Acute Hepatitis Delta Virus Infection in Italy: Incidence and Risk Factors after the Introduction of the Universal Anti-Hepatitis B Vaccination Campaign

Abstract

Incidence of acute hepatitis delta infection is markedly decreasing in Italy. Undergoing invasive medical procedures, engaging in promiscuous sexual activity, and receiving beauty treatments are emerging, in addition to injection drug use, as important risk factors for infection. Further efforts are needed to increase vaccine coverage in high-risk groups and to implement the safety of invasive procedures performed both inside and outside health care facilities.
