In 2011, Inga Kristen, Julius Sewangi, Andrea Kunz, Festo Dugange, Judith Ziske, Brigitte Jordan-Harder, Gundel Harms, and Stefanie Theuring published the article, “Adherence to Combination Prophylaxis for Prevention of Mother-to-Child-Transmission of HIV in Tanzania,” in PLoS ONE. Hereafter, “Adherence to Combination Prophylaxis,” the article details the authors’ investigation into the efficacy of a medication regimen called combination prophylaxis to prevent mother-to-child, or MTC, transmission of Human Immunodeficiency Virus, or HIV, before, during, and after delivery. They included pregnant women who had HIV, in Kyela, Tanzania. However, through interviews and surveys, the authors found that many women had difficulty adhering to the regimen, which made the medication less effective. Kristen and colleagues suggest that healthcare professionals who treat HIV-positive pregnant women increase hospital resources and prescribe medication to those women early in the pregnancy to reduce MTC transmission of HIV.
