An analysis of 11
previous HIV-related studies shows that HIV-positive
men and women who are tested and aware of their infections
are far less likely to engage in risky sexual behavior
than their infected peers who have not yet been
diagnosed. The analysis, published in the Journal of
Acquired Immune Deficiency Syndromes, examined
studies chronicling the sexual behavior of both men and
women who knew they were HIV-positive and those who
were shown through genetic tests to have been carrying
the virus for many months or longer but had not yet
been diagnosed as HIV-positive.
The analysis
shows that men and women aware that they are infected have a
53% lower incidence of unprotected vaginal or anal sex with
any partner, and 68% lower incidence with an
HIV-negative partner or a partner of unknown HIV
serostatus, than incidence levels reported by men and women
who were not yet aware they were HIV-positive. The
researchers say their findings highlight the
importance of encouraging sexually active adults to be
screened regularly for HIV infection because awareness that
one is infected greatly reduces risky sexual behavior
and significantly lowers the chances that the virus
will be passed to others through unprotected sex.
