Fundación Huésped

Fundación Huésped is an Argentine health NGO, active since 1989, that works on HIV, viral hepatitis, sexual health and other infectious diseases. Its Buenos Aires base is at Av. Forest 345 in Chacarita, and it publishes information on HIV testing, PrEP, PEP and prevention on its website, huesped.org.ar. For visitors it is the most useful address for sexual-health questions, including where to find free testing in the city.
