Malaria in migrants and travellers

Imported malaria is a growing problem in the world. In part this is a result of greatly increased and more rapid travel and in part a result of a resurgence of malaria in areas partially or completely cleared. Migrants, either refugees or those looking for better opportunities in life, have contributed to the movement of malaria to previously free areas. Failure of travellers to take appropriate action to prevent infection has contributed to the increased incidence of imported malaria. Vectors of malaria may also become travellers and thus contribute to the spread of infection.
