Awareness and openness to the use of PrEP among a nationally representative sample of South African adults.

Introduction: South Africa adopted for pre-exposure prophylaxis (PrEP) in 2016, becoming the first African country to do so. Yet to date, uptake has been underwhelming, only about 165,000 South Africans were reported to be on PrEP in mid-2021. Lack of awareness has been cited as a contributory factor for the low uptake, but this has never been examined using a nationally representative sample.

Background: On December 20, 2019, the minimum age for purchasing tobacco in the US was raised nationally to 21 years. We evaluated this law (Tobacco 21 [T21]) 1 year after implementation.

Introduction: we examined HIV-related social norms and perceptions among South African adolescents aged 15-18 years and evaluated their openness to using pre-exposure prophylaxis (PrEP) to reduce HIV risk.
