LINKAGES is a USAID-funded project conducting a range of activities to reduce HIV transmission among key populations—sex workers, men who have sex with men, transgender persons, and people who inject drugs—and to improve their enrollment and retention in care.  LINKAGES will accelerate the ability of governments, organizations working with key populations at risk of HIV, and private-sector providers to plan and implement services that reduce HIV transmission among key populations and their sexual partners and extend the lives of those already living with HIV. FHI 360 leads the project in partnership with IntraHealth International, PACT, and the University of North Carolina at Chapel Hill.
