In 2011, approximately 980 million people traveled internationally.1 More than 522 million people from developed countries traveled overseas; an estimated 50 million to 100 million people traveled to developing countries.1-4 In 2007, the U.S. Department of Commerce estimated that at least 30 million Americans traveled to developing regions.4 Approximately 8% of travelers to the developing world require medical care during or after travel, and more than a quarter of those who seek medical…

Traveler's Diarrhea Recommendations for Solid Organ Transplant Recipients and Donors.

A more functional classification of traveler’s diarrhea has been proposed, taking into account the tolerability of the diarrheal illness and functional impairment of the patient that it causes.

An update on travelers’ diarrhea

Travelers’ diarrhea will continue to challenge patients and physicians despite the use of sanitation advice, prophylactic vaccines, and treatment with antibiotics, and future research should focus on novel strategies for reducing exposure to pathogens, vaccine development, early detection, and targeted treatments.

Norovirus: new developments and implications for travelers’ diarrhea

It is likely that norovirus prevalence rates are highly underestimated in travelers’ diarrhea due to rapid onset, short duration of the illness, limited availability of laboratory facilities, and the fact that most clinical laboratories lack the diagnostic capability to detect noroviruses in stool.

Review: chronic and persistent diarrhea with a focus in the returning traveler

Persistent/Chronic diarrhea is a leading syndromic diagnosis in returning travelers across all regions and lower published rates of chronic diarrhea from Sub-Saharan Africa relative to [North Africa, South Central Asia, and Central America] are identified.

Outbreak of Cyclosporiasis in Korean Travelers Returning from Nepal

Stool samples from 18 Korean residents who traveled to Nepal were obtained and examined for 25 enteropathogens including 16 bacterial species, 5 viral species, and 4 protozoans in stool samples as causative agents of water-borne and food-borne disease, but only C. cayetanensis was detected by nested PCR, and 3 PCR-positive samples were sequenced to confirm species identification.

Infectious Risks of Traveling Abroad.

Empiric treatment is sometimes necessary when suspicion of a certain diagnosis is strong and confirmatory tests are delayed or lacking, particularly for infections that are rapidly progressive (for example, malaria) or for which timing of testing is prolonged (such as leptospirosis).

Advising the traveller

Vaccine-Preventable Diseases : Routine Vaccines

The pretravel medical consultation includes immunizations, malaria chemoprophylaxis, self-treatment for traveler’s diarrhea, and advice on the prevention of a myriad of other infectious causes including dengue, chikungunya, rickettsiosis, leptospirosis, schistosomiasis, and strongyloidiasis.

A 12-Year Retrospective Study of Invasive Amoebiasis in Western Sydney: Evidence of Local Acquisition

Rec retrospective case series analysis of patients with laboratory-confirmed amoebiasis from Western Sydney Local Health District, Australia, between years 2005 and 2016 finds local acquisition of amoEBiasis occurs in Western Sydney and contributes to significant morbidity and hospital admissions.



Spectrum of disease and relation to place of exposure among ill returned travelers.

When patients present to specialized clinics after travel to the developing world, travel destinations are associated with the probability of the diagnosis of certain diseases, and diagnostic approaches and empiric therapies can be guided by these destination-specific differences.

Illnesses in travelers returning from the tropics: a prospective study of 622 patients.

Immigrants are the travelers most at risk of common tropical diseases, with the noteworthy exceptions of dengue fever and invasive schistosomiasis.

How To Hit the Runs for Fifty Million Travelers at Risk

Rifaximin is suggested to be a candidate agent for widespread prophylaxis of travelers at risk because of its minimal impact on the intestinal microflora, the absence of systemic side effects in DuPont and colleagues' trial, and the limited use of this class of drugs other than for mycobacterial infections.

Characteristics of schistosomiasis in travelers reported to the GeoSentinel Surveillance Network 1997-2008.

Screening for schistosomiasis should be encouraged for all potentially exposed travelers and especially for missionaries, volunteers, and expatriates.

Global etiology of travelers' diarrhea: systematic review from 1973 to the present.

The regional differences in pathogen identification identified will serve as a baseline for antimicrobial therapy recommendations and vaccines strategies and help to understand the drivers of travelers' diarrhea.

Global health surveillance and travelers' health

Global surveillance of travel-related disease represents a powerful tool for the detection of infectious diseases and should encourage clinicians to take a detailed travel history during every patient encounter.

The nonabsorbed rifamycin drug, rifaximin, appears to be ideally suited to become the important new drug in prevention and treatment of travelers’ diarrhea.

Bacterial enteropathogens are of the greatest importance for children living in the developing world, but this article concentrates on bacterial diarrhea in the United States, which is similar to that in other industrialized regions.

Giardia intestinalis: new insights on an old pathogen

Recent molecular evidence suggests that G. intestinalis may display a certain degree of host specificity, reigniting historical debates about the zoonotic potential of this parasite.
