AIDS Walk Miami wants to change the course of the epidemic.
The 5K walk-a-thon started outside the Miami Beach Convention Center and ended at the Miami Beach Botanical Gardens.
"I come every year because I have friends that have it or have died from it," said participant Will Jackson.
About 1,500 people turned out for the 24th annual fundraiser Sunday morning benefiting Care Resource - considered the largest and oldest HIV/AIDS organization in South Florida.
It serves 15,000 people through services and outreach, including counseling, medical care and education.
Miami-Dade County has the highest number of AIDS cases per capita in the country. Broward county ranks second, according to the Florida Department of Health.
"People think not me," said Miami-Dade Commissioner Sally Heyman. "It's not that they're invincible they're just not conscientious about the risk in place."
The event offered free on-site HIV and STD testing through Care Resource Sunday.
AIDS Walk Miami raised at least $165,000 for Care Resource through its website (aidswalkmiami.org) and donations to participants.
