Is this trial a fit for you?
✓Likely a good fit
Ideal candidates are individuals aged 14-55 who are at risk of contracting HIV and willing to participate in regular testing and follow-up.
✕Probably not a fit
Patients who are not at risk for HIV or those who are already diagnosed with HIV and not willing to engage in the study's follow-up may not benefit.

What this trial studies
This observational study aims to gather data on the incidence of new HIV infections among individuals at risk across multiple international sites. Participants aged 14-55 who are vulnerable to HIV will be enrolled and evaluated every 12 weeks for HIV and other sexually transmitted infections (STIs). Those diagnosed with HIV will undergo further assessments to monitor viral load and treatment efficacy, with a focus on maintaining viral suppression. The study also aims to facilitate future recruitment into interventional studies targeting HIV remission.
Why it matters
Potential benefit: If successful, this study could enhance understanding of HIV transmission dynamics and improve strategies for prevention and treatment.
How similar studies have gone: Other observational studies have shown success in understanding HIV transmission, making this approach both relevant and potentially impactful.
