cause of HIV-infection in children especially in Africa and pregnancy among HIV-positive women is common among women on a prevention of HIV from mother-to-child transmission (PMTCT) programme and thus constitute a serious health risk to the child and to the general population. Results have shown that pregnant women on PMTCT programme seemed to know their HIV status prior to pregnancy and there are various factors associated with HIV-positive women becoming pregnant.
