But there is good news for them, too!

"CDC’S December 2015  “VITAL SIGNS” estimated that  25 percent of sexually active gay and bisexual men, nearly 20 percent of  adults who inject drugs, and less than one percent of heterosexually active adults are at substantial risk for HIV infection."

And they are down to less than 40,000 diagnosed cases in 2015!
