Objective: In Europe, during the last years the proportion of foreign migrants among AIDS and HIV cases is growing. In Italy, the number of new cases of HIV represented by foreign migrants has progressively increased, but the new HIV diagnoses incidence among foreign migrants has decreased, because of the increase in the total number of foreign migrants in recent years. Nevertheless, the new HIV diagnoses incidence among foreign migrants is still high if compared to that among Italians. The aim of the study was to analyze the characteristics of foreign migrants with a new HIV diagnosis and the new HIV diagnoses incidence among foreign migrants diagnosed in Italy between 2006 and 2013.
Methods: The new diagnoses incidence was calculated as the ratio between the number of new HIV diagnoses among foreign migrants and the number of foreign migrants residing in Italy. The new HIV diagnoses incidence was compared with that among Italians using the standardized incidence ratio (SIR) adjusted by age and gender.
Results: During the study period (2006-2013), of the 25,545 new diagnoses reported by the HIV surveillance system, 28.8% were among foreign migrants. The incidence of new HIV diagnoses among foreign migrants for the entire study period was 26.7 cases per 100,000 foreign migrant residents, compared to 5.1 per 100,000 among Italians. The incidence of new HIV diagnoses decreased over time for foreign migrants: from 42.5 per 100,000 foreign migrant residents in 2006 to 20.0 per 100,000 foreign migrant residents in 2013, whereas for Italians it remained stable. The SIR confirmed the marked difference between the two populations: specifically the overall incidence of new diagnoses was more than four times higher among foreign migrants, compared to Italians.
Conclusion: The results stress the need to reinforce the efforts aimed at reducing the circulation of HIV in this population.
