Reduction of Maternal-Infant Transmission of Human Immunodeficiency Virus with Zidovudine Treatment

In 1994, Edward M. Connor and colleagues published “Reduction of Maternal-Infant Transmission of Human Immunodeficiency Virus Type 1 with Zidovudine Treatment.” Their study summarized how to reduce the transfer of human immunodeficiency virus, or HIV, from pregnant women to their fetuses with Zidovudine, otherwise known as AZT. HIV is a virus that weakens the immune system by destroying white blood cells, a part of the body’s immune system. Fifteen to forty percent of infants born to HIV-positive mothers become infected during fetal development, labor and delivery, or breast-feeding. From April 1991 to December 1993, Connor and his colleagues researched HIV-positive pregnant women who took AZT, a drug that treats but does not cure an HIV infection. In their article, Conner and colleagues showed that AZT decreased the maternal-infant transmission of HIV and helped decrease infant mortality due to the viral infection.
