Why this survey?

Despite significant progress in prevention in recent years, the epidemiological situation regarding HIV and STIs remains a cause for concern among men who have sex with men. They account for 42% of HIV diagnoses reported in 2024 and are also disproportionately affected by other sexually transmitted infections.

Objectives and expected results

The ERAS survey has been conducted via an online questionnaire every 2 to 3 years since 2017 and aims to better understand the prevention strategies of men who have sex with men.

The results of this survey are used to tailor prevention messaging for men who have sex with men to help them adopt various prevention tools and adapt prevention services to their needs.
