This report presents HIV/AIDS surveillance data for 2022, a year marked by increased population movements1 across Europe that have had an impact on HIV trends, particularly in European Union/European Economic Area (EU/EEA) countries. In addition to the increased move￾ment of people, the post-COVID-19 recovery of health services and surveillance activities, and the scale-up and introduction of novel testing strategies in many countries resulting in the identification of previously undiagnosed cases, led to a significant rise in HIV diag￾noses across the Region. In 2022, 37 of the 49 countries in the Region, including 26 in the EU/EEA, reported an increase in HIV diagnoses compared to 2021, with some countries reporting record-high numbers in a single year.In 2022, 110486 HIV diagnoses were reported in 49 of the 53 countries in the Region, including 22995 from the countries of the EU/EEA. This corresponds to a crude rate of 12.4 HIV diagnoses per 100000 population in the Region overall, a slight increase on the rate for 2021 (11.9 per 100000 population). However, this represents a substantial decrease on the rate for 2019 (15.6 per 100000 population), which was the period before the COVID-19 pandemic (Table A, Figure A). When comparing the number of HIV diagnoses to the estimated number of new HIV infections over the past decade, it is evident that an increasingly larger number of individuals acquire HIV infection than are diagnosed.This indicates that the population of people living with undiagnosed HIV in the Region is growing (Figure A).
