Traveler’s diarrhea is a common disorder among individuals who travel overseas to regions of limited resources.
It is also characterized as passing at least three unformed stools in 24 hours while simultaneously experiencing gastrointestinal disorder symptoms, such as nausea, vomiting, fever, cramping or abdominal pain, tenesmus, fecal urgency, or passing bloody or mucoid stools.
Although travelers’ diarrhea is usually self-resolving, it can cause dehydration and, in chronic cases, severe complications. Bacterial, viral, and parasite infections cause symptoms, although bacterial infections are the most common.
Epidemiology
The estimated incidence rate of travelers’ diarrhea is about 30-60%. It varies with geographical regions, with most incidence observed in the Sub-Saharan African region, followed by the Middle East, South Asia, and Latin America. In resource-limited regions, risk factors are often associated with poor hygiene.
Poor hygiene standards in food preparation and handling, absence of refrigeration, insufficient electrical supply, and poor food storing methods are significant causative factors.
Pregnancy, younger children or elderly travelers with pre-existing gastrointestinal disorders, or immunocompromised individuals are also risk factors for severe complications.
Anatomy
Pathophysiology
Traveler’s diarrhea is most transmitted through the fecal-oral route of the infectious agent, which occurs most commonly through the intake of contaminated water or food. The incubation span differs based on the causative agent, ranging from 6 -24 hours for viruses and parasites for 1-3 weeks.
The pathophysiology of travelers’ diarrhea varies according to the causal organism, but it can be divided into a non-inflammatory and inflammatory processes. Non-inflammatory agents reduce the intestinal mucosa’s absorptive capacities and increase the gastrointestinal tract’s output.
Inflammatory agent damages the intestinal mucosa through direct penetration of the mucosa or cytotoxic release. The erosion of the mucosa surface leads to a reduction in absorption and an increase in bowel movements.
Etiology
The cause of travelers’ diarrhea varies by region, but the source is rarely determined in less severe cases. Enterotoxigenic Escherichia coli (ETEC) is the most prevalent bacterial pathogen, accounting for approximately 30% of cases. Campylobacter jejuni, Salmonella, and Shigella spp are also prominent bacterial causes of travelers’ diarrhea. Norovirus is the most common viral infection associated with travelers’ diarrhea.
The common parasites responsible are Entamoeba histolytica, Giardia intestinalis, and Cryptosporidium. Traveler’s diarrhea can affect both temporary and long travelers, and there isn’t any immunity to future outbreaks. Traveler’s diarrhea appears to be more common in warm climates, in regions with poor sanitation, and in areas where there is an absence of refrigeration.
Furthermore, risk factors are limited clean water and using cutbacks when cooking foods. Traveler’s diarrhea is uncommon in regions where food safety education is provided.
Genetics
Prognostic Factors
The majority of people with traveler’s diarrhea have favorable results. It is self-limiting, and individuals suffer from loss of fluids and electrolytes. In cases of severe dehydration, hospitalization is required.
