|Many people who learn they are HIV-positive
are testing for the first time, according to a new study.
Researchers from CDC analyzed data on persons age 13 and
older newly diagnosed with HIV from 2006 to 2009 in 18 jurisdictions taking
part in an HIV incidence surveillance system. Among participants for whom
previous testing history was available, 41 percent were diagnosed with the
virus at their first HIV test.
Fifty-nine percent of those found to be infected had
previously tested HIV-negative at some time. The groups with the greatest
proportions of persons testing HIV-negative less than 12 months before
learning they were HIV-positive included those ages 13-29 (33 percent),
males whose infection was attributed to sex with males (29 percent), and
whites (28 percent).
“Enhanced efforts are needed to increase annual HIV
testing for populations at high risk for HIV infection to increase early
detection,” CDC said.
