According to the 'HIV Infection Report in Portugal – 2022', 1,803 new cases of HIV infection were diagnosed in the 2020-2021 biennium. Of these, 870 refer to 2020, and the remaining 933 to 2021.
The document, presented by the Directorate-General for Health (DGS) and the National Institute of Health Doctor Ricardo Jorge (INSA), reveals a 44% reduction in the number of new cases of HIV infection and 66% in terms of new AIDS cases between 2012 and 2021.
During the years 2020 and 2021, in particular, 415 new cases of AIDS were diagnosed.
In the same period of ten years, it was concluded that in 55.4% of the cases the diagnosis was late. And although the "heterosexual transmission" of the disease remains the most frequent (51.8%), cases in "men who have sex with men (MSM)" corresponded to the majority of new diagnoses in individuals of this sex (56,0%).
In 91.9% of cases diagnosed in these two years, transmission occurred through sexual intercourse, while cases of injecting drug users accounted for 2.3% of the total.
