Deen L, et al. - Considering that migrants represent a considerable proportion of HIV diagnoses in Europe and are considered a group at risk of late presentation, the incidence of HIV diagnoses and the risk of late presentation were examined according to migrant status, ethnic origin and duration of residence. A historically prospective cohort study comprising all adult migrants to Denmark between 1.1.1993 and 31.12.2010 (n = 114.282), matched 1:6 to Danish born by age and sex was performed. In this work, migrants displayed a higher incidence of HIV diagnoses and late presentation compared with Danish-born. The incidence remained surprisingly high over time.
