“…In Europe, more than half of 49 million migrants born outside of the European Economic Area came from nations where HBV endemicity is either intermediate (2–8%) or high (>8%), explaining the higher prevalence of HBV infection in migrants (5%), and asylum seekers (10%) compared to the general population (1%) in Europe ( European Centre for Disease Prevention and Control, 2016 ; Kim et al, 2021 ; Table 1 ). Descriptive studies from Italy and the UK provide some insight into HBV infection among migrants and unaccompanied asylum-seeking children ( Table 2 ; Prestileo et al, 2022 , Colucci et al, 2022 ; Mazzitelli et al, 2021 ; Armitage et al, 2022 ; Williams et al, 2020a , World Health Organization, 2002 ), reporting risks of infection that apply before, during and after relocation ( Figure 1 ). In some countries, including the UK, asylum seekers may be moved hundreds of miles away at short notice, disrupting any continuity of care ( Farrant et al, 2022 ; World Health Organization, 2018b ).…”
