Pre-travel preparation practices among business travellers to tropical and subtropical destinations: Results from the Athens International Airport Survey

Characteristics and potential quality indicators for evaluating pre-travel consultations in Japan hospitals: the Japan Pretravel consultation registry (J-PRECOR)

Background

Awareness of pre-travel consultations (PTCs) and prevention methods for overseas travel-related diseases, and the understanding of PTCs among Japanese travelers and medical professionals remains low in Japan. A multicenter registry was established to examine PTCs in Japan. This study assessed the PTC implementation rate and examined the indicators of PTCs that can be used as criteria for evaluating quality.

Methods

Clients who presented for their PTCs at 17 facilities and were registered between February 1, 2018, and May 31, 2020, were included. Medical information was extracted retrospectively via a web-based system. Correlations between vaccination risk categories and advice/intervention proportions by the facility were evaluated using Spearman’s ordered phase relations (α = 0.05).

Results

Of the 9700 eligible clients (median age, 32 years; 880 [9.1%] aged < 16 years and 549 [5.7%] aged ≥65 years), the most common travel duration was ≥181 days (35.8%); higher among younger clients. The most common reason for travel was business (40.5%); the US (1118 [11.5%]) and Asia (4008 [41.3%]) were the most common destinations and continents, respectively. The vaccine number (median three per person) increased after the PTCs except for the tetanus toxoid. Only 60.8% of the clients recommended for malaria prophylaxis received anti-malarial agents. The gross national income; the incidence of human rabies, typhoid fever, falciparum malaria; and dengue risk category were associated with the percentage of hepatitis-A vaccines; explaining rabies post-exposure prophylaxis, typhoid-fever vaccinations, malaria-prophylaxis prescriptions; and mosquito repellants, respectively.

Conclusions

Although the characteristics of the travelers differed, the quality of the PTCs should be improved to address, for example, the lower rate of acceptance of malaria prophylaxis in Japan.

Comprehensive Travel Health Education for Tour Guides: Protocol for an Exploratory Sequential Mixed Methods Research

Background

Tourists are at risk of experiencing health problems during their travel. However, even though tour guides have the potential to become travel health promoters, their participation has not been optimal.

Objective

This study aims to develop a comprehensive travel health education model to help tour guides improve health information delivery to tourists.

Methods

This is an exploratory sequential mixed methods research. The first phase consisted of a qualitative study with an informed grounded theory design. In-depth interviews were carried out with tour guides from all language divisions and policymakers of the Indonesian Tour Guide Association Bali Branch or Himpunan Pramuwisata Indonesia Daerah Bali (HPI Bali). The interview guidelines were developed based on the theory of planned behavior and identity theory. Qualitative data were analyzed thematically. In the interim phase, a travel health education model and questionnaire were developed based on the qualitative findings. The initial model and its instruments were finetuned after consultation with travel medicine and health promotion experts. Furthermore, the validity and reliability of the questionnaire were tested on 30 tour guides. The second phase consisted of a quantitative study with a randomized pretest-posttest control group design. A total of 76 tour guides in the intervention group received comprehensive travel health education, while 76 in the control group received no specific intervention. Outcome variables (ie, attitudes, subjective norms, perceived behavioral control, actual behavioral control, role identity, and behavioral intention) were measured at baseline (T0), after the online training (T1), before information sharing via WhatsApp (T2), a month after the start of the WhatsApp intervention (T3), and at the end of the WhatsApp intervention (T4). The mean difference of each outcome variable before and after the intervention will be compared between the intervention and control groups. Thereafter, the quantitative and qualitative findings will be integrated into a joint display.

Results

The qualitative phase was conducted through in-depth interviews with 21 informants who included tour guides and policymakers from HPI Bali from May to June 2021. The education model, educational materials, and questionnaire were developed based on the qualitative findings and consultation with experts. The education model consists of online training and information sharing through WhatsApp and was trialed with tour guides from November 2021 to February 2022. As of April 2022, this study is in the quantitative data analysis stage.

Conclusions

A travel health education model was developed based on qualitative findings and consultation with experts. The model was tested with tour guides, and a series of self-administered questionnaires were completed. This study is in the quantitative data analysis stage and will continue by integrating qualitative and quantitative findings into a joint display.

A Normative Behavior of Pre-Travel Health Consultation and the Associated Factors among Travelers

Introduction: Travelers may transmit diseases due to their behavior of travel, consequently travelers should consider preventive measurement through pre-travel health consultation seeking behavior. Pre-travel health consultation is a particular preparation ideally conducted by international travelers to obtain risk assessment and management to prevent the transmission of diseases. This study investigates the relationship of socio-demographic characteristics and itinerary on pre-travel health consultation behavior among international travelers in Badung, Bali.Methods: A descriptive-correlative design using a cross-sectional approach employed 125 participants determined by a purposive sampling technique performed in the ten tourist destinations of Badung Regency. Data collection was conducted on February 15th until March 5th, 2020. Data demography, travel plan, and anonymous questionnaires regarding pre-travel health consultation behavior are used in this research. The Gamma coefficient correlation and Kruskal-Wallis statistic tests were performed in the study for bivariate analysis.Results: The results showed that age (p<0.0001; r=-0.650) and past-travel history to Bali (p=0.004; r=-0.475) were significantly correlated with pre-travel health consultation behavior among international travelers in Badung, Bali. Meanwhile sex, nationality, last education, travel duration, and types of the destination visited were not significantly associated with pre-travel health consultation behavior among international travelers in Badung, Bali (p>0.05).Conclusion: The age and past-travel history to Bali seem to be predictors for travelers to uptake pre-travel health consultation, thus nurses should be able to promote the implementation of pre-travel health consultation by utilizing the media promotion appropriately adjusted to the age of travelers and travel experience.

Determinants of Compliance of Travelers with Vaccination and Malaria Prophylaxis at a Travel Clinic

BACKGROUND

Pre-travel medical consultation is essential to reduce health impairment during travel. Yellow fever vaccination (YFV) is mandatory to enter some endemic countries. In this study, we evaluated the factors that affect compliance with appropriate prevention of infectious diseases in travelers who visited clinic for YFV.

METHODS

For this retrospective study, chart reviews for 658 patients who visited a travel clinic for YFV before travel were conducted. The period of this study was from January 2016 to September 2018. The associations between appropriate vaccination and factors such as travel duration, destination, time of visiting clinic before departure, and purpose of travel were analyzed.

RESULTS

Among 658 patients who got YFV during the study period, 344 patients (52.3%) received additional vaccination or malaria prophylaxis following a physician's recommendation. Travelers who visited the clinic more than 21 days before departure were more compliant than those who visited 14 days or fewer before departure (odds ratio [OR], 1.90; 95% confidence interval [CI], 1.23-2.93; P = 0.004). Travelers visiting Africa were more compliant than were those traveling to South and Central America (OR, 1.97; 95% CI, 1.34-2.90; P = 0.001). Travelers in age groups of 40-49 years and over 70 years were less compliant than the 18-29 years old population (OR, 0.51; 95% CI, 0.28-0.93; P = 0.027 and OR, 0.19; 95% CI, 0.04-0.84; P = 0.03, respectively). Also, those who traveled for tour or to visit friends or relatives were more compliant than those who departed for business (OR, 0.77; 95% CI, 1.03-3.56; P = 0.04).

CONCLUSION

For appropriate vaccination, pre-travel consultation at least 3 weeks before departure is crucial. Travelers should be aware of required vaccination and malaria prophylaxis before visiting South and Central America and Asia. Plans to enhance compliance of the elderly and business travelers should be contrived.

Perceptions of tick-borne encephalitis risk: a survey of travellers and travel clinics from Canada, Germany, Sweden and the UK

BACKGROUND

While the worldwide endemicity of tick-borne encephalitis (TBE) has been increasing, a lack of awareness of the risks of this life-threatening disease may be leading to an underutilization of preventive measures among travellers to TBE-endemic regions. This study's objectives were to assess travellers' awareness of TBE and advice-seeking attitudes, and to evaluate practices of travel clinics regarding pre-travel advice.

METHODS

We used an online questionnaire to identify individuals aged 18-65 years residing in the UK, Germany, Canada and Sweden, who had travelled to TBE-endemic countries between 2013 and 2016. This sample was defined as the visit-risk sample. Of these, the first 375 respondents who reported that they had engaged in pre-defined at-risk activities (e.g. hiking in forests) were asked to complete an additional online survey and were included in the activity-risk sub-sample. We also used an online/phone questionnaire to interview travel clinic personnel.

RESULTS

The TBE visit-risk sample included 4375 individuals; 69% had heard of the disease and 32% had heard of a TBE vaccine. Before travelling, travellers most commonly sought information online (26%); fewer travellers consulted family doctors (8%) or travel clinics (5%). In the activity-risk sample, 79% of the travellers were aware of at least one correct TBE prevention measure; however, only 15% reported being vaccinated within the past 3 years, with 11% of vaccinated travellers doing so following a clinic's recommendation. One hundred and eighty travel clinic representatives responded and reported that TBE vaccination was recommended to an average of 61% of travellers to endemic regions. Vaccination-reminder services such as follow-up appointments, e-mail and text reminders were offered by 50% of the clinics.

CONCLUSIONS

There is a need to increase awareness of the risk and prevention of TBE among travellers to endemic countries, and travel clinics could play an important role in this process. 5975671594001tay062media15975671594001.

HAV & HBV vaccination among travellers participating in the National Health and Wellness Survey in five European countries

BACKGROUND

A main cause of hepatitis A and B infections in European countries is travel to endemic countries. Most research on hepatitis vaccination among travellers from Europe has been conducted in airports or travel clinics, samples which potentially overrepresented frequent travellers.

METHODS

2102 respondents across France, Germany, Italy, Spain, and UK completed an internet-based questionnaire. Vaccination status, travel to endemic countries, and other characteristics were compared across frequent, occasional, and non-travellers. Logistic regressions tested association between vaccination and travel adjusting for potential confounders.

RESULTS

Most respondents were occasional travellers (61%) and 24% were frequent travellers. Frequent travellers had 2.3-2.4 times the odds of being vaccinated relative to non-travellers, and odds of vaccination were 2.5-3.1 times higher among travellers to endemic areas relative to others (all p < .05). Frequent travellers were more aware of their vaccination status (HAV: 80% vs. 72%; HBV: 82% vs. 74%), though many who were vaccinated could not identify the number of injections to complete the series (47% vs. 29%) (all p < .05).

CONCLUSION

Travel frequency and destination endemicity are associated with increased hepatitis A and B vaccination. The number of unvaccinated travellers and the lack of recall for the dosing schedule suggest the need to improve travellers' awareness and adherence to recommendations.

Meningococcal vaccination for international travellers from Greece visiting developing countries

BACKGROUND

Meningococcal meningitis is a serious disease. Travel-associated infection for the general traveller is low; however regular epidemics in indigenous population, particularly in sub-Saharan Africa are responsible for significant morbidity and mortality. Our aim was to assess meningococcal vaccination for international travellers from Greece.

METHODS

A prospective questionnaire-based study was conducted during 2009-2013.

RESULTS

A total of 5283 travellers were studied (median age: 39.2 years); Meningococcal tetravalent vaccine (A,C,W135,Y) was delivered to 1150 (21.8%) of them. Of those who travelled to the Middle East and sub-Saharan Africa, 73.1% and 21.2% received meningococcal vaccine, respectively. Of those travellers who travelled to sub-Saharan Africa from November to June and from July to October, 22.1% and 20.6% were vaccinated with meningococcal vaccine, respectively. Of all travellers who travelled for <1 month and ≥1 month, 23.3%, and 20.5%, were vaccinated, respectively. Meningococcal vaccine was administered to 95.3% of pilgrims, 17.4% of those visiting friends and relatives (VFRs), 16.7% of those who travelled for recreation, and 13.8% of those who travelled for work. Of travellers who stayed in urban, in rural, and in urban and rural areas, 32%, 11.6% and 12.7% were vaccinated, respectively. Meningococcal vaccine was delivered to 29.2%, 21.1%, 19.4% and 5.1% of those who stayed in hotels, at local people's home, in camps, and on ships, respectively. The association of meningococcal vaccine administration with the destination, duration and purpose of travel, area of stay and type of accommodation was statistically significant.

CONCLUSION

There is a need to improve meningococcal vaccine recommendations for travellers from Greece, particularly for high risk populations, such as VFRs, business travellers and those visiting sub-Saharan Africa especially during the dry season.

Pre-travel advice concerning vector-borne diseases received by travelers prior to visiting Cuzco, Peru

Peru is an increasingly popular tourist destination that poses a risk to travelers due to endemic vector-borne diseases (VBDs). The objective of our study was to determine which factors are associated with receiving pre-travel advice (PTA) for VBDs among travelers visiting Cuzco, Peru. A cross-sectional secondary analysis based on data from a survey among travelers departing Cuzco at Alejandro Velazco Astete International Airport during the period January-March 2012 was conducted. From the 1819 travelers included in the original study, 1717 were included in secondary data analysis. Of these participants, 42.2% received PTA and 2.9% were informed about vector-borne diseases, including yellow fever (1.8%), malaria (1.6%) and dengue fever (0.1%). Receiving information on VBDs was associated with visiting areas endemic to yellow fever and dengue fever in Peru. The only disease travelers received specific recommendations for before visiting an endemic area for was yellow fever. Only 1 in 30 tourists received information on VBD prevention; few of those who traveled to an endemic area were warned about specific risks for infectious diseases prior to their trip. These important findings show that most tourists who travel to Peru do not receive PTA for the prevention of infectious and VBD, which can affect not only the travelers but their countries of origin as well.

Has the economic crisis led to a new risk profile for international travellers?

INTRODUCTION

The economic world crisis has led to the migration of European workers to developing countries with a high incidence of infectious diseases. The objective of this study was to assess whether this context has produced an increase in the risks to international travellers for work reasons (TWR).

METHODS

Observational, retrospective study. The study population included TWR who were attended before travelling at an International Health Unit in the year 2007 (the year before the initiation of the European crisis) and in the year 2012 (when the structural crisis was established). A comparative socioeconomic analysis was performed as well as an analysis of the risk factors present in both groups.

RESULTS

In 2007 and 2012 a total of 9,197 travellers were attended. Of these, there were 344 TWR (3.4%); 101 TWR (2.8%) in 2007 and 243 TWR (4.5%) in 2012 (p<0.001). The average age of the travellers was 38.1 years (SD: 10.57). The most common destination was Sub-Saharan Africa, in 164 (47.6%) of the cases. Malaria chemoprophylaxis was prescribed to 152 travellers (44%) and 80 presented comorbidity (23.25%). The TWR from 2012 presented a significantly greater age (p=0.05), more comorbidity (p=0.018) and a greater proportion of stays in rural areas (p=0.0009) for longer time periods (p=0.001).

CONCLUSIONS

At 5 years from the start of the economic crisis, there was a change in the profile of TWR. Their number has increased significantly, as has the proportion who present risk factors for contracting imported diseases. The International Health Units should adapt to these new circumstances and adopt preventive measures for this population.

Middle East respiratory syndrome coronavirus (MERS-CoV): prevention in travelers

Middle East respiratory syndrome coronavirus (MERS-CoV), a novel coronavirus that causes a severe lower respiratory tract infection in humans, emerged in the Middle East in 2012. Since then, MERS-CoV has caused an ongoing epidemic in the Arabian Peninsula with sporadic cases imported in Europe, North Africa, Southeast Asia, and the United States of America. As of 28th May 2014, 636 laboratory-confirmed cases of infection with MERS-CoV have been reported to World Health Organization including 14 cases imported by travelers. The epicenter of the current MERS-CoV epidemic is located in Saudi Arabia, where millions of pilgrims travel for two mass gatherings annually. In this review we summarize MERS-CoV cases in relation to travel with focus on the epidemiology and prevention in travelers. It is important to increase awareness of travelers about the risks and appropriate preventive measures and for health professionals to be on alert if a patient with severe respiratory symptoms reports a recent history of travel to the region affected with MERS-CoV. Measures should be taken by local health authorities of the affected countries in order to improve hospital hygiene. Finally, it is crucial to investigate the reasons for travelers' poor compliance with rules and recommendations issued by Saudi officials and to take appropriate measures in order to improve them.
