The epidemiological and clinical changes were documented by national surveys performed up to 2025, which provided an ongoing perspective on the long\u2010term evolution of HDV, highlighting the temporal trends in prevalence, risk factors, and clinical features. This review summarises the changes over time of HDV in Italy and the contemporary epidemiologic features of an infection that is vanishing among natives but increasing among migrants, outlining the medical challenge of a new heterogeneous clinical spectrum, including indolent phenotypes.<\/jats:p>","DOI":"10.1111\/jvh.70172","type":"journal-article","created":{"date-parts":[[2026,3,17]],"date-time":"2026-03-17T10:22:51Z","timestamp":1773742971000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":1,"title":["Changing
