Symptoms or problems that developed during travel and that have not subsided by the time a person has returned home warrant medical attention. Travel-related problems also can develop after travel. For example, nitrogen narcosis (the bends) can occur after a diver gets on the plane to go home (see Diving and Compressed Air Injuries: Decompression Sickness). Some symptoms may develop weeks or months after a person has returned. Fever after international travel is especially common. For example, malaria often causes fever days after exposure. Although the connection between travel and new symptoms often is not apparent, information about recent travel can be the key element in making a diagnosis. Therefore, people should tell their doctor about any recent travel when experiencing any medical problem.
Both the International Society of Travel Medicine (www.istm.org) and the American Society of Tropical Medicine and Hygiene (www.astmh.org) have lists of travel clinics on their web sites. Many of these clinics specialize in assisting travelers who are ill after their return home.
