• Comprehensiveness of mandatory reporting (MR) and participation in LaboVIH:

  • Continued improvement in the overall completeness of mandatory reporting (MR) in 2024: 81%

  • Laboratory participation in this survey, which helps address the lack of completeness in HIV mandatory reporting, remains high in 2024: 90%

• HIV Testing (LaboVIH / SNDS / VIH Test): In 2024, continued strong increase in testing across all age groups already observed in 2023, linked to the accelerated rollout of the VIHTest and Mon Test IST (HIV without a prescription) programs

• HIV diagnosis (SO):

  • Decrease in 2024 in the rate of HIV-positive diagnoses (regardless of the date and place of infection), except among MSM born abroad (stable)

  • Men who have sex with men (MSM) account for 63% of HIV diagnoses in 2024, more than in mainland France excluding the Île-de-France region (44%)

  • The proportion of early diagnoses is higher than in mainland France excluding the Île-de-France region, particularly in Hérault, followed by Gard

• HIV incidence and size of the undiagnosed population:

  • The number of new infections in Occitanie (including both diagnosed and undiagnosed individuals, excluding those infected prior to arriving in the region) was estimated at 160 [95% CI: 101–218] in 2024, and is trending downward compared to 2023

  • The number of people living with HIV in Occitanie who are unaware of their HIV status was estimated at 513 [95% CI: 434–593] at the end of 2024. Among them, the proportion of MSM born in France was 40%, that of heterosexuals born in France was 22%, and that of heterosexuals born abroad was 23%

• Diagnosis: Stable rate of Ct infection diagnosis since 2021 (88.3 per 100,000 people aged 15 and older), despite the increase in screening rates
