Traveler's Diarrhea Understanding

Traveler's Diarrhea Overview, Country-Specific Treatment Guidelines and Diagnosis

Traveler’s diarrhea refers to a common travel-related illness. It typically describes a gastrointestinal infection after consuming contaminated food or water in an area that is not local to the person traveling.  Diarrhea is characterized by abnormally loose or watery stools.  Health experts may define a Traveler’s diarrhea as 3 or more loose stools in a 24-hour period during a trip abroad to a country with different hygiene practices. It often presents with other symptoms, such as nausea and vomiting. The onset of symptoms may be during or within 10 days of travel and typically lasts for 3–5 days.

Less severe symptoms include nausea, vomiting, fever, bloating, excessive gas, loss of appetite, and an urgent need to defecate, whereas these symptoms can also become severe which will indicate an urgency to immediately consult a health practitioner and severe symptoms include: severe, intolerable pain in the abdomen or rectum, persistent vomiting for more than four hours, resulting in the inability to keep liquids down, fever higher than 102˚F, bloody stools, symptoms of dehydration.

The Travelers' Diarrhea report provides an overview of Travelers' Diarrhea pathophysiology, diagnostic approaches, and detailed treatment algorithm along with a real-world scenario of a patient’s journey beginning from the first symptom, the time taken for diagnosis to the entire treatment process.

Further details related to country-based variations in diagnosis are provided in the report..

Travelers' Diarrhea Treatment

In many cases, symptoms of Travelers' Diarrhea resolve in a few days. As such, treatment often involves fluid replacement to avoid dehydration.
