International travelers frequently are at high risk of hepatitis B virus (HBV) infection simply because they do not understand how it is transmitted.
In a new study, researchers at the University of Zurich (Switzerland) Institute of Social and Preventive Medicine surveyed more than 9000 European travelers to determine their awareness of HBV transmission risks. Nearly 75% of the study participants had risk factors for contracting HBV, but only about half understood transmission routes, and just 17% were vaccinated against HBV.
