To address the international Human Immunodeficiency Virus epidemic, the World Health Organization, or WHO, developed three drug treatment regimens between 2010 and 2012 specifically for HIV-positive pregnant women and their infants. WHO developed the regimens, calling them Option A, Option B, and Option B+, to reduce or prevent mother-to-child, abbreviated MTC, transmission of HIV. Each option comprises of different types and schedules of antiretroviral medications. As of 2018, WHO reported that in Africa alone about 1,200,000 pregnant women were living with untreated HIV. Those women have up to a forty-five percent chance of transmitting HIV to their offspring if they do not receive treatment. Option B+ has decreased the overall maternal mortality rates in many low- and middle-income countries, and numerous studies have supported the notion that it is the most effective of the three regimens for preventing MTC transmission of HIV.
