Hepatitis A

Consider active immunization with hepatitis A vaccine or passive immunization with immune globulin (IG) for all susceptible travelers. Especially consider choosing active immunization for persons planning to reside for a long period or for persons who take frequent short-term trips to risk areas. The importance of protection against hepatitis A increases as length of stay increases. It is particularly important for persons who will be living in or visiting rural areas, eating or drinking in settings of poor or uncertain sanitation, or who will have close contact with local persons (especially young children) in settings with poor sanitary conditions.
