Because symptoms may not start until several days after exposure, it may be difficult to pinpoint exactly what made you sick. While recovering, be particularly careful to avoid any contaminated food or water sources. This will speed up healing and prevent continued or repeat exposure. Try to drink bottled water.
Wash your hands often, especially before eating and touching your face. Keep children from putting anything, including their hands, into their mouth.

Learn about foods that cause diarrhea…. Enteroaggregative and other E. There is increasing discussion of Aeromonas spp. Viral diarrhea can be caused by a number of pathogens, including norovirus, rotavirus, and astrovirus.
Giardia is the main protozoal pathogen found in TD. Entamoeba histolytica is a relatively uncommon cause of TD, and Cryptosporidium is also relatively uncommon. The risk for Cyclospora is highly geographic and seasonal: the most well-known risks are in Nepal, Peru, Haiti, and Guatemala. Dientamoeba fragilis is a flagellate occasionally associated with diarrhea in travelers. Most of the individual pathogens are discussed in their own sections in Chapter 4 , and diarrhea in returned travelers is discussed in Chapter TD occurs equally in male and female travelers and is more common in young adult travelers than in older travelers.
A cohort of expatriates residing in Kathmandu, Nepal, experienced an average of 3. In more temperate regions, there may be seasonal variations in diarrhea risk. In south Asia, for example, much higher TD attack rates are reported during the hot months preceding the monsoon.
In environments in warmer climates where large numbers of people do not have access to plumbing or latrines, the amount of stool contamination in the environment will be higher and more accessible to flies.
Inadequate electrical capacity may lead to frequent blackouts or poorly functioning refrigeration, which can result in unsafe food storage and an increased risk for disease. Lack of safe water may lead to contaminated foods and drinks prepared with such water; inadequate water supply may lead to shortcuts in cleaning hands, surfaces, utensils, and foods such as fruits and vegetables.
In addition, handwashing may not be a social norm and could be an extra expense; thus there may be no handwashing stations in food preparation areas. In destinations in which effective food handling courses have been provided, the risk for TD has been demonstrated to decrease. However, even in developed countries, pathogens such as Shigella sonnei have caused TD linked to handling and preparation of food in restaurants.
Bacterial and viral TD presents with the sudden onset of bothersome symptoms that can range from mild cramps and urgent loose stools to severe abdominal pain, fever, vomiting, and bloody diarrhea, although with norovirus vomiting may be more prominent.
Protozoal diarrhea, such as that caused by Giardia intestinalis or E. The incubation period between exposure and clinical presentation can be a clue to the etiology:. Untreated bacterial diarrhea usually lasts 3—7 days. Viral diarrhea generally lasts 2—3 days. Protozoal diarrhea can persist for weeks to months without treatment.
An acute bout of gastroenteritis can lead to persistent gastrointestinal symptoms, even in the absence of continued infection see Chapter 11, Persistent Diarrhea in Returned Travelers. This presentation is commonly referred to as postinfectious irritable bowel syndrome. For travelers to high-risk areas, several approaches may be recommended that can reduce, but never completely eliminate, the risk for TD.
These include following instructions regarding food and beverage selection, using agents other than antimicrobial drugs for prophylaxis, using prophylactic antibiotics, and carefully washing hands with soap where available. Care in selecting food and beverages can minimize the risk for acquiring TD. Although food and water precautions continue to be recommended, travelers may not always be able to adhere to the advice.
The primary agent studied for prevention of TD, other than antimicrobial drugs, is bismuth subsalicylate BSS , which is the active ingredient in adult formulations of Pepto-Bismol and Kaopectate. Studies from Mexico have shown that this agent taken daily as either 2 oz. BSS commonly causes blackening of the tongue and stool and may cause nausea, constipation, and rarely tinnitus.
Travelers with aspirin allergy, renal insufficiency, and gout, and those taking anticoagulants, probenecid, or methotrexate should not take BSS.
In travelers taking aspirin or salicylates for other reasons, the use of BSS may result in salicylate toxicity. The use of probiotics, such as Lactobacillus GG and Saccharomyces boulardii , has been studied in the prevention of TD in small numbers of people.
Results are inconclusive, partially because standardized preparations of these bacteria are not reliably available. Studies are ongoing with prebiotics to prevent TD, but data are insufficient to recommend their use.
There have been anecdotal reports of beneficial outcomes after using bovine colostrum as a daily prophylaxis agent for TD. However, commercially sold preparations of bovine colostrum are marketed as dietary supplements that are not Food and Drug Administration FDA approved for medical indications. Although prophylactic antibiotics can prevent some TD, the emergence of antimicrobial resistance has made the decision of how and when to use antibiotic prophylaxis for TD difficult.
The prophylactic antibiotic of choice has changed over the past few decades as resistance patterns have evolved. Fluoroquinolones have been the most effective antibiotics for the prophylaxis and treatment of bacterial TD pathogens, but increasing resistance to these agents among Campylobacter and Shigella species globally limits their potential use.
In addition fluoroquinolones are associated with tendinitis and an increased risk of Clostridioides difficile infection, and current guidelines discourage their use for prophylaxis. At this time, prophylactic antibiotics should not be recommended for most travelers. The risks associated with the use of prophylactic antibiotics should be weighed against the benefit of using prompt, early self-treatment with antibiotics when moderate to severe TD occurs, shortening the duration of illness to 6—24 hours in most cases.
List of Partners vendors. Travelers' diarrhea TD can turn a trip into a nightmare; luckily, treatment options are available. Here is an overview of the symptoms of travelers' diarrhea, with an in-depth discussion of available treatment options, so that you can know what you need to do to take care of yourself. Travelers' diarrhea is generally caused by pathogens found in food and water.
Bacteria is the most likely culprit, along with viruses and parasites. Your greatest defense against travelers' diarrhea is prevention, so be sure to observe strict adherence to food and drink safety practices. Symptoms of travelers' diarrhea usually show up several days into your trip, although in some cases it may take two weeks for the disease to manifest itself. Symptoms will vary depending on the nature of the causative microorganism. Here are the more common symptoms of travelers' diarrhea:.
More severe cases of travelers' diarrhea may involve fever and blood in the stool. See a doctor if your symptoms are accompanied by fever or bloody stools, or last longer than 48 hours. Most cases of travelers' diarrhea last from one to five days, however, symptoms may linger for several weeks.
Getting sick while far from home is more than just inconvenient; the sudden onset and severity of symptoms can be frightening. At times like this, information is essential. Here are the main treatment options for travelers' diarrhea. Your first line of defense is hydration. For mild cases of travelers' diarrhea, any safe fluids will do, such as boiled water, broth, or prepackaged non-citrus fruit juice. Sports drinks like Gatorade are good, too, but for severe dehydration, an oral rehydration solution is the preferred option.
You can obtain oral rehydration products at most drugstores—just be sure to mix them with safe, clean water. For children, Pedialyte is a good option. Antibiotics may be used for travelers' diarrhea that is likely to have a bacterial cause, and they are reserved for only the most severe cases.
A stool test should be done to identify which antibiotic might work best. Quinolone antibiotics are often the ones given, especially Cipro ciprofloxacin. A dose of milligrams mg twice daily for one or two days may be prescribed. Quinolones are not approved for use in children or people who are pregnant. Emerging resistance to quinolones, especially in Southeast Asia where quinolone-resistant Campylobacter jejuni is a common cause of travelers' diarrhea, is a concern.
Azithromycin might be given in this case, although some strains are resistant to it as well.
