Some travel-related problems can begin after travel. For example, decompression illness (the bends) can occur after a scuba diver surfaces. Scuba divers should not fly for 24 hours after diving, as this increases risk. 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 they experience any medical problem.
