Symptoms or problems that develop during travel and that do not subside by the time a person returns home warrant medical attention. Some disorders that people get during travel do not show up until after they return home.
The most common medical problem after travel is
Persistent traveler's diarrhea
The most commonly acquired potentially serious diseases are
Sexually transmitted infections, including HIV infection
Some travel-related problems can begin after travel. 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.
The International Society of Travel Medicine (www.istm.org) has lists of travel clinics. Many of these clinics specialize in assisting travelers who are ill after they return home.
