In 2018, Mike Ferraro was living on the street and sharing needles with other people who injected drugs when he found out he was HIV-positive. “I thought it was a death sentence, where you have sores and you deteriorate,” he said. Ferraro learned of his HIV status through a University of Miami Miller School of Medicine initiative called IDEA Exchange, which sent doctors and medical students to the corner where he panhandled. He got tested and enrolled in the program, which also provides clean syringes, overdose reversal medications, and HIV prevention and treatment drugs.
