This biennial conference presents the critical advances in basic, clinical and operational HIV research that move science into policy and practice. Through its open and inclusive programme, the meeting sets the gold standard of HIV science, featuring highly diverse and cutting-edge research.

Stay vigilant against scams! We have been alerted to cases of phishing emails impersonating the IAS 2025 “Global Travel Team” and targeting speakers. These emails are fraudulent. All official communication from IAS, the International AIDS Society, on behalf of IAS 2025 will come from an IAS 2025 email address, such as accommodation@ias2025.org. If you are unsure about an email or suspect a scam, please contact us at info@ias2025.org.
Language matters
At the IAS, we actively use language that puts people first. This is because words have power: they bestow or remove dignity, build or break stigma, and divide or unite the HIV response. Through the words we choose to use at the IAS, we acknowledge that a person is so much more than a condition; we promote inclusivity, dialogue and equality.

Inclusion is a priority for IAS 2025. We offer lower registration fees for delegates from upper-middle, lower-middle and low-income countries, as well as students, postdocs and young people.
