Serosorting for HIV prevention relies on accurate disclosure. This study found that serosorting may increase HIV transmission risk in certain populations due to factors like unrecognized infections.

Area of Science:

  • Public Health
  • Epidemiology
  • Infectious Diseases

Background:

  • Serosorting, a HIV prevention strategy, involves individuals choosing sexual partners based on their HIV status.
  • The effectiveness of serosorting is contingent upon the accuracy of self-disclosed HIV serostatus.

Purpose of the Study:

  • To model the risks of sexual HIV transmission under different serosorting disclosure scenarios.
  • To assess the impact of unrecognized HIV infections, treatment status, and infection stage on transmission risk within serosorting strategies.

Main Methods:

  • Mathematical modeling was employed to simulate HIV transmission dynamics.
  • The model incorporated variables such as rates of unrecognized HIV infection, current treatment status, and infectivity levels corresponding to different stages of infection.

Main Results:

  • Serosorting strategies can lead to an increased risk of HIV transmission for specific subgroups.
  • The accuracy of serostatus disclosure significantly influences the overall effectiveness and risk profile of serosorting.

Conclusions:

  • The findings highlight potential risks associated with serosorting, particularly when disclosure is inaccurate or incomplete.
  • Public health interventions should consider these risks and promote comprehensive HIV prevention approaches beyond serosorting alone.
