"Transactional sex, sexual intercourse driven by material exchanges," occurs worldwide, but "[i]n poor regions with high HIV prevalence rates like sub-Saharan Africa ... transactional sex poses an even higher threat to one's wellbeing and health because the chance of HIV infection is greater," Daniella Choi, staff member at the Center for Strategic & International Studies, writes in CSIS' Commission on Smart Global Health Policy blog. "In addition to the existing HIV/AIDS interventions such as behavioral change, contraceptive promotion, and ARV treatments, a renewed focus on economic empowerment is necessary. When women are financially independent, the need to use sex as currency or tolerate sexual infidelity is reduced," she writes (8/10).
