UNITED STATES: "A Good Report on AIDS, and Some
Credit the Web"
New York Times (08.18.04):: Dean E. Murphy
San Francisco health officials say numerous factors could explain preliminary figures from a June CDC report which estimates the ity's rate of new HIV infections among men who have sex with men
(MSM) is 1.2 percent per year, rather than the city's previous 2.2 percent estimate.
Some city officials credit more regular testing and harm-reduction
strategies to discourage crystal methamphetamine use,
which is blamed for reducing inhibitions and fueling risky sex. But in addition, there are signs that MSM are serosorting - choosing sex partners with the same HIV-serostatus. Various Web sites have proliferated where HIV-positive MSM can meet prospective sex partners who are also seropositive. At scores of
educational meetings, workshops, seminars, and parties, San Francisco MSM are talking about "responsible sex," which may not
necessarily include condoms but does involve serosorting.
As several HIV-positive men at a meeting organized by
the nonprofit Stop AIDS Project (SAP) in San Francisco acknowledged, serosorting relies on honest disclosure - and knowing one's true HIV status. That is easier in San Francisco, say health officials: CDC estimates that 77 percent of HIV-positive men in San Francisco know they are infected, compared with 48 percent of those infected men in New York and 38
percent in Baltimore.
San Francisco's latest HIV infection rate is its lowest since 1997 and is the lowest of five US cities studied by CDC, which did not explore causes behind the decrease. Preliminary results on 1,767 MSM tested from June 2004 to April 2005 found that new HIV ncidence among MSM was 8 percent in Baltimore, 2.6 percent in Miami, 2.3 percent in New York and 1.4 percent in Los Angeles. CDC's data were further supported by more recent preliminary San Francisco clinic data and surveys of MSM by the nonprofit SAP.
"Studies have shown when people have knowledge of
their serostatus, they take that knowledge and use it to protect their partners," said Dr. Patrick S. Sullivan, CDC's chief of behavioral and clinical surveillance. Health officials recommend safe-sex practices regardless of partner.  |
