Arri\u00e8re-plan<\/h3>\n\n\n\n

Dans les pays o\u00f9 la pr\u00e9valence initiale des virus de l'h\u00e9patite B et C (VHB et VHC) est faible, une forte migration peut influencer la charge de morbidit\u00e9 li\u00e9e \u00e0 l'h\u00e9patite virale. Le d\u00e9pistage et le traitement des migrants requi\u00e8rent des m\u00e9thodes et une approche diff\u00e9rentes de celles des programmes de d\u00e9pistage g\u00e9n\u00e9ralis\u00e9s. Notre objectif \u00e9tait d'estimer la pr\u00e9valence du VHB et du VHC chez les migrants dans les 27 pays de l'UE en 2024. La crise des r\u00e9fugi\u00e9s ukrainiens a \u00e9galement \u00e9t\u00e9 quantifi\u00e9e.<\/p>\n\n\n\n

M\u00e9thodes<\/h3>\n\n\n\n

\u00c0 partir des donn\u00e9es des Nations Unies sur les stocks de migrants de 2024, nous avons estim\u00e9 la population migrante de chaque pays de l'UE-27 par cohortes quinquennales d'\u00e2ge et de sexe, selon le pays de naissance. Ces r\u00e9partitions ont \u00e9t\u00e9 multipli\u00e9es par les estimations de pr\u00e9valence quinquennales par \u00e2ge et par sexe issues des mod\u00e8les de pays de naissance de l'Observatoire Polaris. La diff\u00e9rence entre les stocks de migrants ukrainiens de 2024 et de 2020 a \u00e9t\u00e9 quantifi\u00e9e afin d'estimer l'impact de la crise des r\u00e9fugi\u00e9s ukrainiens.<\/p>\n\n\n\n

R\u00e9sultats<\/h3>\n\n\n\n

En 2024, on estimait \u00e0 1,73 million (IC\u00a0: 1,04\u20132,66 millions) le nombre de migrants porteurs du VHB et \u00e0 1,03 million (IC\u00a0: 757\u00a0000\u20131\u00a0559\u00a0000) celui des migrants porteurs de l\u2019anti-VHC dans l\u2019UE-27, ce qui correspond \u00e0 des pr\u00e9valences respectives de 2,731\u00a0TP3T (IC\u00a0: 1,6\u20134,21\u00a0TP3T) et de 1,531\u00a0TP3T (IC\u00a0: 1,2\u20132,51\u00a0TP3T). La crise des r\u00e9fugi\u00e9s ukrainiens aurait entra\u00een\u00e9 l\u2019arriv\u00e9e de 43\u00a0000 migrants suppl\u00e9mentaires (IC\u00a0: 28\u00a0700\u201360\u00a0900) porteurs du VHB et de 154\u00a0000 migrants suppl\u00e9mentaires (IC\u00a0: 12\u00a0500\u2013202\u00a0000) porteurs du VHC dans l\u2019UE-27.<\/p>\n\n\n\n

Interpr\u00e9tation<\/h3>\n\n\n\n

La pr\u00e9valence de l'h\u00e9patite B et C chez les migrants et les communaut\u00e9s les plus touch\u00e9es au sein de l'UE-27 pr\u00e9sentent une grande h\u00e9t\u00e9rog\u00e9n\u00e9it\u00e9 au niveau national. Ces donn\u00e9es permettent aux d\u00e9cideurs politiques de mieux appr\u00e9hender les difficult\u00e9s rencontr\u00e9es par leur communaut\u00e9 et ainsi d'adapter leurs supports et leurs actions de sensibilisation aux r\u00e9alit\u00e9s culturelles. Malgr\u00e9 les nombreuses incertitudes concernant le nombre de migrants par pays et la pr\u00e9valence de ces infections au sein de ces groupes, cette \u00e9tude oriente les recherches sur les groupes les plus susceptibles d'\u00eatre impact\u00e9s \u00e0 l'\u00e9chelle de l'UE-27 et au niveau national.<\/p>\n\n

Summary Background In countries with low baseline burdens of hepatitis B and C viruses (HBV, HCV), high levels of migration can impact the burden of viral hepatitis. The screening and treatment of migrants requires different methods and sensitivities than broad-based programs.
