TD is particularly common among people traveling to Asia (except for Japan and Singapore), the Middle East, Africa, Mexico, and Central and South America. The risk is moderate in Southern Europe, Russia, and China. TD has been linked to later irritable bowel syndrome and Guillain–Barré syndrome. It has colloquially been known by a number of names, including "Montezumas revenge," the "Nile runs" and "Delhi belly". Signs and symptoms
The onset of TD usually occurs within the first week of travel, but may occur at any time while traveling, and even after returning home, depending on the incubation period of the infectious agent. Bacterial TD typically begins abruptly, but Cryptosporidium may incubate for seven days, and Giardia for 14 days or more, before symptoms develop. Typically, a traveler experiences four to five loose or watery bowel movements each day. Other commonly associated symptoms are abdominal cramping, bloating, fever, and malaise. Appetite may decrease significantly. Though unpleasant, most cases of TD are mild, and resolve in a few days without medical intervention.Blood or mucus in the diarrhea, significant abdominal pain, or high fever suggests a more serious cause, such as cholera, characterized by a rapid onset of weakness and torrents of watery diarrhea with flecks of mucus (described as "rice water" stools). Medical care should be sought in such cases; dehydration is a serious consequence of cholera, and may trigger serious sequelae—including, in rare instances, death—as rapidly as 24 hours after onset if not addressed promptly. Causes
Infectious agents are the primary cause of travelers diarrhea.
Pachydermodactyly is a superficial dermal fibromatosis that presents as a poorly circumscribed symmetric, infiltrative, asymptomatic soft-tissue hypertrophy of the proximal fingers, typically sparing the thumbs and fifth fingers and rarely extending proximally to the wrists or occurring distally. : 990
