Pregnancy is a physiological situation that requires specific and careful preparation before travel. Malaria, dengue fever and viral hepatitis E are more severe in pregnancy and at higher risk of adverse obstetrical outcome. Medical and obstetrical contra-indications to travel should be listed during pre-travel evaluation. Vaccine indications are the same as in the general population, and must be discussed after a rigorous benefit-risk analysis. Pregnant women should avoid or delay travel in areas of high malarial chloroquino-resistance.
