Background: Diarrhoea is a common medical problem affecting travellers to Asia, Africa and Latin America. The use of prophylactic antimicrobial agents may increase the risk of contracting resistant bacteria. Findings indicate that oligosaccharides, i.e. carbohydrate chains of 3-10 monosaccharides, reduce the risk of diarrhoea. Methods: We performed a placebo-controlled, double-blind study of a galacto-oligosaccharide, B-GOS (Bimuno®, Clasado Ltd, Milton Keynes UK), vs placebo for participants travelling to countries with a high/intermediate risk of diarrhoea for 7-15 days...

Background: Travellers' diarrhoea is the most common health problem in travellers. Depending on the region visited, up to 40% of travellers develop diarrhoea during a 2-week trip. The aim of this study was to assess risk factors for TD among travellers to the Indian subcontinent. Methods: An observational prospective multicentre cohort study investigated travellers to the Indian subcontinent. Participants completed questionnaires assessing the incidence of travellers' diarrhoea and identifying potential risk factors...

Background: Gap year travellers can potentially be exposed to many infectious diseases and other travel-related health problems including injuries and psychological problems. Currently, there is little information on health and wellbeing of this particular group of travellers. Methods: Participants were recruited from an organization that specialized in organising international gap year placements. Gap year travellers were asked to complete a pre-departure survey on demographics, placement destination and duration, previous travel experience, hobbies, risk taking behaviour, anticipated problems during the placement, and pre-travel preparations...

Introduction: As international travel increases, travellers may be at increased risk of acquiring infectious diseases not endemic in their home countries. Many journal articles and reference books related to travel medicine cite that between 22-64% of international travellers become ill during or after travel; however, this information is minimal, outdated and limited by poor generalizability. We aim to provide a current and more accurate estimate of the proportion of international travellers who acquire a travel-related illness...

Background: Understanding and detecting imported diseases is a priority in the prevention and management of prevalent and emergent infectious diseases acquired abroad. The +Redivi network measures the burden of imported infections in Spain and is essential for closing the gap in travel medicine. Methods: Demographic characteristics, travel information, syndromes and confirmed travel-related diagnoses were registered in a standardised online database. Results: A total of 10 767 cases of imported infectious diseases were registered between October 2009 and December 2015...

Background: The recommendation that antibiotics should be used for routine therapy of travellers' diarrhoea is being reconsidered in view of growing evidence that the therapy may lead to intestinal carriage of multi-drug resistant (MDR) colonic microbiota. This review attempts to put the issues of therapy and MDR acquisition in perspective to help in the establishment of therapeutic recommendations for travellers' diarrhoea. Methods: The existing literature showing the risk and consequences of acquisition of MDR microbiota in antibiotic-treated travellers was reviewed...

BACKGROUND: Cholera outbreaks are recurrent in Cameroon and despite the efforts put together during epidemics, they are always associated with a high case fatality. Inadequate demand for health care is one of the major factors that might be responsible for the high case fatality. This study was conducted to describe the health seeking behaviour of suspected cases of cholera in four health districts of the Far North Cameroon. METHODS: We conducted a health facility based descriptive study involving suspected cases of cholera received in health facilities...

BACKGROUND: Limited prospective data are available on the acquisition of viral, bacterial and parasitic diarrhoeagenic agents by healthy individuals during travel. METHODS: To determine the frequency of travel associated acquisition of 19 pathogens in 98 intercontinental travellers, qPCR was used to detect 8 viral pathogens, 6 bacterial enteric pathogens and 5 parasite species in faecal samples collected immediately before and after travel. RESULTS: We found high pre-travel carriage rates of Blastocystis spp...

Incidence of hepatitis A in Wales is low (average of 0.48/100,000 inhabitants from 2004-2015). We describe a community outbreak of hepatitis A involving 3 schools (primary and secondary) in South Wales between March and June 2016 and reflect on the adequacy of the control measures used. Anyone in South Wales epidemiologically linked to a serological and/or RNA positive confirmed case of hepatitis A during the 15-50 days before onset of symptoms (diarrhoea, vomiting, fever, nausea, AND jaundice, or jaundice-associated symptom) was defined as a case...

Intestinal coccidian parasites are intracellular protozoa most frequently transmitted during food-borne and water-borne infections. This group of parasites is responsible for acute diarrhoeal illnesses especially among immunocompromised patients. However, they are more frequently detected in immunocompetent individuals including travellers, and they should also be considered as important etiologic factors of travellers' diarrhoea. We examined 221 immunocompetent patients hospitalized due to acute or chronic diarrhoea and other gastrointestinal symptoms after returning from international journeys to hot climates...

Antimicrobial resistance is a global problem which affects also tropical countries. Travelers to these regions expose themselves to the risk of being colonised and infected with multidrug-resistant bacteria. The region visited, the occurrence of diarrhoea and the use of antibiotics are the principal risk factors leading to colonisation with multidrug-resistant Enterobacteriaceae, which can affect up to 80% of travellers. Colonisation with meticillin resistant Staphylococcus aureus and vancomycin resistant enterococci are often due to contacts with the health care system of the visited country...

BACKGROUND: Giardia intestinalis is microaerophillic diarrhoea-causing protozoan common in countries with suboptimal sanitation. Standard treatment is with nitroimidazoles but a growing number of refractory cases are being reported. Treatment failure has become increasingly prevalent in travellers who contract giardiasis in Asia. Clinicians are increasingly falling back on second line and less well known drugs to treat giardiasis. AIMS: To review nitroimidazole-refractory G...

Background: Travellers' diarrhoea affects tens of millions of people travelling to less developed countries or regions annually. There are positive reports of the use of rifaximin, a non-absorbed, gut-selective antibiotic to prevent travellers' diarrhoea. This study will critically review and analyse clinical trials on the subject. Methods: Using the keywords [diarrhoea OR diarrhoea OR travel*] AND [rifaximin OR xifaxan OR xifaxanta OR normix OR rifagut], a preliminary search on the PubMed and Ovid databases yielded 411 papers published in English between 1 January 1988 and 1 July 2016...

Background: The number of Thai tourists visiting India is increasing each year. Most studies investigating health problems among international travellers to India have focused on travellers from Europe or North America, and the applicability of these studies to Asian travellers is unknown. Methods: This cross-sectional study used data collected from Thai tourists who had recently completed a trip to India. A questionnaire on demographic data, travel characteristics, pre-travel health preparation, and health problems during the trip to India was administered...

Background.: Travellers' diarrhoea (TD) is a common problem, affecting millions of tourists each year and creating a large economic burden. Risk factors for TD are known and guidelines exist to assist practitioners in advising travellers on how to prevent and treat TD. However, data are lacking regarding actual prescribing practices or approaches used in TD management. This study aims to establish a baseline which identifies uniformities and diversities in practice. Methods...

Background: There is increasing recognition of the contribution of community-acquired cases to the global burden of Clostridium difficile infection (CDI). The epidemiology of CDI among international travellers is poorly understood, and factors associated with international travel, such as antibiotic use and changes in gut microbiota, could potentially put travellers at higher risk. Methods: We summarized demographic, travel-associated and geographic characteristics of travellers with CDI in the GeoSentinel database from 1997 to 2015...

INTRODUCTION: Amoebiasis is the third most frequent cause of mortality after malaria and schistosomiasis. In developed countries, amebiasis is also seen in migrants who have travelled to endemic areas. The factors responsible for its progression from intestinal amebiasis to an amebic liver abscess are not fully understood. CASE PRESENTATION: A 54-year-old man presented with abdominal pain, fever and diarrhoea. Laparotomy confirmed an inflammatory mass involving the right colon, and he underwent a right hemicolectomy...

OBJECTIVE: The aim was to analyse those syndromes without fever in travellers who return from tropical regions evaluated at our Department of Infectology and Tropical Medicine. Clarifying these conditions intends to reach earlier diagnoses and, perhaps, to avoid the emergence and spread of imported diseases, as well as to establish appropriate preventive measures. METHODS: An observational descriptive transversal study was performed, selecting those patients who returned from tropical regions without fever (n = 281), amongst all travellers evaluated in our department between 1998 and 2013...

BACKGROUND: One third of travellers to the poor regions of the (sub)tropics become colonized by extended-spectrum beta-lactamase-producing Enterobacteriaceae (ESBL-PE). Co-resistance to non-beta-lactam antibiotics complicates the treatment of potential ESBL-PE infections. METHODS: We analysed co-resistance to non-beta-lactams among travel-acquired ESBL-PE isolates of 90 visitors to the (sub)tropics with respect to major risk factors of colonization: destination, age, travellers' diarrhoea (TD) and antibiotic (AB) use...

BACKGROUND: Visceral leishmaniasis (VL) is a protozoan disease, which is responsible for 200.000-400.000 yearly infections worldwide. If left untreated, the fatality rate can be as high as 100% within 2 years. 90% of cases occur in just six countries: India, Bangladesh, Sudan, South Sudan, Ethiopia and Brazil. It is thus a disease rarely seen by physicians in Europe or North America. We report on the fatal case of VL in an 80-year-old immunosuppressed patient who presented with a latency of over 15 years after having visited an endemic region...
