Travel characteristics and health practices among travellers at the travellers' health and vaccination clinic in Singapore.

INTRODUCTION: Singapore has a fast-growing travel industry, but few studies have been done on travel characteristics and travel health practices. This study describes the profile and healthseeking behaviour of travellers attending a travel health clinic in Singapore. MATERIALS AND METHODS: A cross-sectional survey was conducted on travellers attending the Traveller's Health and Vaccination Centre (THVC) between September and November 2002 using a standardised questionnaire. Information obtained included individual demographic and medical information, travel patterns, vaccination status and travel health practices. RESULTS: Four hundred and ninetyfive (74%) eligible travellers seen at THVC responded to the questionnaire. Their mean age was 36 years; 77% were professionals, managers, executives, and businessmen, students, and white collar workers. Asia was the main travel destination, and most travelled for leisure and resided in hotels or hostels. The median duration of travel was 16 days. Although >90% had previously travelled overseas, only 20% had previously sought pre-travel advice. Malays were significantly underrepresented (P < 0.01); and Caucasians and Eurasians were significantly more likely (P < 0.01) to have previously sought pre-travel advice compared with Chinese, Indians and Malays. Factors associated with seeking pre-travel advice included travel outside of Asia, especially Africa and South America. CONCLUSION: Singaporean travellers travel more often to cities rather than rural areas, compared with non-Asian travellers. Asia is the preferred destination, and travel outside of Asia is perceived as more risky and is associated with seeking pre-travel advice and vaccinations. Travel patterns and behaviours need to be taken into account when developing evidence-based travel medicine in Asia.

Increasing referral of at-risk travelers to travel health clinics: evaluation of a health promotion intervention targeted to travel agents.

BACKGROUND: Increases in travel-related illness require new partnerships to ensure travelers are prepared for health risks abroad. The travel agent is one such partner and efforts to encourage travel agents to refer at-risk travelers to travel health clinics may help in reducing travel-attributable morbidity. METHODS: A health promotion intervention encouraging travel agents to refer at-risk travelers to travel health clinics was evaluated. Information on the knowledge, attitudes, and behaviors of travel agents before and after the intervention was compared using two self-administered questionnaires. The Wilcoxon signed rank test was used to compare the mean difference in overall scores to evaluate the overall impact of the intervention and also subscores for each of the behavioral construct groupings (attitudes, barriers, intent, and subjective norms). Multiple regression techniques were used to evaluate which travel agent characteristics were independently associated with a stronger effect of the intervention. RESULTS: A small improvement in travel agents overall attitudes and beliefs (p =.03) was found, in particular their intention to refer (p =.01). Sixty-five percent of travel agents self-reported an increase in referral behavior; owners or managers of the agency were significantly more likely to do so than other travel agents (OR = 7.25; 95% CI: 1.64 32.06). Older travel agents, those that worked longer hours and those with some past referral experience, had significantly higher post-intervention scores. CONCLUSIONS: Travel agents can be willing partners in referral, and agencies should be encouraged to develop specific referral policies. Future research may be directed toward investigating the role of health education in certification curricula, the effectiveness of different types of health promotion interventions, including Internet-facilitated interventions, and the direct impact that such interventions would have on travelers attending travel health clinics.

High-risk travel abroad overtook low-risk travel from 1999 to 2004: characterization and trends in 2,622 Spanish travelers.

BACKGROUND: Travel medicine in Spain is provided by a few specialized centers that do not come under the auspices of the main health system. Some kind of reform is required to avoid common summer collapses and postponements of the service. In contrast to other European countries, neither the exact role nor the responsibilities of general practitioners and primary health care in travel medicine are clearly defined. METHODS: An observational study was performed with retrospective data concerning 2,622 travelers from 1999 to 2004. Although the study was performed at a third-level travel medicine center, continuous contact with and support to general practitioners was maintained throughout the period. RESULTS: International travel was a steadily increasing reality between 1999 and 2004 despite well-known tragic events involving world safety. The number of high-risk travels (53.4%) also increased and even overtook low-risk ones (46.6%). This trend was explained as the result of an increasing number of journeys to sub-Saharan Africa (14.9%) and those made by traveling immigrants (64.1% of those journeys), which represented a significantly higher proportion of high-risk travels compared with those made by autochthonous subjects (52.1%; p < .001). Moreover, traveling immigrants tend to consult more frequently in periods < 15 days prior to travel than do autochthonous travelers (p < .0001). A substantial number of highly vulnerable travelers, such as pregnant women, infants, elderly people, and immunosuppressed subjects, was found (1.8%). Low-risk travelers who could have been advised and vaccinated by general practitioners were 1,139 (43.4%). CONCLUSIONS: Given the increasing number of travelers undertaking high-risk travels abroad, any kind of reinforcement of travel medicine provision in Spain should be considered essential. General practitioners could attend to a significant proportion of low-risk travelers.

Mefloquine for preventing malaria in non-immune adult travellers.

OBJECTIVES: Mefloquine has now largely replaced earlier malaria prophylaxis drugs which are no longer considered to be effective against all Plasmodium species, due to parasite resistance. However mefloquine may be associated with neuropsychological harmful effects. The objective of this review was to assess the effects of mefloquine in adult travellers. SEARCH STRATEGY: We searched the Cochrane Infectious Diseases Group trials register, Medline, Embase, Lilacs, Science Citation Index and reference lists of articles. We contacted researchers in the subject of malaria chemoprophylaxis, and drug companies. SELECTION CRITERIA: Randomised trials comparing mefloquine with other standard prophylaxis or placebo in non-immune adult travellers. DATA COLLECTION AND ANALYSIS: The two reviewers independently assessed trial quality and extracted data. Study authors were also contacted. MAIN RESULTS: Ten trials involving 2750 non-immune adult travellers were included. One trial comparing mefloquine with placebo showed mefloquine prevented malaria episodes in an area of drug resistance (odds ratio 0.04, 95% confidence interval 0.02 to 0.08). Withdrawals in the mefloquine group were consistently higher in four placebo controlled trials (odds ratio 3. 56, 95% confidence interval 1.67 to 7.60). In five trials comparing mefloquine with other chemoprophylaxis, no difference in tolerability was detected. REVIEWER'S CONCLUSIONS: Mefloquine prevents malaria, but there is not enough evidence to evaluate its tolerability and toxicity, particularly for general travellers.

Travel Illness and the Family Practitioner: A Retrospective Assessment of Travel-Induced Illness in General Practice and the Effect of a Travel Illness Clinic.

As the recognition of the discipline of Travel Medicine grows with increased international travel, an examination of both the value of pretravel advice as well as the general practitioner's role in preparation for, care during, and diagnosis and treatment after travel is necessary. This study was conducted to determine the incidence of travel-related illness in a typical urban population in Scotland and to examine the efficacy of our pretravel clinic related to reduction of illness, preparedness of our patients for travel, and the effects of our travel clinic on the workload generated by the returning ill in our practice. In this retrospective study, 1568 patients, presenting within a 1-year period from 1992-1993 at a medical practice and 100 patients at a travel clinic were studied. Their morbidity rates and, therefore, the effect of the travel clinic on prophylaxis and pretravel advice were determined. In the practice sample, 42% of travelers became ill while abroad, with 48% of ill travelers returning to consult their family doctor at home. Travelers to Africa and Asia were shown to have the highest rates of illness. Travel clinic attendees were more likely to be traveling to high-risk destinations, but were better prepared, experiencing a significantly lower rate of illness during travel (22%). Clinic attendees were less likely to consult their doctor on return home, preferring instead to resolve their illness by self-medication. The results suggest that travel clinics significantly reduce the morbidity of illness for travelers and that the burden on general practices could be reduced with the pretravel advice and prophylaxis that travel clinics can provide.

Pre-travel health, immunization status, and demographics of travel to the developing world for individuals visiting a travel medicine service.

It is estimated that five million Americans will travel to the developing world over the next year. This study examines the demographic profile, past medical and immunization history, itinerary, and reason for travel of 2, 445 travelers to the developing world seen at a travel medicine service from 1984 through 1989. The travelers age ranged from three months to 85 years (mean age 43). A chronic medical condition was reported by 654 (27%). Four percent of all travelers were intolerant of sulfonamides, and 9% had contraindications to mefloquine for malaria prophylaxis. Many travelers were due to receive the primary series or updatings of routinely recommended immunizations: 43% for tetanus/diphtheria, 55% of those born after 1956 for measles, and 70% for polio if their travel itinerary included a polio risk. Most travel (71%) was for vacations, 13% was for teaching or study, 11% for business, and 5% for missionary activities. The median duration of travel was 21 days; 5% traveled for more than one year. While over 150 countries were visited, 52% of all travel was to 10 countries in East Africa, the Indian subcontinent, the Far East, and South America. Information about the epidemiology of travel to the developing world can help physicians and travel medicine services develop more effective preventive measures for travelers.

[Self-medication of 193 travelers in the tropics. Recommendations for clinical counseling of tropical travelers and organization of a tropical travel pharmacy].

Medical advice for the traveller is of increasing importance since in the past decade in industrialized countries there is a steady increase in numbers of travellers and distance travelled. Self medication was evaluated in 193 travellers to malaria-endemic areas. Diarrhoea, fever and headache were the most frequent symptoms. Antidiarrhoeal agents, analgetics/antipyretics, antibiotics and oral contraceptives were the drugs most often used by travellers. One case of mefloquine-resistant and chloroquine-sensitive Plasmodium falciparum malaria acquired in West Africa was reported, another patient took pyrimethamine/sulfadoxine because of suspected malarial fever. The main reasons for drug consumption in travellers to tropical and subtropical areas are functionally divided into 4 groups: vaccination and prophylaxis, medication during the outward and return journey, illness occurring during stay abroad and long-term medication. This classification should be considered when medical advice is given for travellers and is the basis for choosing the contents of a pocket dispensary for travellers.

The impact of travel acquired illness on the world traveller and family doctor and the need for pre-travel health education.

This retrospective study involved a 20% quota, age and sex stratified sample of people over 16 years of age, presenting to a group medical practice over a period of one year (N = 1568). A standardised, computer-scored, self-report questionnaire was administered. The response rate was 98.3%. 42% of respondents had travelled outwith the UK in the previous year. Of those, 42% had become ill whilst abroad. In 20.5% of cases the illness settled without treatment. However, 26% of the patients required consultation with a doctor whilst abroad and 48.4% of those becoming ill required further attention from the family doctor on return home. 5% of ill travellers were admitted to hospital abroad. 8% of all travellers did not have medical insurance cover. A large and significant population of travellers become ill whilst abroad, and travel-acquired illness has a large impact on general practice, with 1 in 5 travellers seeking GP consultation on return home. Improved practice-generated pre-travel health advice might decrease this burden on primary care.

The pre-travel medical evaluation: the traveler with chronic illness and the geriatric traveler.

The pre-travel medical evaluation of elderly patients and patients with chronic illness requires special assessment and advice. Screening and special precautions are reviewed for traveling patients with respiratory disease, cardiac disease, sinusitis, diabetes mellitus, HIV infection, and other chronic medical conditions. Current guidelines for empiric therapy and prophylaxis of travelers' diarrhea are reviewed, with emphasis on concerns in geriatric or chronically ill travelers. Special considerations such as potential drug-drug interactions and insurance coverage are also discussed.

Travel health information at commercial travel websites.

BACKGROUND: Internet travel purchases accounted for 10% of the travel industry revenue generated in 2001. To ensure that travelers remain healthy during excursions to developing countries, travel health information needs to be available at commercial travel websites. We evaluated the current availability of travel health information at these websites. METHODS: The existence, adequacy and ease of access of the travel health information provided on commercial travel websites was assessed through a review of the top 25 airline and 20 discount travel websites. Each site was examined to determine whether it provided general information, such as jet lag, or international travel health information, such as malaria prophylaxis. We also assessed hyperlinks to external travel health information websites, such as the CDC, when provided. RESULTS: Travel health information was not available at 20 (44%) commercial travel websites, including 36% of airline and 55% of the discount travel websites. Twenty-eight percent of airline websites contained general information only, 8% links only, and 28% general and international information. Travel health information available at discount travel websites included 10% general only, 30% link only, and 5% general and international information. On average, it took three clicks to access travel health information. Keywords clicked to access travel health information frequently did not obviously refer to health. Each of the six travel health website links provided accurate vaccine and travel health information. However, several links lacked disease-specific maps and details of disease risk (i.e. seasonal and regional variations of malaria risk). CONCLUSIONS: Travel health information on commercial travel websites may be the only data available to travelers purchasing online. The information currently provided is generally inadequate. Ideally, commercial travel websites would provide uniform information that is accurate and easily accessible. Internationally recognized organizations should consider establishing guidelines for the information provided on commercial travel websites.

Travel health: perceptions and practices of travel consultants.

BACKGROUND: The global increase in international travel puts travelers at risk of travel-related morbidity and mortality. Prior to travel, most travelers have contact with a travel agency, thereby providing an opportunity for intervention. With this in mind we aimed to determine some of the travel-related health knowledge, practices and needs of travel consultants. METHODS: A cross sectional study was undertaken in which one travel consultant from each of 166 Western Australian travel agencies was asked to complete a self-administered questionnaire. RESULTS: One hundred and forty-five travel agencies (87%) agreed to participate in the study. Fifty-six percent indicated that they "usually" gave broad travel-related health guidelines and recommended their clients consult a medical practitioner. Almost all travel consultants reported discussing travel health insurance; very few provided information on sexually transmissible diseases, the risks associated with drug use, or first aid kits. Over 80% responded correctly to statements eliciting their knowledge on yellow fever, malaria, and food safety; the majority incorrectly answered questions on dengue fever and altitude sickness. Fifty-six percent of respondents thought that there was "not enough" readily accessible travel health information; 52% said they would like to be more involved in providing health information to their clients. CONCLUSIONS: Contact between travelers and travel agents offers an opportunity to promote awareness of travel-related health hazards. While travel consultants' health knowledge on some topics is adequate, in other areas it is inconsistent. Many travel consultants in Western Australia expressed a willingness to be involved in future health promotion activities. This participation may be best nurtured by providing travel consultants with: (1) better health education so they are able to identify high-risk travelers and destinations for medical referral; and, (2) health information in a format they feel comfortable distributing to their clients.

The 2001 National Household Travel Survey: a look into the travel patterns of older Americans.

INTRODUCTION: The main objective of this paper is to highlight travel patterns of older adults living in the United States as depicted in the 2001 National Household Travel Survey (NHTS). The NHTS is a national data collection program sponsored by the Bureau of Transportation Statistics and the Federal Highway Administration. It is the first national comprehensive household survey of both daily and long-distance travel, allowing for analysis of the full continuum of personal travel by Americans. To better understand the transportation needs of older Americans, it is useful to examine how travel patterns differ across age groups. The intent is to present basic travel characteristics of older adults (age 65+) and allow for comparisons with younger adults (ages 19-64). Travel-related characteristics of older adults in the United States: Results of the 2001 survey showed that older Americans travel extensively and rely on personal vehicles as heavily as their younger counterparts. Older Americans conduct 89% of their travel in personal vehicles. CHARACTERISTICS OF DAILY TRIPS TAKEN BY OLDER ADULTS: Older adults tend to be less mobile in that they take fewer trips, travel shorter distances, and have shorter travel times. This pattern is even more pronounced among older women. They are also more likely to suffer from self-reported medical conditions that further limit their travel. Characteristics of long-distance travel by older adults: Older men and women take long-distance trips at about the same rates and show a strong preference for using personal vehicles. And, while men and women take an equal percentage of their trips by air, older women show a strong preference for bus travel. CONCLUSIONS: Although older Americans travel extensively, they are less mobile than their younger counterparts. This pattern is more pronounced among older women and among those with self-reported medical conditions that affect their ability to travel outside their home. Older women consistently take the least number of trips per day, have the lowest driving rates, travel the shortest distances, and are more likely to report medical conditions that limit their travel. For men and women who have to give up driving, alternative means of transportation becomes a necessity. Yet, use of alternative transportation is relatively low; excluding personal vehicle and walking, all other means of transportation account for about 2% of daily travel. Further, of those with medical conditions that affect their travel, only about 12% use special transportation services such as dial-a-ride.

Travel patterns and risk behaviour of HIV-positive people travelling internationally.

BACKGROUND: International travel is associated with an increased risk of enteric, vector-borne, sexually transmitted and blood-borne infections. These risks are even higher among immunocompromised people, such as those with HIV infection. We conducted a study to determine HIV-positive people's travel patterns and risk behaviours while abroad. METHODS: We conducted an anonymous survey of HIV-positive people attending an HIV clinic in a tertiary care hospital in Toronto about their travel activities and pretravel precautions as well as their burden of illness and risk exposure during travel. We compared the characteristics of respondents who had travelled outside Canada and the United States (international travellers) with those of respondents who had not travelled internationally. RESULTS: Of 290 HIV-positive people who participated in the study, 133 (45.9%) indicated that they had travelled internationally in the 5 years before the survey. These people were predominantly men (93.2%) and well educated (60.0% had a university level education), and they had travelled mostly for personal reasons (89.5%) on trips that lasted 3.6 weeks on average. Only 58 (43.6%) sought health advice before travelling, and only 17 (12.8%) sought advice from a travel clinic. Five (3.8%) had received live vaccines before travel, and 9 (6.8%) had taken malaria chemoprophylaxis. Of the 119 international travellers who were taking antiretroviral therapy; 35 (29.4%) reported either discontinuing their medications or being poorly compliant with the therapy while travelling. Thirty-one (23.3%) of the 133 international travellers reported having had casual sexual activity with new partners while travelling, and only 18 (58.1%) of them reported always using a condom. Twenty-one (15.8%) of the 133 reported having had risky exposure to sharps. Twenty-four (18.0%) said they had become ill enough while travelling to require medical attention. INTERPRETATION: Only one-fifth of HIV-positive people surveyed who travelled internationally sought advice from a health professional before their trip. Their travel was associated with poor adherence to antiretroviral therapy, risky sexual practices and risky exposure to sharps.

Travel insurance claims made by travelers from Australia.

BACKGROUND: Little is known about travel insurance claims made by travelers returning from abroad. This study was designed to investigate travel insurance claims made by travelers from Australia, particularly examining demographic factors, type of travel insurance coverage, nature and duration of travel, when treatment was sought during travel or when the problem arose, use of emergency assistance, nature of claim, and claim outcome, including cost. METHODS: A random sample of approximately one in five claims reported during the period 1996 to 1998 to a major Australian travel insurance company were examined. RESULTS: A total of 855 claims were examined, of which 42.6% (356/836) were made by male travelers and 57.1% (477/836) were made by female travelers. The majority of claimants were in the 55 years and over age groups (445/836, 53.2%). Medical and dental conditions accounted for 66.6% of claims (569/854), with the remainder associated with loss, theft, and damage (285/854, 33.4%). The most common medical conditions were respiratory (110/539, 20.4%), musculoskeletal (90/539, 16.7%), gastrointestinal (75/539, 13.9%), ear, nose, and throat (67/539, 12.4%), and dental conditions (39/539, 7.2%). Only one case of venous thrombosis was reported, secondary to a lower limb infection. Use of the travel insurance company's emergency telephone service was reported in 17.1% of claims (146/853). Almost two-thirds (559/853, 65.5%) of claims were fully accepted. Those who claimed medical treatment, assault, and theft were significantly more likely to have their claims accepted compared to those claiming dental conditions, cancellation, curtailment, loss and damage (chi2 = 127.78, df = 40, p <.00001). The majority of medical and dental conditions did not require further medical investigations (427/569, 75.0%). The mean cost of claim refunds was Australian dollars (AUD)991.31 (standard deviation [SD] 6 AUD5400.76) for males and AUD508.90 (SD 6 AUD1446.10) for females. Claims for assault, cancellation, and curtailment were significantly more expensive than other types of claims (Kruskal-Wallis one way analysis of variance [ANOVA]; chi2 = 106.87, df = 8, p <.00001). Claims for treatment of gastrointestinal, cerebrovascular, cardiovascular, musculoskeletal conditions, and pyrexias of unknown origin were significantly more expensive than other medical and dental claims (Kruskal-Wallis one way ANOVA; x2 = 61.68, df = 15, p <.00001). CONCLUSIONS: This explorative study highlights the importance of travelers taking out appropriate travel insurance. Claims for medical and dental conditions represent the majority of travel insurance claims made by Australian travelers returning from abroad, although travel insurance also covers against such contingencies as loss, theft, and cancellation. The most common medical conditions claimed were respiratory, musculoskeletal, and gastrointestinal disorders. Travelers should be advised to take out appropriate travel insurance before departure overseas and to take care with preexisting medical and dental conditions, which may not be able to be claimed against travel insurance.

Travel agents and the prevention of health problems among travelers in Québec.

BACKGROUND: Among the factors influencing travelers to seek preventive health advice before departure, the travel agent's recommendation plays an important role. The objective of our study was to document the practices and needs of travel agents in Québec (Canada) in relation to the prevention of health problems among travelers. METHODS: In June 2000, a cross-sectional descriptive survey was carried out among travel agents from all travel agencies in Québec. One agent per agency was asked to answer our questions. Data were collected using a 32-item telephone questionnaire. RESULTS: Altogether, 708 travel agents from the 948 agencies contacted answered our questionnaire (participation rate: 75%). Most respondents (81%) believed that the travel agent has a role to play in the prevention of health problems among travelers, especially to recommend that travelers consult a travel clinic before departure. Although over 80% of the agents interviewed mentioned recommending a visit to a travel clinic before an organized tour to Thailand or a backpacking trip in Mexico, less than half said they make the same recommendation for a stay in a seaside resort in Mexico. The majority of respondents were acquainted with the services offered in travel health clinics, and these clinics were the source of travel health information most often mentioned by travel agents. However, nearly 60% of the agents questioned had never personally consulted a travel clinic. When asked about the best way to receive information about travelers' health, more than 40% of respondents favoured receiving information newsletters from public health departments regularly whereas 28% preferred the Internet. CONCLUSION: Despite the limits of this study, our results should help the public health network better target its interventions aimed to inform travel agents on prevention of health problems among travelers.

Travel-related health problems of Hong Kong residents: Assessing the need for travel medicine services.

BACKGROUND: Although there has been a marked increase in travel among Hong Kong residents, travel-related health risks have not been well characterized nor has their use of travel medicine services. OBJECTIVES: To assess the travel health care needs of Chinese residents in Hong Kong by examining travel health problems of returning Hong Kong residents and by understanding their use of travel health services before or after travel. METHODS: Review of available data followed by a cross-sectional telephone survey of 280 travellers and 15 service providers. A structured pre-tested questionnaire was used for data collection. Household members, who were ethnic Chinese, aged 15-64 years, able to communicate in Cantonese, and who had travelled at least once during the preceding 12 months were invited to participate. RESULTS: There was a scarcity of travel medicine services in Hong Kong. The most common destinations for travellers were countries in the Asia-Pacific region, especially mainland China (33%). Twenty percent of the respondents developed health problems during or shortly after travel. Although only 9% of respondents had received pre-travel health advice, 61% used some form of precautions. Twelve percent had lost at least a day due to travel-related health problems. The service providers agreed that there are demands for travel health services. However, half of the service providers had not been trained in travel or tropical medicine. CONCLUSIONS: This study indicates the need for specialized travel medicine services in Hong Kong to improve the health of travellers.

Travellers' diarrhoea and the effect of pre-travel health advice in general practice.

BACKGROUND: Rates of travel-related diarrhoea vary from 8% to 50% depending on the country visited. Travellers' diarrhoea has social, health and economic costs. The impact of these may be reduced by relevant pre-travel advice. Little is known of the effect of pre-travel advice on the incidence of diarrhoea among travellers abroad. AIM: To determine the 'true' attack rate of travellers' diarrhoea and to assess the effectiveness of pre-travel health advice in reducing the incidence of diarrhoea and the need for subsequent GP consultation. METHOD: A retrospective study was carried out in a general practice in Stirling, Scotland, using a standardized, structured questionnaire to obtain demographic details and patients' home and foreign health experience in the previous 12 months. The questionnaire was administered to a 20% sample (n = 1771) of practice patients aged 16 years or over, stratified by age and sex. Main outcome measures were reported diarrhoeal illness while abroad, its management and outcome, and a record of diarrhoea in the two weeks prior to responding to the questionnaire. RESULTS: The response rate was 97% (n = 1649). Of those responding, 44% had travelled abroad in the past 12 months; 39% of travellers reported having diarrhoea while abroad, while 6% of the same group reported diarrhoea in the two weeks prior to being questioned; 9.7% of non-travellers reported diarrhoea in the two weeks prior to being questioned. Travellers were 6.5 times more likely to experience diarrhoea while abroad than when spending a comparable 2-week period at home. Travellers who had sought pre-travel advice were more likely to be travelling to a high-risk destination (P < 0.0001) and were more likely to suffer diarrhoea while abroad (P < 0.05); however, they were less likely to need medical help while abroad or on their return (P < 0.0001). The results indicate a markedly higher attack rate of diarrhoea in patients travelling abroad than would be expected if they stayed at home. CONCLUSION: Pre-travel advice does reduce the need for medical assistance while abroad; it also reduces GP work-load in terms of post-travel health consultations with returning travellers.

Specialized Travel Consultation Part I: Travelers' Prior Knowledge.

Studies have shown that more than one third of all travelers to tropical countries experience an illness while abroad. Naiveté about diseases, such as malaria, travelers' diarrhea, cholera, and HIV infections, appears to be the most crucial factor determining travel-related morbidity rates. A study was designed both to evaluate the level of disease-related, pretravel knowledge prior to a specialized travel clinic consultation as well as to correlate the level of knowledge with demographic and travel variables and previous travel experience. Using a self-administered questionnaire, data were collected from 167 clients who attended the Hospital for Tropical Diseases Travel Clinic, London, England, in June 1991. The questionnaire evaluated clients' knowledge and attitudes of travel-related diseases, their prevention and treatment, and the scores were analyzed using the Statistical Analysis System software, Version 5. Predictors for increased knowledge scores were examined by a one-way layout model comparing disease knowledge scores with variables such as sex, age, socioeconomic class, ethnic background, previous travel experience, type and duration of travel, destination, accommodation quality, and health insurance coverage. A step-down regression model was constructed to control for the effects of the many mutually confounding factors. Travelers' diarrhea and malaria risk at destination were acknowledged by more than 85% of the respondents, and 60% of the questions on travelers' diarrhea prevention, compared to 81% of those on malaria prevention, were answered correctly. Significantly, however, only one half of the respondents indicated that they would take appropriate measures concerning diarrhea while abroad. Stepwise regression identified previous travel experience, pretravel advice, traveling for work purposes, and using backpack overland tours as significant predictors of high knowledge. This study points out the necessity of pretravel education and that it should focus not only on malaria but also on other travel-related diseases like travelers' diarrhea. As well, target groups for whom more detailed information should be provided are identified, including inexperienced travelers, those using organized tours and sleeping indoors, those planning to visit friends or relatives, and those who have not received sufficient pretravel health advice.
