Modes of HIV Transmission

This topic covers the fundamental modes of HIV transmission, essential knowledge for all tertiary-level health science students in Zambia. It details the three primary routes: unprotected sexual intercourse (with a focus on heterosexual transmission as the most common in Zambia), contact with infected blood or body fluids (including through unsafe injections or transfusions), and mother-to-child transmission (MTCT) during pregnancy, delivery, or breastfeeding. Understanding these pathways is the first step in designing effective prevention strategies. For university and college students pursuing medicine, nursing, public health, or laboratory science, this foundational information is critical for exams and forms the basis for all subsequent learning in HIV epidemiology, counseling, and clinical management. It enables Zambian learners to accurately assess risk, provide evidence-based patient education, and contribute to targeted prevention efforts within their communities and future professional roles.
