Lisa Bohmer worked as the HIV/AIDS Director for UNICEF in Ethiopia and presented on challenges and opportunities for preventing mother-to-child transmission of HIV/AIDS in Africa. Key points included: HIV transmission can occur during pregnancy, labor, delivery or breastfeeding; Ethiopia faces high infection rates particularly among young people and women; and challenges include stigma, improving safer birthing practices, counseling on infant feeding options, and ensuring a steady supply of drugs and testing kits. Opportunities lie in increased funding, integrating PMTCT into other health programs, and engaging communities to promote testing and reduce stigma.
