New York Knows is the nation’s largest HIV testing initiative. It aims to help all New York City residents learn their HIV status and take full advantage of the City’s HIV care and prevention services. The program grew out of a successful large-scale borough-wide initiative, Bronx Knows, to increase voluntary HIV testing in the Bronx. Through New York Knows, the New York City Health Department partners with community-based organizations, community health centers, hospitals, colleges, universities, faith-based organizations and businesses. Resources are also available in Spanish.
