Hepatitis A and B are hyperendemic in tropical and, to a lesser extent, subtropical countries. This high level of endemicity is in sharp contrast with the low frequency of these infections in the industrialized world. As a consequence, the incidences of hepatitis A and B are high among travellers to or foreigners living in tropical or subtropical countries. Therefore, these subjects should be vaccinated against hepatitis A and B. Furthermore, the usual preventive measures should be maintained. Risk of infection with the hepatitis C and E virus are much lower. Given the increasing number of travellers to tropical and subtropical countries, imported hepatitis is a public health problem for industrialized countries. Preventive measures must, then, be reinforced.
