Effectiveness of a screening program for HBV, HCV, and HIV infections in African migrants to Sicily

subject

description

BACKGROUND Migrants from Africa are vulnerable to viral infections during their journey. METHODS Migrants who arrived in western Sicily were offered early screening for hepatitis B virus (HBV), hepatitis C virus (HCV), and human immunodeficiency virus (HIV) infection. A questionnaire was administered to evaluate risk factors, and antiviral therapy was offered to subjects with active infection. A multiple regression analysis and adjusted odds ratio were obtained to evaluate risk factors. RESULTS Overall, 2,639 of 2,751 (95.9%) migrants who arrived between 2015 and 2017 accepted screening and 1,911 (72.4%) completed the questionnaire. HBsAg was positive in 257 (9.7%) migrants, 24 (0.9%) were anti-HCV positive and 57 (2.2%) had HIV infection. The prevalence of HBV infection was higher in women (aOR 2.47,95%CI 1.90-3.20),p = 0.003) and in people who endured physical and/or sexual violence (aOR 2.24,95%CI 1.87-3.55,p<0.001), while HIV infection was more frequent in women (aOR 5.40,95%CI 3.09-9.43, p <0.001) who were in Libya for a long period (aOR 5.66,95%CI 2.90-10.70,p = 0.004) and endured physical and/or sexual violence (aOR 14.77,95%CI 8.34-22.11,p<0.001). Being older than 18 was associated with HCV infection (p<0.001). Overall, 77% of 57 subjects with HIV infection were retained in care, 79% of 70 chronic HBV hepatitis cases started nucleot(s)ide analogues and 61% of 18 HCV-RNA positive cases received direct-acting antiviral therapy. CONCLUSIONS These findings evidence the effectiveness and feasibility of infectious disease screening programs for migrants.
