Pre-travel Consultation Research Articles

Trend Analysis of Travel Medicine Topics Presented at an International Tropical Medicine Conference.

Prior to the COVID-19 pandemic, there was a rapid increase in international travel. Travel medicine is a branch of preventive medicine focusing on risk assessment pre-travel, during travel and post-travel with the aim of promoting health and preventing adverse health outcomes. Travel medicine specialists inform travelers about potential health risks and mitigate infectious disease risks such as travelers' diarrhea, yellow fever, and malaria. Travel medicine topics were popular in the American Society of Tropical Medicine and Hygiene conferences between 2016 and 2020, and now comprise approximately 2% of all presentations. Most topics related to the post-travel assessment (44%), followed by diseases contracted during travel (24%), and pre-travel assessment and consultation (23%). Our analysis of the 10 sub-domains of travel medicine issues found that malaria (26%) and immunization (12%) were represented to the greatest extent. We anticipate that both travel and tropical medicine fields will regain their popularity after recovery from the pandemic.

High-risk US International Travelers Seeking Pretravel Consultation During the COVID-19 Pandemic.

BackgroundTo assess the implications of coronavirus disease 2019 (COVID-19)–related travel disruptions, we compared demographics and travel-related circumstances of US travelers seeking pretravel consultation regarding international travel at US Global TravEpiNet (GTEN) sites before and after the initiation of COVID-19 travel warnings.MethodsWe analyzed data in the GTEN database regarding traveler demographics and travel-related circumstances with standard questionnaires in the pre-COVID-19 period (January–December 2019) and the COVID-19 period (April 2020–March 2021), excluding travelers from January to March 2020. We conducted descriptive analyses of differences in demographics, travel-related circumstances, routine and travel-related vaccinations, and medications.ResultsCompared with 16 903 consultations in the pre-COVID-19 period, only 1564 consultations were recorded at GTEN sites during the COVID-19 period (90% reduction), with a greater proportion of travelers visiting friends and relatives (501/1564 [32%] vs 1525/16 903 [9%]), individuals traveling for >28 days (824/1564 [53%] vs 2522/16 903 [15%]), young children (6 mo–<6 y: 168/1564 [11%] vs 500/16 903 [3%]), and individuals traveling to Africa (1084/1564 [69%] vs 8049/16 903 [48%]). A smaller percentage of vaccine-eligible travelers received vaccines at pretravel consultations during the COVID-19 period than before, except for yellow fever and Japanese encephalitis vaccinations.ConclusionsCompared with the pre-COVID-19 period, a greater proportion of travelers during the COVID-19 period were young children, were planning to visit friends and relatives, were traveling for >28 days, or were traveling to Africa, which are circumstances that contribute to high risk for travel-related infections. Fewer vaccine-eligible travelers were administered travel-related vaccines at pretravel consultations. Counseling and vaccination focused on high-risk international travelers must be prioritized during the COVID-19 pandemic.

Advising travellers beyond infectious diseases: Can we learn from our forebears?

The pre-travel consultation is usually dominated by discussion and advice on preventing infectious diseases. Yet, they account for only a few percent of deaths during travel. It is important the Travel Medicine practitioner looks beyond infectious diseases and advises on environmental harms, including the importance of road traffic incidents.

Adherence and Health Problems in Thai Travellers Living with HIV.

It is important to focus on adherence to antiretroviral therapy (ART) and health problems of travellers living with HIV (TLWHIV) during travel. This study was conducted to investigate factors related to adherence and health problems among TLWHIV. This multicentre, cross-sectional observational study was conducted among TLWHIV in university hospitals from August 2019 to July 2020. Factors associated with adherence to ART were evaluated using a logistic regression model. Health problems and risk exposure were also examined among participants during travel. Of 321 TLWHIV, 20 (6.23%) showed moderate-to-poor adherence, among whom 3 (15%) had viral rebound after travelling. Travellers frequently missed ART during the first 3 days of their trip. International destination was associated with moderate-to-poor adherence. In total, 237 (73.8%) travellers reported health problems during travel, among whom 36 required medical attention. Sexual or sharp exposure was found in <5% of travellers during travel. Approximately 95% of Thai TLWHIV had good ART adherence. International destination was the major factor determining adherence. TLWHIV should be encouraged to seek pretravel consultation. Healthcare providers should discuss health risk prevention and teach about ART dosing during travel to enhance adherence and minimise toxicity.

Pretravel preparation and factors associated with willingness to seek pretravel consultation among Taiwanese travelers

BackgroundAlthough globalization promotes economic development, cross-border infectious disease transmission is still a serious threat to health. Taiwan is geographically close to Southeast and South Asia, but the needs and expectations of Taiwanese travelers with regard to travel medicine are still largely unknown. This study aimed to clarify the pretravel preparations, needs, willingness to seek pretravel consultation, and factors associated with willingness, in order to provide valuable information for improvement of healthcare service. MethodsData were collected with anonymous structured questionnaires distributed to 477 visitors who tried to get travel health information from New Southbound Health Center between June and November 2019. A multivariate stepwise logistic regression analysis was applied to identify factors associated with the visitors’ willingness to seek pretravel consultation. ResultsA total of 304 questionnaires (64%) were collected. Eighty-three percent of the respondents were willing to seek pretravel consultation. A higher level of education (odds ratio 3.6 [95% CI 1.58–8.22]), having a plan to obtain travel medical insurance (2.5 [1.18–5.28]), concern with gastrointestinal diseases (2.0 [1.04–3.94]), concern with mosquito-borne diseases (2.0 [2.07–3.95]), and concern with noncommunicable diseases (2.2 [1.02–4.96]) were independent factors associated with willingness to seek pretravel consultation.: ConclusionsWe found that most of the travelers were willing to seek pretravel consultation. Our study highlighted the need to enhance awareness about travel-related illness among these travelers. Strategies should be tailored according to these findings to help prevent epidemics and improve healthcare service in the future.

Parasomnias during trans-meridian and long-distance travel: Critical literature review and clinical practice recommendations.

Parasomnias are undesirable events that occur during sleep. They can be classified into rapid eye movement parasomnias and non-rapid eye movement parasomnias. Those who experience parasomnias may be anxious about travel for many reasons, including the occurrence of unwanted events during the trip, increased exposure to environmental trigger factors, and the propensity for harm to occur due to unfamiliar surroundings while travelling. There is a paucity of literature examining this area. This review summarizes the relevant literature and the clinical experience of the authors to compile clinical practice recommendations. The clinical features of parasomnias and how they relate to trans-meridian and long-distance travel are described. Triggers for non-rapid eye movement parasomnias, particularly the use of sedative hypnotic drugs, alcohol, drug withdrawal, sleep deprivation, emotional stress and environmental stimulations, are described. Management of parasomnias whilst travelling is reviewed, with a particular focus on trigger minimalization. The role for clonazepam and melatonin is outlined. At the pre-travel health consultation, the physician is strongly advised to screen the traveller for co-morbid sleep conditions, which exacerbate parasomnias. Areas for further research are explored, including the extent to which these sleep disorders impact on the travel experience.

Travel patterns and advice-seeking behaviour of pregnant women in the Australian context: A multicentre cross-sectional analysis.

Travel poses risks to pregnant women, but little data exist describing the travel habits of women during pregnancy or pre-travel recommendations given. To examine travel patterns of pregnant women including frequency of pre-travel consultation, and advice recalled. Cross-sectional analysis of post-partum women admitted to five Victorian maternity hospitals between 21 May 2019 and 22 April 2020 in Australia. Forty-four percent (182/410) of women travelled during pregnancy, 32.9% (135/410) interstate and 19.5% (80/410) internationally. Fifty-five percent travelled for leisure (118/215) and 27% to visit friends/relatives (58/215). Overall, 68.1% (124/182) sought pre-travel advice, primarily from an obstetrician (60.5%, 75/124) or general practitioner (29.8%, 37/124). Only one woman attended a travel clinic. The most common reason for not seeking pre-travel advice was the belief that travel posed no risk (63.4%, 45/71). Pre-travel advice was sought least by those visiting friends/relatives (61.4%, 35/57). Women recalled recommendations regarding travel restrictions by gestational age and venous thromboembolism precautions, but not infectious disease prevention for those to whom it was relevant. Of international travellers, 48.8% (39/80) sought advice from the internet, one-third (13/39) as an alternative to seeing a healthcare provider. Travel is common during pregnancy and women seek pre-travel advice from the healthcare provider they see most often during pregnancy. All pregnant women should be provided with consistent, evidence-based pre-travel advice regardless of whom they consult. Further work is needed to educate and provide resources to maternity care providers to optimise pre-travel counselling.

Primary care physicians' knowledge of travel vaccine and malaria chemoprophylaxis and associated predictors in Qatar.

In an era of globalization, travel-related illnesses have become a focus of public ‎health concern, especially in the Arab region where travel health services are insufficient and ‎not well-established. This study was conducted to assess travel vaccine and ‎malaria chemoprophylaxis knowledge and associated predictors among primary care physicians‎ (PCPs) in ‎Qatar. This was a cross-sectional study. A structured questionnaire was used to collect ‎data from all physicians working at all 27 primary healthcare centers from March 1st to May 31st 2020.‎ Knowledge scores were computed and a multivariable linear regression model was built to identify predictors of higher knowledge. A total of 364 PCPs participated (response rate of 89.2%). Participants' mean ‎age was 44.5 (±7.8) with 59.1% being males. Their overall mean knowledge score was 9.54/16 (±3.24). Significant predictors of higher knowledge included: aged 40-49 years ‎(1.072; 95% CI: 0.230, 1.915)‎, had medical degree from non-Arab countries ‏‎(0.748; 95% CI: 0.065, ‎‎1.432)‎‏,‏‎ had training in TM ‏ ‏‎(1.405; 95% CI: 0.407, ‎‎2.403), and provided ≥10 consultations/ month ‎(2.585; 95% CI:1.294, 3.876)‎. Online information was the main reported resource of travel medicine consultation. The overall PCPs' mean percentage knowledge score of travel medicine was 59.6% (±20.3). A high volume of pretravel consultation, prior training, middle age group, and medical degree from non-Arab countries were significant predictors of higher ‎knowledge. Continuing ‎education and training provided by recognised international institutions for all PCPs is highly ‎recommended to narrow the gap in travel medicine knowledge.

Ready-To-Go Questionnaire - Development and validation of a novel medical pre-travel risk stratification tool

BackgroundThere are no validated pre-travel self-assessment tools to stratify travellers' health risks and identify their needs for pre-travel medical preparation. This study presents a novel pre-travel risk stratification tool (Ready-To-Go Questionnaire). MethodsThe Ready-To-Go Questionnaire was developed by travel medical experts. It assesses information on travellers' itinerary and current health status, thereby assigning travellers to one out of four risk categories. To explore the Ready-To-Go Questionnaire's validity, we analysed the agreement between the risk categories resulting from the questionnaire and predefined validation criteria. This study was carried out at the Travel Clinic, University of Zurich, Switzerland. ResultsOne hundred travellers attending a pre-travel consultation were included. 82% corresponded to the substantial-risk category, 17% to the high-risk category, 1% to the moderate-risk category and 0% to the low-risk category. The concordance between the risk categories and the consultants' risk assessment, was 0.39 and 0.29 (unweighted/weighted Cohen's Kappa). No significant concordance was found between the risk categories and additional validation criteria. ConclusionThe Ready-To-Go Questionnaire is a medical triage tool developed to identify different levels of travel-related health risks. This tool assists in better understanding travellers' needs, shaping modern travel consultations and offering patient-centred travel medicine services.

Key informant perspectives on sexual health services for travelling young adults: a qualitative study

BackgroundInternational travel has become increasingly popular among young adults. Young adults often engage in casual sexual relationships abroad, exhibit sexual risk behaviours and may thus be at risk of contracting sexually transmitted and blood-borne infections. Pre-travel interventions and consultations may mitigate this risk. At present, we know little about sexual health-related pre-travel interventions. The aim of this study was therefore to document key informants’ experiences, perceptions and recommendations in the context of sexual health of young adult travellers.MethodsKey informants were professionals working in Ottawa, Canada travel clinics, travel organizations or sexual health clinics with a young adult clientele. This study used a qualitative approach and consisted of 13 in-person or Skype semi-structured interviews with key informants. Thematic content analysis was informed by a sexual health framework, with themes emerging both inductively and deductively.ResultsSexual health was not common in pre-travel interventions described by key informants. Risk-assessment, and practical or purpose-driven pre-travel interventions were identified, resulting in risk mitigation strategies tailored to the destination region and/or mission/culture of the travel organization. Dissemination (e.g. limited time, lack of training) and uptake (e.g. young adults’ embarrassment, provider discomfort, financial constraints) barriers limited in-depth discussions of pre-travel interventions related to sexual health. Key informants acknowledged the importance of early sexual health education, and recommended ongoing, comprehensive sexual education for both youth and young adults.ConclusionThe findings of this study suggest that more time and resources should be allocated to the topic of sexual health during pre-travel interventions with young adults. Professionals who guide and prepare young adults for travel must develop concomitant skills in sexual health promotion. Early, comprehensive sexual education is recommended to improve overall sexual health in young adults and mitigate risk behaviours during travel.

Pretravel plans and discrepant trip experiences among travelers attending a tertiary care centre family travel medicine clinic.

International travel can expose travelers to a number of health risks. Pretravel consultation (PC) helps mitigate risk and prepare travelers for health concerns that might arise. The assessment of risk, mitigation strategies, and relevance of pretravel advice is dependent on how closely travelers adhere to their planned travel itinerary and activities. We determined the proportion of returned travelers whose completed travel experiences differed from their stated travel itineraries, and identified discrepancies that significantly altered the traveler's health risk and would have required alternative counseling during their PC. We conducted a prospective cohort study at the SickKids' Family Travel Clinic between October 2014 and November 2015. Returned travelers who completed a post-travel survey were included. Pretravel consultation assessments and post-trip surveys were compared to identify discrepant trip experiences. A total of 389 travelers presented to the clinic for a PC during the study period and 302 (77.6%) were enrolled. Post-travel surveys were received from 119 (39.4%) participants, representing 101 unique itineraries. The median participant age was 36.3 years (IQR 26.6-47.5) and there were 73 female travelers (61%). Most participants (n = 87,73%) were healthy as well as Canadian born (n = 84, 71%). A quarter of travelers were visiting friends and relatives (VFR) (n = 30, 25.2%). The vast majority of returned travelers (n = 109, 92%) reported discrepant trip experiences involving trip duration, countries visited, accommodations, environmental surroundings and/or activities. Almost two thirds of these individuals (n = 68, 62%) would have required alternative pretravel counseling. We did not identify any demographic or planned trip characteristics that predicted discrepant trip experiences requiring alternative pretravel counseling. The majority of travelers reported discrepant trip experiences and the discrepancies often affected health risk. Therefore, clinicians should consider providing broader counselling during the PC as discrepancies from planned travel are common.

Acute hepatitis A in international travellers: a GeoSentinel analysis, 2008-2020.

BackgroundNon-immune international travellers are at risk of acquiring hepatitis A. Although hepatitis A vaccination is recommended for unvaccinated travellers to high or intermediate hepatitis A virus endemicity, compliance with this recommendation is not universal.The main objective was to describe the demographic and travel characteristics of international travellers infected with hepatitis A during travel.MethodsAvailable data on travellers with confirmed (positive molecular test) or probable (symptomatic individuals with a single positive IgM test) hepatitis A diagnosed during and after travel from January 2008 to December 2020 were obtained from the GeoSentinel Surveillance Network database. We analysed demographic and travel characteristics of infected travellers.ResultsAmong 254 travellers with hepatitis A (185 confirmed and 69 probable), the median age was 28 years (interquartile range: 19–40), 150 (59%) were male, and among 54 travellers with information available, 53 (98%) were unvaccinated. The most common reasons for travel included tourism (n = 120; 47%) and visiting friends or relatives (VFR; n = 72; 28%). About two-thirds of VFR travellers with hepatitis A (n = 50; 69%) were younger than 20 years old. Hepatitis A was acquired most frequently in South-Central Asia (n = 63; 25%) and sub-Saharan Africa (n = 61; 24%), but 16 travellers (6%) acquired hepatitis A in regions with low endemicity including Western Europe (n = 7; 3%), the Caribbean (n = 6; 2%) and North America (n = 3; 1%). Median duration from illness onset to GeoSentinel site presentation was ~7 days (interquartile range : 4–14 days). Among 88 travellers with information available, 59% were hospitalized.ConclusionsDespite availability of highly effective vaccines, travellers still acquire hepatitis A, even when traveling to low-endemicity destinations. Providing pre-departure hepatitis A vaccine to susceptible travellers is crucial to reducing travel-associated hepatitis A and should be offered to all travellers as part of the pre-travel consultation, regardless of destination.

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

BackgroundAwareness 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.MethodsClients 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).ResultsOf 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.ConclusionsAlthough 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.

Health Problems Encountered by Short-Term European Volunteers in a Nongovernmental Organization in Cambodia.

Short-term volunteers are susceptible to a wide spectrum of morbidities, mostly infectious diseases preventable with general hygiene and preventive measures. This study aimed to identify the health problems encountered by European short-term volunteers collaborating for 1 month with a nongovernmental organization (NGO) in Cambodia and to describe their characteristics. A prospective, descriptive observational study was conducted on short-term volunteers who collaborated with an NGO in Cambodia during August 2018. Informed consent and sociodemographic, clinical, and preventative health-related questionnaire data were provided by 198 volunteers. The health problems encountered were confirmed in a primary care consultation with healthcare professionals. Univariate and bivariate analyses were performed. The median age of the volunteers was 22 years (interquartile range = 21-24), and 64% were women. Some (18.2%) had allergies, 8.6% had preexisting health conditions, and 10.6% were under regular treatment. A total of 77.3% visited a pretravel consultation clinic, 39.9% completed a specific pretravel health course, 21.7% took malaria prophylaxis, 92.4% received hepatitis A vaccination, and 82.3% received typhoid fever vaccination. Medical assistance was sought by 112 (57.3%) of the volunteers. The average number of health problems was 2.5 (standard deviation = 1.5), and the total number of health problems attended by the medical team was 279. The most common health problems were upper respiratory infections (12.2 per 1,000 person/days), wounds (10.8 per 1,000 person/days), and diarrhea (6.3 per 1,000 person/days). Short-term volunteers experienced a high rate of health problems during their stay in Cambodia, but most of the problems were mild and preventable and resolved quickly. Pretravel consultation and specific pretravel health training seemed to increase disease awareness.

Collateral effects of the COVID-19 pandemic on the practice of tropical and travel medicine

Undoubtedly, the COVID-19 pandemic has had impacts in many areas, including travel and by extension on daily practice in tropical and travel medicine. The intercontinental travelers in decline have been replaced by a new population of travelers who previously did not require specific consultations. SARS-CoV-2 has earned its place in the pre-travel consultation in view of the medical and administrative implications. Furthermore, the global health effects of the pandemic are broader than its direct medical consequences and should not be underestimated. The increase in malaria mortality worldwide is just one example. Preventive measures prior to exposure are more important than ever.

Eco-tourism: what recommendations?

Which recommendations family doctors and travel health practitioners can provide to their patients, to reduce their environmental footprint when travelling? Avoiding flying is the biggest action a traveler can take to reduce their greenhouse gas emissions. Staying at eco-lodges, or carbon offsetting, may help, but one must be aware of false or exaggerated claims on their impact. Using UV light, filters, halogens or boiling water, are effective ways to disinfect water and reduce the waste created from plastic water bottles. Given the large carbon footprint of medications and laboratory exams, limiting prescription of antibiotics or antimalarials in pre-travel consultations, or limiting unnecessary laboratory exams in returning travelers by following the latest recommendations, could reduce greenhouse emissions of the medical practice.

Pretravel Preparation and Factors Associated with Willingness to Seek Pretravel Consultation Among Taiwanese Travelers

Pretravel Preparation and Factors Associated with Willingness to Seek Pretravel Consultation Among Taiwanese Travelers

738. Comparison of Characteristics of US International Travelers Seeking Pretravel Health Consultations at US Global TravEpiNet Sites Before and During the COVID-19 Pandemic

BackgroundIn January–March 2020, the Centers for Disease Control and Prevention (CDC) issued multiple warnings regarding COVID-19 travel-associated risks. We sought to describe US travelers seeking pretravel consultation regarding international travel at US Global TravEpiNet (GTEN) sites before and after the initial COVID-19 travel warnings.MethodsWe prospectively collected data at 22 GTEN sites pre-COVID-19 (January–December 2019) and 18 GTEN sites during the COVID-19 pandemic (April 2020–March 2021). We excluded travelers evaluated during January–March 2020, when CDC travel guidance was evolving rapidly. Travelers used standardized questionnaires to self-report data regarding demographics and travel-related characteristics. Providers confirmed these data and documented their recommendations during pretravel consultation, which could be performed virtually. We conducted descriptive analyses of differences in demographics, travel-related characteristics, vaccinations, and medications (SAS v9.4; Cary, NC). ResultsCompared with 16,903 pre-COVID-19 consultations, only 1,564 consultations occurred during the COVID-19 pandemic, a 90% reduction (Table). During COVID-19, a greater proportion of travelers were children aged 1–5 years, visiting friends and relatives (VFR), with itineraries ≥ 30 days, and going to Africa; a smaller proportion of travelers were aged > 55 years, or traveling to Southeast Asia or the Western Pacific. During COVID-19, fewer vaccine-eligible travelers received vaccines at the pretravel consultation except for yellow fever, and a greater proportion were referred to another provider for vaccination (Figure). Table. Demographics and travel-related characteristics of international travelers seeking pretravel consultation at Global TravEpiNet sites before and during the COVID-19 pandemic Table continued. Demographics and travel-related characteristics of international travelers seeking pretravel consultation at Global TravEpiNet sites before and during the COVID-19 pandemic Figure. Vaccinations and reasons for nonvaccination among vaccine-eligible international travelers at pretravel consultations at Global TravEpiNet (GTEN) sites before and during the COVID-19 pandemic. Among vaccine-eligible travelers, we summarized those who were vaccinated at the visit (blue) and not vaccinated (orange). We then categorized reasons for nonvaccination into: provider decision (solid), referral to another provider (dots), traveler refusal (striped), or other (hatched). COVID-19 vaccination was not available at GTEN sites during the analysis period; although COVID-19 vaccinations outside of GTEN sites might have affected vaccination recommendations, they were unlikely to have had a large effect given their limited availability in January-March 2021.ConclusionCompared with pre-COVID-19, US travelers seeking pretravel consultations at GTEN sites during the pandemic might be at higher risk for travel-related infections given VFR status, traveling for ≥ 30 days, and going to Africa. Fewer vaccine-eligible travelers were vaccinated at pretravel consultations, which could reflect more virtual pretravel consultations. Counseling and vaccination for international travelers continue to be priorities during the COVID-19 pandemic.Disclosures All Authors: No reported disclosures

739. Self-Reported Prevalence of Insect Bites During International Travel

BackgroundVector borne diseases are responsible for almost one fifth of global infectious disease burden. International travelers are at risk for potentially life-threatening conditions when visiting areas with endemic vector borne disease, but this risk can be mitigated when proper insect precautions are taken. This study sought to evaluate the prevalence of insect precaution use and subsequent insect bites among Utah travelers who have attended pre-travel consultations. MethodsA cross-sectional study at the University of Utah and Salt Lake County travel clinics was analyzed. Descriptive statistics and multivariable logistic regression were used to explore factors associated with insect repellant use, and reporting bug bites despite insect repellant use.ResultsA total of 463 individuals completed the survey and were included in our analytic sample. The majority of respondents (80%) reported using insect repellent, and close to half (45%) reported bug bites. Insect repellent use was positively associated with visiting rural/countryside (OR 2.78, 95% CI 1.50 – 5.15), and traveling to South East Asia (OR 3.16, 95% CI 1.40 – 7.26), or Americas regions (OR 3.34, 95% CI 1.45 – 7.92). Being of male gender (OR 0.37, 95% CI 0.21 – 0.64) or traveling to high altitude locations (OR 0.37, 95% CI 0.18 – 0.74) was negatively associated with using insect repellent. Longer trip duration (OR 1.01, 95% CI 1.00 – 1.02) was positively associated with reporting insect bites, while male gender (OR 0.51, 95% CI 0.33 – 0.80), older age (OR 0.96, 95% CI 0.95 – 0.98), and having an advanced degree (OR 0.47, 95% CI 0.22 – 0.99) were negatively associated.Estimated Risk Factors of Insect Bites and Insect Repellent Use Characteristics of international travelers were self-reported in a cross-sectional study. Use of insect repellent and reporting bug bites despite repellant use was examined through multivariate logistic regression and used to calculate odds ratios and 95% confidence intervals. Due to multicollinearity and data skewness, the following variables were omitted from the insect repellent model: Accommodation: Hotel/other enclosed structure, Location: European, Location: and Western Pacific. Reference categories are Gender: Female, Education: High school diploma/GED or less, Group size: 1 (Traveled alone), Location type: Urban, and Malaria region: No. All other categories are not mutually exclusive and evaluated as separate binary variables.ConclusionWe show that gender, age, trip duration, and education level were associated with self-reported bug bites during travel abroad. Given the number of vector-borne diseases affecting health of travelers, our findings will contribute towards strategies to advise travelers for disease prevention.Disclosures All Authors: No reported disclosures

Etiology and outcome of febrile children coming from the tropics

IntroductionInternational travelers have grown significantly over last years, as well as imported diseases from tropical areas. Information in pediatric population is scarce. We describe demographic and clinical characteristics of febrile children coming from the tropics. MethodsRetrospective review of patients under 18 years old, presenting at a tertiary hospital and surrounding primary health care centers between July 2002 and July 2018 with a stay in a tropical region during the previous year. Patients were selected from microbiological charts of thick smears for malaria or dengue serologies. Results188 patients were studied: 52.7% were born in Spain with a median age of 3.0 years old (IQR 1.5–8.0). Main regions of stay were Sub-Saharan Africa (54.8%) and Latin America (29.8%), mostly for visiting their friends and relatives (56.3%), followed by recent arrival migrants (32.4%). Only 34% of travelers attended pre-travel consultation. More than 80% of these febrile children attended directly the Emergency Room. The most frequent diagnoses were febrile syndrome without source (56.4%), respiratory condition (15.4%) and acute diarrhea (11.7%). Around a half (52.1%) were managed as outpatients, but 46.2% were hospitalized and 7.4% were admitted to Intensive Care Unit. No specific diagnosis was achieved in 24% of cases. However, 29.7% were diagnosed with malaria. ConclusionChildren with fever coming from tropical areas were at risk of severe infectious diseases. Malaria was diagnosed in one out of four and 7% required admission in PICU. This information emphasizes the need of reinforcing training about tropical diseases among first line physicians.
