Abstract
Background Analysis of a large cohort of business travelers will help clinicians focus on frequent and serious illnesses. We aimed to describe travel-related health problems in business travelers. Methods GeoSentinel Surveillance Network consists of 64 travel and tropical medicine clinics in 29 countries; descriptive analysis was performed on ill business travelers, defined as persons traveling for work, evaluated after international travel 1 January 1997 through 31 December 2014. Results Among 12 203 business travelers seen 1997-2014 (14 045 eligible diagnoses), the majority (97%) were adults aged 20-64 years; most (74%) reported from Western Europe or North America; two-thirds were male. Most (86%) were outpatients. Fewer than half (45%) reported a pre-travel healthcare encounter. Frequent regions of exposure were sub-Saharan Africa (37%), Southeast Asia (15%) and South Central Asia (14%). The most frequent diagnoses were malaria (9%), acute unspecified diarrhea (8%), viral syndrome (6%), acute bacterial diarrhea (5%) and chronic diarrhea (4%). Species was reported for 973 (90%) of 1079 patients with malaria, predominantly Plasmodium falciparum acquired in sub-Saharan Africa. Of 584 (54%) with malaria chemoprophylaxis information, 92% took none or incomplete courses. Thirteen deaths were reported, over half of which were due to malaria; others succumbed to pneumonia, typhoid fever, rabies, melioidosis and pyogenic abscess. Conclusions Diarrheal illness was a major cause of morbidity. Malaria contributed substantial morbidity and mortality, particularly among business travelers to sub-Saharan Africa. Underuse or non-use of chemoprophylaxis contributed to malaria cases. Deaths in business travelers could be reduced by improving adherence to malaria chemoprophylaxis and targeted vaccination for vaccine-preventable diseases. Pre-travel advice is indicated for business travelers and is currently under-utilized and needs improvement.

Abstract
Occupational health professionals need to know more about the health, worklife, and family life of international business travelers (IBTs). This descriptive correlational study, in two parts, examines the physiological and psychosocial experiences associated with business travel for a sample of 140 employees from western Canada's oil and gas industry. Results for Part One show that 76% of IBTs report travel related health problems, 74% have jet lag, 45% have travelers' diarrhea and gastrointestinal complaints, 12% to 16% have climate adaptation problems, and 2% report accidents and minor injuries. High risk behaviors include not carrying a first aid travel kit (54%); drinking more alcohol than ordinarily (21%); and neglecting food, water, and antimalarial precautions (6% to 14%). Other risk factors include age, length of stay, destination, pre-travel medical examinations, pre-travel advice, and eating and accommodation facilities. Findings show that IBTs are at risk for travel related physiological health problems. Implications for practitioners call for increased occupational health expertise in pre-travel preparation, follow up post-travel and regular health surveillance for employees who travel on international business.

Abstract
Background The annual number of international tourist arrivals has recently exceeded one billion, yet surprisingly few studies have characterized travelers’ behavior, illness, and risk factors in a prospective setting. Particularly scarce are surveys of data spanning travel, return, and follow-up of the same cohort. This study examines behavior and illness among travelers while abroad, after return home, and at follow-up. Patterns of behavior connected to type of travel and illness are characterized so as to identify risk factors and provide background data for pre-travel advice. Methods Volunteers to this prospective cohort study were recruited at visits to a travel clinic prior to departure. Data on the subjects’ health and behavior were collected by questionnaires before and after journeys and over a three-week follow-up. In addition, the subjects were asked to fill in health diaries while traveling. Results The final study population consisted of 460 subjects, 79 % of whom reported illness during travel or on arrival: 69 % had travelers’ diarrhea (TD), 17 % skin problems, 17 % fever, 12 % vomiting, 8 % respiratory tract infection, 4 % urinary tract infection, 2 % ear infection, 4 % gastrointestinal complaints other than TD or vomiting, and 4 % other symptoms. Of all subjects, 10 % consulted a doctor and 0.7 % were hospitalized; 18 % took antimicrobials, with TD as the most common indication (64 %). Ongoing symptoms were reported by 25 % of all travelers upon return home. During the three-week follow-up (return rate 51 %), 32 % of respondents developed new-onset symptoms, 20 % visited a doctor and 1.7 % were hospitalized. Factors predisposing to health problems were identified by multivariable analysis: certain regions (Southern Asia, South-Eastern Asia, and Eastern Africa), female gender, young age, and long travel duration. Conclusions Despite proper preventive measures like vaccinations, malaria prophylaxis, and travel advice, the majority of our subjects fell ill during or after travel. As the symptoms mostly remained mild, health care services were seldom needed. Typical traveler profiles were identified, thereby providing a tool for pre-travel advice. The finding that one third reported new-onset illness during follow-up attests to the importance of advising clients on potential post-travel health problems already during pre-travel visits.

Abstract
Purpose
– The purpose of this paper is to study well-being among the internationally mobile work force by exploring the relationships between international business traveling, work-family conflict (WFC), and health issues. In this study, these relationships are examined on the basis of the health impairment process of the job demands-resources model. More specifically, the study examines the role of WFC as a mediator between international business travel and sleep problems using a full panel design.
Design/methodology/approach
– The data for this study are drawn from Finnish employees whose work involved international business travel (n=868) and who answered two surveys with a one-year time lag.
Findings
– The results showed that international business travel in terms of the number of travel days per year, while not predicting sleep problems directly over time, did significantly increase WFC, which in turn increased sleep problems. Thus, WFC functioned as a mediator in the relationship between business travel and subsequent sleep problems.
Practical implications
– The results indicate that family-friendly HR policies and practices might help international business travelers (IBTs) reduce levels of WFC, which could in turn protect them from harmful health effects, particularly sleep problems.
Originality/value
– The study examines the understudied professional group of IBTs and contributes to the knowledge on their well-being and WFC issues.

Abstract
Illness in business travelers is associated with reduced productivity on the part of the employee as well as the employer. Immunizations offer a reliable method of preventing infectious diseases for international business travelers. The authors review the travel patterns of business travelers, available data on illnesses they encounter, their potential travel-associated risks for vaccine-preventable diseases and recommendations on immunizations for this population. Routine vaccines (e.g., measles, tetanus and influenza) should be reviewed to assure that they provide current coverage. The combined hepatitis A and hepatitis B vaccine with a rapid schedule offers options for those with time constraints. Other vaccine recommendations for business travelers need to focus on their destinations and activities and underlying health, taking into account the concept of cumulative risk for those with frequent travel, multiple trips or long stays.

Abstract
Background Respiratory tract infections frequently occur in ill returned travelers, a minority of whom present with pneumonia. The most accurate and cost-effective diagnostic work-up remains an area of uncertainty. In this retrospective cohort study, the utility of routine chest radiography was evaluated. Methods This study was performed at the Institute for Tropical Diseases in Rotterdam and included all returned travelers in the period between 2007 and 2009 that were ill with symptoms lasting less than 1 month and had chest radiography on admission. Travelers’ demographic (including travel history), clinical, and laboratory data were collected on admission and evaluated for their diagnostic power to predict radiographic evidence of a pulmonary infiltrate. Results Fifty-three (7%) of 750 ill returned travelers had radiographic evidence of a pulmonary infiltrate. Presentation with cough (odds ratio [OR] 2.80, 95% confidence interval [CI] 1.46–5.38), or elevated C-reactive protein values (OR 1.13, 95% CI 1.09–1.17), and white blood cell count (OR 1.08, 95% CI 1.05–1.17) strongly correlated with the presence of a pulmonary infiltrate. Recursive partitioning analysis identified a subset of 384 patients presenting with both cough and fever, or C-reactive protein values in excess of 23 mg/L that would optimally benefit from chest radiography. Conclusion The results of this study indicate that a more judicious use of chest radiography in the routine work-up of ill returned travelers is warranted.

Abstract
Although international business travel is increasing, there is a lack of research on its repercussions for mental health. This study analysed the long-term influence of international business travel on the mental health status by comparing depression, anxiety and job stress between workers with and without international assignment experience. The subjects were divided into an 'experienced group' composed of 70 male workers who had experienced an overseas assignment of at least six months, and a 'non-experienced group' consisting of 2,163 male workers who had not. To assess the mental health status, Zung's Self-Rating Depression Scale (SDS) and Sheehan's Patient Rated Anxiety Scale (Sheehan) were employed. The Job Content Questionnaire (JCQ) was used to examine job stress. In addition, information about the characteristics of the overseas assignments was collected. The experienced group had significantly higher scores for job control, supervisor support and co-worker support in the JCQ, while no differences were observed for the SDS and Sheehan. Whether or not the subjects travelled abroad with their families, whether or not they went against their will, and whether or not they enjoyed their stay had no effects on their mental health. Job demand had a significantly positive correlation with the duration of the assignment.

Abstract
This article describes the use of poorly absorbed antibiotics for the treatment of traveler's diarrhea. Poorly absorbed oral antibiotics can deliver high concentrations of drug to the site of enteric infection with minimal risk of systemic adverse effects, toxicity, and drug interactions. Compared with systemically absorbed oral antibiotics, poorly absorbed oral antibiotics may be less associated with the pressure that leads to the development of bacterial resistance, because they do not affect bacteria outside the gastrointestinal tract. In clinical studies, poorly absorbed oral antibiotics, including aztreonam, bicozamycin, and rifaximin, were more effective than and as well tolerated as placebo; in particular, rifaximin was as effective as oral ciprofloxacin in reducing the duration of illness in traveler's diarrhea. More research is warranted to delineate the effects of poorly absorbed antibiotics in invasive infection and to assess the potential for the development of bacterial resistance.

Abstract
BACKGROUND Even among travelers who undergo evaluation in travel medicine clinics, illnesses develop despite the emphasis placed on prevention. It is possible that travel-associated disease rates may be modified by maximizing access to care and augmenting educational methods of disease prevention. Use of alternative preventive measures such as alcohol hand gel sanitizers may also alter illnesses among travelers. METHODS We assessed medical outcomes in a travel population cared for in the setting of free vaccinations, medications, and travel medicine consultation, in which personal preventive measures were presented in numerous formats by a physician specializing in infectious diseases. An initial demographic questionnaire was administered at the time of travel consultation. A post-travel telephone interview conducted 2 weeks after return from travel evaluated illness while abroad, illness upon return, and adherence to travel recommendations. An assessment was also performed regarding the utility of an alcohol hand gel sanitizer. RESULTS One hundred fifty-five travelers were evaluated (primarily older, well-educated US-born travelers, on vacation with family or coworkers). Travelers filled their prescriptions 98% of the time; 77% reported adherence to antimalarial chemoprophylaxis. Sixty-four percent of travelers developed illness abroad, and 20% developed illness upon return. The most frequent complaints were diarrhea and upper respiratory illness. Ten percent of travelers altered their itinerary owing to illness. The use of alcohol hand gel sanitizers did not appear to impact the development of diarrhea or respiratory illnesses. CONCLUSION In this small group of travelers, access to free consultation, vaccinations, and medications along with presentation of personal protective measures in various formats did not seem to influence the development of illnesses among travelers. Although not rigorously analyzed, alcohol hand gel sanitizers did not seem to alter diarrhea or respiratory tract illness rates. These data highlight the need for new or more effective methods to prevent illness among travelers.

Abstract
BACKGROUND Traveling to tropical regions is related to increased health risks. Travelers' diarrhea is the most frequent health problem, but the range of travel-related diseases also includes potential life-threatening diseases such as malaria. The actual risk of European travelers acquiring specific infectious diseases and other hazards in the tropics is to a large extent unknown and is therefore often adopted from that of the indigenous population. The objective of this study was to elucidate the risk for travel-related diseases, symptoms, and accidents in a population of Europeans who travel to popular tourist destinations. METHODS From July 2003 to June 2004, 794 travelers consulting the travel clinic of the Berlin Institute of Tropical Medicine were recruited for a questionnaire-based observational study before traveling to Kenya, Tanzania, Senegal, the Gambia, India, Nepal, Thailand, or Brazil. RESULTS Overall, illness was reported by 42.9% of travelers, with 10.2% reporting more than one adverse health event. Most frequently gastrointestinal symptoms were noted (34.6%), followed by respiratory symptoms (13.7%). More than 5% experienced an accident. Travel to the Indian subcontinent nearly doubled the risk of becoming ill; travel to Thailand significantly decreased the risk. Additional risk factors were a long duration of staying abroad, young age, and traveling under basic conditions. Of all travelers, 80% did not follow the traditionally recommended dietary restrictions. Among travelers visiting malaria-endemic areas, 20% did not carry any antimalarial drugs with them, not continuous chemoprophylaxis or standby medication. CONCLUSIONS Because of the rising travel activity, especially to tropical countries, the importance of qualified pretravel advice consultation is increasing. To improve the travelers' health, attention needs to be paid to individual risk factors, the prevention and therapy of travelers' diarrhea, malaria prophylaxis, management of respiratory illness, and personal safety.

Abstract
BACKGROUND A review of the activities of the Grampian travel clinic was carried out over 1 year to obtain an overall perspective of the clinic workload and to determine how much of the workload was dependent on the oil industry. METHODS A specially designed data collection sheet was completed for each of the 669 consultations conducted at the Grampian travel clinic, Aberdeen, between February 1, 2002, and January 31, 2003. RESULTS Patients attending the clinic came in equal numbers from the city of Aberdeen and the Grampian region. Twenty-five percent were traveling for work purposes: 87.4% of this travel was oil related, and most patients were headed to Africa. The commonest vaccines given were for yellow fever, Japanese B encephalitis, and rabies, reflecting the specialist nature of the clinic. Most travelers did leave adequate time for immunization before travel. The public is still apprehensive about using mefloquine as malarial prophylaxis. CONCLUSIONS Most attendees were traveling on holiday, but a quarter of the consultations were for travel related to the oil industry. Almost 70% of attendees had already visited their general practitioner and were therefore attending the clinic for specialist advice and vaccines. There is a need for increased clinic capacity.

Abstract
Respiratory tract infections are common in travelers, and improving our knowledge of risk factors associated with specific types of respiratory infections should enable implementation of better preventive strategies. Data collected by the GeoSentinel surveillance network were analyzed, and the most significant predictors for developing specific categories of respiratory infections while abroad were age, sex, season of travel, trip duration, and reason for travel. In particular, influenza was associated with travel to the Northern Hemisphere during the period of December through February, travel involving visits to friends or relatives, and trip duration of >30 days. Lower respiratory tract infections were associated with male sex and increasing age. Knowledge of the respiratory tract infections that occur in specific groups of travelers allows for the development of targeted pretravel preventive strategies to high-risk groups.

Abstract
BACKGROUND Travel to hepatitis A-endemic countries is frequent among North Americans. Such travel carries significant risks for the individuals themselves and for the general population. We documented the patterns of use of travel clinics in a large Canadian adult population. METHODS Travelers who had visited a hepatitis A-endemic country between 1990 and the time of the survey in 1999 were eligible. Subjects were identified from a representative sample of 4,002 adults from the two largest Canadian provinces. They were contacted by random digit dialing and interviewed by telephone. RESULTS Only 15% of trips had been preceded by a visit to a travel clinic. The probability of visiting a travel clinic was approximately 10 times greater for travelers considered to be in the high-risk category than for those in the low-risk category, but the former represented only 2% of the total. The probability of visiting a travel clinic was approximately 23 times greater for travelers who were aware of the health risks in their country of destination. Income level was not associated with attendance at a travel clinic, and cost was rarely mentioned as a reason for not attending such a travel clinic before departure. CONCLUSIONS Each year, millions of Canadian travelers go to hepatitis A-endemic countries without consulting a travel clinic. Active steps must be taken by public health authorities to improve their utilization of health services and prevent the accrued health risk for these travelers.

Abstract
BACKGROUND The Coca-Cola travel health kit has been used for about one decade for international travelers and required evaluation to see if the items contained were appropriate for the employees. METHODS Two hundred thirty-four travelers were sampled and filled out a voluntary survey including questions about demographic information, travel history, and usage and value of the contents of the travel health kit. RESULTS One hundred eighty-one surveys were returned; 65% of the respondents were male, and the majority of travelers were between the ages of 36 and 45 years. The most useful items were analgesics and medications used for gastrointestinal problems. In general, the items identified as being the least useful were those requiring specialized use by a medical practitioner, such as needles and syringes. Suggestions of items to be added to the kit included vitamins, cough drops, sleep aids, and eye drops. A surprising result that Coca-Cola employees expressed the desire for brand name rather than generic items. CONCLUSIONS Evaluation of the Coca-Cola Company travel health kit revealed it to be very useful to most corporate travelers. Suggestions that were made will be taken into consideration in designing a new kit, and consideration is being given to whether a basic travel health kit should be provided to which travelers can add other items depending on their personal needs.

Abstract
OBJECTIVES In late 1996, a multinational investigation was launched following an outbreak of diarrheal illness that caused the disruption of an international scientific conference at a first-class hotel in Puerto Vallarta, Mexico. METHODS A questionnaire was mailed to all American and to selected international attendees. Additional copies of the questionnaire were provided for any family members who may have attended the conference. A case was defined as an illness with three or more loose stools during a 24-h period in a conference attendee or accompanying family member, with illness lasting 2 or more days and onset between 6 and 9 November 1996. RESULTS Questionnaires were returned by 81% (232/288) of American attendees, 47% (18/38) of selected international attendees, and 25 family members; 30% (83/275) of respondents met the case definition. Ill persons resided in at least seven countries. Salmonella serotype Enteritidis phage type 4 was isolated from stool specimens from patients residing in Canada, the UK, and the USA. Attending a hotel banquet on 6 November was associated with illness; 42% (82/194) of banquet attendees became ill versus 3% (1/37) of non-attendees (relative risk (RR)515.6, 95% confidence interval (CI)52.3-108.9). The only banquet food item associated with illness was chili rellenos; 53% (58/109) of persons who ate chili rellenos were ill versus 22% (12/55) of those who did not (RR52.4, 95% CI51.4-4.1). Chili rellenos ingredients included shelled eggs and cheese; Salmonella was isolated from the leftover cheese but the isolate was not serotyped. CONCLUSIONS Salmonella may be a cause of traveler's diarrhea and can result in outbreaks even among travelers who follow routine precautions (i.e. staying in a first-class hotel and eating hot foods). International collaboration in investigating similar outbreaks, including sharing subtyping results, will be necessary for long-term prevention. Global Salm-Surv, an international network of Salmonella reference laboratories coordinated by the World Health Organization, may facilitate such collaboration.

Abstract
BACKGROUND Corporations with employees who travel internationally address their travel-related medical needs in a variety of ways. Options utilized include corporate medical departments, local health departments, and local clinics, both contracted and independent. METHODS A travel clinic at a university medical center routinely provided preventive travel medicine services for many of the local companies. Two of these companies had on-site medical clinics which routinely saw patients for occupational and personal health reasons. At these companies , the university travel clinic assisted in moving employee travel medicine services to the on-site clinic. Direct and indirect costs for new, predeparture employee travel care at each company were compared before, and after, the move on-site. RESULTS When measured per patient, total cost savings associated with the on-site travel clinic were greater than 15% at both companies (17%, 25%), primarily due to the value of the employees' time saved with decreased travel. Utilization increased at one company by 24% over the first 8 months and lead to higher overall cost, but this cost increase was only 4%. Informal assessments of the value of the on-site service at both companies was uniformly positive. CONCLUSION For certain corporate settings, on-site clinics may be effective ways of providing travel medicine services.

Abstract
BACKGROUND Millions of Americans visit developing countries each year, however, little is known about their health during travel. This study describes health problems in a large cohort of American travelers during and after their trip. METHODS A 2-year survey of 784 travelers (95% follow-up) was conducted for persons traveling for < or = 90 days. At the pretravel visit, travelers were given a postcard to record adverse health events. Following travel, standardized telephone interviews were performed for any positive responses, or if the card was not returned. All travelers were contacted 2 months after return to determine late occurring illness and compliance with antimalarials. RESULTS Travelers had a mean age of 44 years, a median duration of 19 days, and visited 123 countries. An illness was reported by 64% (1.6 illnesses per traveler). Ill travelers were more often female, and traveled longer than those who were not ill; depending upon destination, each day of travel increased by 3 to 4% the chance of becoming ill. Diarrhea was most common, occurring in 46%; 34% met a strict definition for traveler's diarrhea. Respiratory illness occurred in 26%, skin disorders in 8%, acute mountain sickness in 6%, motion sickness in 5%, accidents and injuries in 5%, and isolated febrile episodes in 3%. Medical care was sought by 8% of all travelers and 12% of those reporting illness. On return, 26% of travelers were ill, 56% of whom became ill after return. Diarrhea, respiratory illness, skin disorders, and febrile syndromes were most common, and 46% of those who were ill sought medical care. Complete compliance with antimalarials was 80%. Noncompliant individuals usually discontinued medications on return. Side effects were reported by 4% of those taking chloroquine, 11% of those taking chloroquine plus proguanil, and 14% of those taking mefloquine, with half of these neuropsychiatric. The incidence of documented malaria was 3.8 cases per 1,000 travelers. CONCLUSIONS Many travelers experience adverse health events during and after travel to the developing world. Attention to the prevention and therapy of traveler's diarrhea, prophylaxis of malaria, management of respiratory illness, personal safety, and access to medical care during travel, and, recognition of clinical syndromes after return, will help to improve the traveler's health.
