Winston Zulu—a worldwide HIV/AIDS activist and the first Zambian to openly talk about his HIV-positive status—has died, according to a UNAIDS statement. Zulu founded the Positive and Living Squad, the first organization of people with HIV in Zambia, which effectively launched one of Zambia’s first nongovernmental organizations. He was a global advocate for HIV prevention and access to treatment and care, as well as for issues related to tuberculosis and TB/HIV coinfection, and for human rights in general.
