Vertical Transmission of HIV from Parent to Child
The terms used to describe HIV transmission from parents to their children include
HIV can be transmitted from an infected mother to her child during pregnancy, during labor and delivery, or through breastfeeding. Without intervention, such as antiretroviral therapy, the percentage of infected women’s children who are not breastfed and who become HIV+ ranges between 15% and 30%. Among children who are breastfed by HIV+ mothers, the percentage that becomes HIV+ increases to 25-45% (4). In other words, breastfeeding increases the chances of HIV transmission from an HIV+ mother to her child.
Worldwide Vertical Transmission Rates
Vertical transmission of HIV has been virtually eliminated in the developed world. But rates remain high in resource-constrained countries, particularly sub-Saharan African countries, where the vast majority of HIV-infected women of childbearing age reside. These high rates are largely due to these women’s lack of access to existing prevention interventions, including voluntary counseling and testing (VCT), replacement feeding (that is, using formula instead of breast milk), selective Caesarean section (which reduces the chances of HIV transmission by eliminating labor and delivery), and antiretroviral drug therapy (5).
Human Rights Issues for Women Relating to Parent-to-Child Transmission
Most young children with HIV/AIDS acquire the virus through their mothers. The main reason to test women for HIV during pregnancy or childbirth is to prevent transmission from mother to child by using antiretroviral therapy. However, it is often the case that with the focus so intently on the child, the mothers receive far from adequate or appropriate care. In many cases, no one explains to the mothers why they are being tested for HIV, and no one gives them information after the test (1). Women who are found to have HIV are sometimes stripped of their rights by being coerced into abortion or sterilization (1).
