For individuals at increased risk for HIV infection, how often may rescreening occur?

The recommendation for individuals at increased risk for HIV infection is rescreening every year. This is because of the dynamic nature of risk for HIV, especially in populations such as those with multiple sexual partners, those who engage in injection drug use, or those in areas with high HIV prevalence. Regular rescreening ensures that new infections can be identified promptly, allowing for timely interventions and reducing the risk of transmission further.

While the option indicating rescreening every 3 to 5 years may apply to individuals at lower risk, it is not sufficient for those with increased risk, who need more frequent testing due to their ongoing risk factors. The need for regular follow-up emphasizes the importance of early detection and prevention strategies in managing HIV risk.
