IAS – The International AIDS Society leads collective action on every front of the global HIV response through its membership base, scientific authority and convening power.

Founded in 1988, the IAS is the world’s largest association of HIV professionals, with members in more than 170 countries. Working with its members, the IAS advocates and drives urgent action to reduce the impact of HIV. The IAS is also the steward of the world’s most prestigious HIV conferences: the International AIDS Conference, the IAS Conference on HIV Science, and the HIV Research for Prevention Conference. In light of the SARS-CoV-2 pandemic, IAS also convened two abstract driven COVID-19 conferences, in July 2020 and February 2021.
