HIV-infected women remain fertile, although in late stages of HIV disease a pregnant woman may have a higher risk of miscarriage. Normally, the risk of transmitting HIV to the unborn child is between 15 and 30%. However, this may be reduced to just 2–3% if patients carefully follow medical guidelines.

HIV-positive people, seropositive people or people who live with HIV [1] are people infected with the human immunodeficiency virus (HIV), a retrovirus which if untreated may progress to acquired immunodeficiency syndrome (AIDS). According to estimates by the World Health Organization (WHO) and the Joint United Nations Programme on HIV/AIDS ...
HIV subtype variation and effect on progression rates. The HIV-1 subtype that an individual becomes infected with can be a major factor in the rate of progression from sero-conversion to AIDS. Individuals infected with subtypes C, D and G are 8 times more likely to develop AIDS than individuals infected with subtype A. [31] In Uganda, where ...
