Key Points

HIV Infections and AIDS

• HIV Surveillance

  • The two laboratories in Mayotte, one public (CHM) and the other private (Biogroup), participate in the LaboVIH survey, which provides insight into HIV testing activity

  • All mandatory reports have been the subject of at least one submission of a case report form, whether from the clinician or the laboratory

• HIV Testing

  • Source: LaboVIH:

    • The rate of HIV serology tests performed per 1,000 inhabitants has been slightly declining since 2021—110 HIV serology tests per 1,000 inhabitants in 2023

  • Source: SNDS (therefore covering only those enrolled in the social security system):

    • The highest screening rate was found among women aged 25 to 49

  • source: VIHTests:

    • The number of HIV tests has been rising sharply since September 2023, particularly among those aged 25–49

• HIV Diagnosis (DO)

  • The number of new HIV diagnoses was slightly down in 2023 (92 people), representing a rate of 296 per million, which remained very high and higher than that found in Île-de-France (173 per million)

• HIV incidence

  • The number of new HIV infections in 2023 was estimated at 37 people, representing a rate of 11.9 per 100,000 people, equivalent to that of Île-de-France

  • Approximately 140 people in Mayotte are unaware of their HIV-positive status

  • The median time between infection and diagnosis was estimated at 2.3 years

• AIDS Diagnosis

  • The number of AIDS diagnoses was estimated at 8 for 2023. It has been on the rise overall since 2014

Sexually transmitted infections caused by Chlamydia trachomatis (Ct), gonorrhea, and syphilis

• Screening

  • The screening rate, across all genders and ages, for these three conditions was increasing. The highest rate was found among women aged 26–49. For women aged 15–25, with the exception of syphilis, the rate was similar to that of other groups (men and women over 50), even though they are of childbearing age

• SNDS diagnosis (therefore concerning only those enrolled in the social security system)

  • The trends differed for these three conditions, with an upward trend for Chlamydia trachomatis and gonococcal infections, and a downward trend for syphilis

  • In 2023, the rate of positive diagnoses for these three conditions was primarily found among men aged 26 to 49
