The world's largest fundraising event for HIV and AIDS is happening in the city this weekend.

Thousands of people will gather in Central Park Sunday morning for the annual AIDS Walk New York.

People will walk to raise money for important programs at the GMHC, formerly Gay Men's Health Crisis.

Anchor Rocco Vertuccio spoke with Jason Cianciotto, the vice president of communications and policy at the GMHC, Saturday morning on NY1 to talk about the importance of the event.
