Implementation of PrEP in Latin America.

Although many countries in Latin America have made progress in expanding access to HIV services, efforts to reduce the number of new HIV infections remain insufficient, with a 5% increase from 2010 to 2021.1 In Latin America, 54% of new HIV infections in 2021 were in men who have sex with men (MSM) and transgender women.1 Pre-exposure prophylaxis (PrEP) reduces the risk of HIV infection and is cost-effective in populations at risk. Yet, at the end of 2021, only 11 of 17 countries in Latin America provided some access to PrEP.
