According to @brookenichols at #IAS2025, self-test-based PrEP continuation could offset the costs of bespoke programming for groups like MSM and female sex workers, allowing services to be maintained even amid funding cuts.

Ines Dourado from @UFBA and the Unitaid-funded PrEP-1519 project emphasizes that introducing self-testing is not just a technical fix: it’s a structural opportunity to simplify PrEP delivery, expand reach and reduce the clinical burden in overstretched health systems. #IAS2025

Christian Stillson of @CHAI_health reminds us: HIV self-testing has evolved from a diagnostic tool to a cornerstone of PrEP access. As we scale long-acting PrEP, self-testing will be critical to reaching more people, faster and more efficiently. #IAS2025

According to Dr. Lloyd Mulenga, self-testing isn’t just a backup, it's central to the future of HIV prevention. By embedding it in community settings and national guidelines, Zambia is shifting how prevention reaches those most at risk. #IAS2025

At #IAS2025, @WHO’s Michelle Rodolph highlighted the importance of long-acting injectable PrEP, such as lenacapavir, as an added option for HIV prevention. Expanding access to more methods gives people real choice and supports better health outcomes.

People living with HIV are at higher risk of severe #mpox. Knowing your HIV status and starting antiretroviral therapy is very important. The new mpox guideline strongly recommends testing for HIV in people with mpox and starting antiretroviral therapy without delay. 🔗 bit.ly/43YOzjf

A great scientific signal towards another medical tool for #HIV prevention and protection. @WHO's guidance for LEN PrEP twice-a-year dose is in development. If the trial for a yearly dose concludes successfully, WHO guidance will be rapidly adjusted. xitter.cf/bbcworld/status/189951…
