Number of HIV and AIDS diagnoses rising again
In 2024, the number of HIV and AIDS diagnoses in Belgium increased again by twelve percent compared to 2023. This is shown by figures collected by Sciensano. In 2024, there were 662 new HIV diagnoses, an average of 1.8 diagnoses per day. This new rise of twelve percent ends the declining trend of the past years.
In 2024, 19,325 people living with HIV were in medical follow-up in Belgium, a slight increase compared with 2022. The population of people in HIV care is ageing: 52% are aged 50 or older. In 2024, 289 HIV diagnoses were recorded among men who have sex with men (MSM), the same number as last year. Fifteen percent of these 289 MSM also reported sexual contacts with women.
Belgian MSM account for 56% of the new diagnoses, with an increase of 15% compared to 2023. European MSM represent 15%, Latin American MSM 14% and Sub-Saharan African MSM 7% of the new diagnoses among MSM. Among non-Belgian MSM, the number of diagnoses remained stable or slightly decreased compared to 2023. Most new diagnoses occur in the 30–39 age group, followed by 20–29-year-olds.
Among heterosexual people, there is also a rise of 13%, representing 332 HIV diagnoses. Among heterosexual women there is a slight decrease (-5%). For women of Belgian nationality, the number of diagnoses remained stable; for other nationalities, there was a slight decline.
Among heterosexual men, there was an increase of 13% compared to 2023. This rise is mainly seen among Belgian men, where the number of diagnoses went up by 33%.
Among heterosexual men, 39% had Belgian nationality, 35% Sub-Saharan African nationality, 18% European nationality and 9% another nationality.
One of the few positive signs in the Sciensano report is that more people are starting with PrEP medication. In 2024, 10,100 people used PrEP, an increase of 26% compared to 2023 (8,727). PrEP is especially popular among gay and bisexual men: 98% of PrEP users are MSM. These figures refer to dispensations in regular Belgian pharmacies; PrEP is also provided through hospital pharmacies.
