After sub-Saharan Africa, the Caribbean has the highest HIV/AIDS prevalence in the world. At the end of 2005, adult prevalence in the Caribbean was 1.6%—nearly three times higher than the United States, according to U.N. figures. More than 85% of the HIV-infected people in the region live on the heavily populated island of Hispaniola, home to both Haiti and the Dominican Republic. Heterosexual sex and migration drive the spread throughout the Caribbean, save for Puerto Rico's and Bermuda's serious HIV problems in injecting drug users.
