WASHINGTON — About 250,000 Americans are HIV positive but unaware of it, according to a Centers for Disease Control and Prevention study released Thursday, and most of them are not in high- risk groups.
“In the past, people associated HIV with drug use and men who have sex with men,” said Bernard Branson, associate director for laboratory diagnostics in the CDC’s division of HIV/AIDS prevention. “But the epidemic is changing, and there is an increased proportion of cases that have been reported in heterosexual transmissions and among women.”
Branson said that efforts to test people who are in high- risk groups for HIV have been successful. To reach the remaining 25 percent of Americans who are HIV positive but don’t suspect it, however, efforts have to be broadened, and quickly, Branson said. An HIV-positive person who doesn’t know it is three and a half times more likely to transmit the infection than someone who does, he said.
