The risk of hepatitis B virus (HBV) infection for international travelers is generally low, except for certain inhabitants and long-term visitors to countries with high HBV incidence. Factors to consider when assessing risk include: 1) the prevalence of HBV carriers in the local population, 2) the extent of direct contact with blood, or secretions, or of intimate sexual contact with potentially infected persons, and 3) the duration of travel. Don't forget this disease is transmitted like AIDS: by needles, transfusions, and sexual activity. It is a different disease than Hepatitis A, which is a food and waterborne disease occurring because of fecal contamination.

Hepatitis B vaccination is available and recommended for all persons who work in health care fields.

It should also be considered for persons who plan to reside in endemic areas for greater than six months.

If that describes your situation, consult your physician. Vaccination needs pre-planning as it usually takes 3 to 6 months for the three- to four-part series.
