National HIV Testing Week 2026

National HIV Testing Week 2026 is happening 9th to 15th February 2026 in the United Kingdom. However, submissions are welcome throughout the year (until the deadline shown) and from across the globe.

While HIV outcomes have improved substantially, important gaps remain in detecting acute and early infection, optimizing diagnostic pathways across care settings, and translating test results into timely, evidence-based treatment.

This Research Topic will showcase experimental, translational, and clinical studies that advance HIV diagnostics, deepen understanding of early pathogenesis and host–virus interactions, and improve therapeutic management after diagnosis. Contributions should prioritize mechanistic insight, clinical diagnosis and patient stratification, and innovations in therapy and care pathways.

Topics of interest include, but are not limited to:

• Innovations in HIV diagnostics and confirmatory testing algorithms, including approaches to identify acute/early infection.
• Diagnostic stewardship and clinically integrated testing-to-treatment pathways that enable rapid ART initiation.
• Host susceptibility, biomarkers, and prognostic markers relevant to disease course and treatment response.
• Early pathogenesis and reservoir establishment with implications for monitoring and outcomes.
• ART optimization, resistance testing, long-acting regimens, and management of co-infections, comorbidities, and pregnancy-related clinical considerations.
• Case reports/series addressing unusual presentations, diagnostic pitfalls, or therapeutic challenges.

This project aims to accelerate progress from HIV testing to durable viral suppression by advancing clinically meaningful diagnostics and therapy, ultimately improving outcomes for people living with HIV.
