Generally, HIV prevalence is low across Western and Central Europe and North America with many countries reaching more than 80% of those in need of treatment.
Modes of transmission vary greatly by country. However, HIV disproportionately affects men who have sex with men and migrants from sub-Saharan Africa. In Europe, people who inject drugs, transgender people and sex workers are also at a heightened risk of HIV.
Too many people are diagnosed at a late stage of HIV infection, requiring the scaling up of HIV testing for earlier diagnosis and treatment.
