The effectiveness of a serosorting strategy for HIV prevention depends on the accuracy of individuals’ serostatus disclosures. We modeled the risks of sexual transmission of HIV under various circumstances differing by the type of disclosures made. Accounting for rates of unrecognized HIV infection, treatment status and differences in infectivity by stage of infection, we found that serosorting can increase the transmission risk for some groups.
