Abstract : The incidence rate of hepatitis A is 3(6)/1 000 per month of stay in a developing country in unprotected travelers. Trampers and other persons feeding themselves under bad hygienic conditions have a rate of 20/1000. In many industrialized countries, persons below the age of 50 years have a seroprevalence rate of anti-HAV <20%. Hepatitis A morbidity and mortality in travelers is far greater than the one of any other vaccine preventable infection in travelers, with the exception that hepatitis B shows a slightly greater mortality in expatriates. Future studies will determine the role of hepatitis C and E.
