Senegal has maintained one of the lowest rates of HIV infection in sub-Saharan Africa and has long emphasized prevention and primary healthcare. As in Uganda and Thailand, there was a unified response to HIV from the government and religious leaders. HIV prevention was included when sex education was introduced in schools, HIV voluntary and confidential counseling and testing were made available, condoms were promoted to sex workers and their clients, and STI care was integrated into regular primary healthcare services. As these interventions were introduced, rates of all STIs measured among pregnant women in Dakar dropped dramatically.
