In 2019, Lombardy and Lazio were the Italian regions with the highest number of newly diagnosed HIV infections, with 544 and 356 cases, respectively.

HIV in Italy

In Italy, the number of new HIV cases fluctuated over time. The lowest number of cases was registered in 2008, when 2,482 individuals were newly diagnosed with HIV. However, in that time data from several regions were missing. Thereafter, the number increased and peaked in 2012, before gradually decreasing until 2019. HIV was more common among males than females. Moreover, the most affected age group was the one consisting of people who were 30 to 39 years old. As a matter of fact, in 2019, 549 males and 142 females in their 30s were newly diagnosed with HIV.
