Key points

HIV

• Increase in HIV testing activity (+5% in 2019 compared to 2018).

• This increase in testing activity in 2019 was accompanied by an increase in the number of confirmed positive serology results and a rise in the positivity rate of +23% compared to 2018 (1.6 per 1,000 tests performed).

• Men who have sex with men (MSM) born in France and heterosexuals born abroad remain the two most affected groups, accounting for 42% and 29%, respectively, of HIV-positive cases reported in 2019.

• An upward trend in the number of people aged 50 and older is observed among new HIV diagnoses, accompanied by a decrease in the proportion of early diagnoses. This trend will need to be confirmed with data from 2020.
