Evidence of serosorting after diagnosis with acute HIV infection

Individuals with acute HIV infection employ a number of strategies in the weeks after their diagnosis to reduce the risk of passing on HIV to their sexual partners, according to a study presented to the US National HIV Prevention Conference on December 5^th. Investigators from the University of California, San Francisco found individuals with acute infection reduced their number of partners, abstained from sex, increased their use of condoms and deliberately selected new sexual partners who were perceived to be HIV-positive.

HIV-positive individuals are most infectious in the months soon after they are infected with HIV. This period is often called acute or primary HIV infection and research suggests that up to 50% of HIV transmissions are attributable to individuals with acute infection (although other investigators contest this finding).
