The “Centro de Atención ITS Zona 3” clinic in Guatemala City sees, on average, 70 patients every morning. They provide visitors – most of whom are female sex workers – family planning services as well as testing for HIV and other sexually transmitted infections. Key populations such as sex workers are at higher risk of getting infected with HIV. Thanks to Global Fund support, thousands of female sex workers in Guatemala have been tested for HIV, and thousands more have been reached with HIV prevention programs.
