This document discusses strategies to prevent and control the transmission of HIV/AIDS. It outlines several strategies used in Tanzania and other developing countries, including mass media campaigns, behavioral interventions, education and training for healthcare providers, school-based sex education, voluntary counseling and testing, peer-based programs, condom promotion and distribution, avoiding unwanted pregnancies among infected mothers through family planning services, use of antiretroviral therapy, feeding substitution to prevent mother-to-child transmission, and providing antiretroviral drugs to infected mothers to significantly reduce vertical transmission. The session aims to explain these prevention and control methods, their effectiveness and limitations, and reasons for the slow eradication of HIV/AIDS.
