Fever after International Travel

The common medical problems that are encountered after international travel (particularly after returning from a developing country) are diarrhea, fever, respiratory infection, skin diseases etc. to name a few. For proper diagnosis of the cause of fever after international travel, a detailed history should be taken, focusing on the traveler’s exact itinerary, including dates of arrival and departure, exposure history (food indiscretions, drinking-water sources, freshwater contact, sexual activity, animal contact, insect bites), location and style of travel (urban or rural travel, first-class hotel accommodation or camping), immunization history; and use of anti-malarial prophylaxis etc. For proper diagnosis some knowledge of geographic medicine, particularly the epidemiology and clinical presentation of infectious diseases are essential.

Gravity of fever in a traveler:

Fever in a traveler after travel to a malarious area should be considered a medical emergency because death can occur from P. falciparum malaria following an illness of only few days duration. In a traveler with fever malaria should be first diagnosis considered (other important causes of fever after travel include viral hepatitis A and E, typhoid fever, bacterial enteritis, arboviral infections like dengue fever, rickettsial infections including tick and scrub typhus and Q fever, and acute HIV infection, and amebic liver abscess), though “fever from the tropics” does not always have a tropical cause like malaria or other tropical infectious disease. The risk of P. falciparum malaria is highest among travelers those who become develop fever within the first 2 months after return, especially return from Africa or Oceania.

A surveillance study by CDC and the International Society of Travel Medicine showed that among travelers developing fever after return from international travel, malaria was acquired most often from Africa, dengue from Southeast Asia and the Caribbean, typhoid fever from southern Asia, and rickettsial infections like tick typhus from southern Africa.
