Health inequities and marginalized groups: An overview for college student travelers and travel health professionals.

One of the main goals of college- and university-sponsored travel is to broaden the global perspectives of student travelers, thereby enhancing their ability to effectively communicate and work with people from different cultural backgrounds. Pre-travel consultations are important for all students traveling internationally, and especially for those facing current or past health inequities and marginalization. To offer high quality, inclusive services, college travel health clinicians must understand both the student traveler population and cultural norms at the travel destinations, especially those related to health and safety. This article provides an overview of health equity definitions and pre-travel preparation through an equity lens. It also reviews travel health equity-related clinical implications including: helping to prepare student travelers for issues related to gender, sexuality, identity, and sexual assault; assisting travelers with preexisting health conditions and disabilities; and serving older student travelers and travelers with financial limitations.

Building Interest in the Primary Care Specialty Through Enhanced Global Health Experience.

Background An overwhelming majority of matriculating medical students in the USA are keen to deliver quality health care to all people, including the socioeconomically disadvantaged populations in remote, resource-scarce regions nationally and worldwide. Here, we describe a protocol developed to evaluate the interest of our medical students in global health activities. We also examined the relationship between students' interest in global health and readiness to pursue a future career in the primary care specialty. Materials and methods We designed a survey in Qualtrics online software and reached all first-year and third-year medical students between 2019 and 2022 enrolled at the Alabama College of Osteopathic Medicine (ACOM). The survey utilized ordinal scale items to explore the medical students' interest in primary care residency programs, their interest in global health and international travel, and their perceptions of how a range of factors might motivate their desire to participate in global health activities. The study was approved by ACOM's Institutional Review Board (IRB). In order to compare findings from this study with data from other medical schools, we developed constructs using the national aggregate data, in percentages, from matriculants and graduates of Doctor of Osteopathic Medicine (DO) degree-granting medical schools according to gender, published by the American Association of Colleges of Osteopathic Medicine (AACOM). Statistical analysis of national aggregate data was performed using the unpaired t-test. Results Both female and male participants had lived or traveled abroad before starting medical school. Female (98%, n=249) and male (95%, n=140) participants in the first-year cohorts considered helping the underserved population as important or very important as it is related to a career in medicine. Females in the third-year cohorts (97%, n=71) also ranked this statement as important or very important compared to male cohorts (89%, n=31). A higher proportion of females (43%, n=108) compared to males (35%, n=52) in first-year cohorts agreed or strongly agreed that they would likely pursue a residency in primary care. More females (59%, n=43) than males (46%, n=16) in the third-year cohorts agreed or strongly agreed with the same statement. Analysis of the aggregate national data (2009-2022) revealed that the percentage (actual count not available) of female students who planned to practice in underserved/shortage area was higher both at the time of matriculation (M=51%, SD=4%) and before graduation (M=40%, SD=4%) compared to males (matriculation: M=40%, SD=5%; graduation: M=33%, SD=4%) presenting a significant difference (matriculation t(24)=6.7, p<0.0001; graduation t(24)=5.4, p<0.0001). Furthermore, a higher percentage of females at the time of matriculation (M=25%, SD=5%) and graduation (M=40%, SD=6%) planned to practice in the primary care specialties compared to males (matriculation: M=17%, SD=4%; graduation: M=29%, SD=6%) presenting a significant difference (matriculation: t(24)=4.6, p = 0.0001; graduation: t(24)=4.8, p<0.0001). Conclusions Interest in global health activities may be associated with interest in pursuing a future career in the primary care specialty. In this study, more female medical students expressed interest in participating in global health experiences, serving the underserved population domestically and abroad, and expressing interest in primary care than males.

The Clinical and Economic Impact of Measles-Mumps-Rubella Vaccinations to Prevent Measles Importations From US Pediatric Travelers Returning From Abroad.

BACKGROUND: Pediatric international travelers account for nearly half of measles importations in the United States. Over one third of pediatric international travelers depart the United States without the recommended measles-mumps-rubella (MMR) vaccinations: 2 doses for travelers ≥12 months and 1 dose for travelers 6 to <12 months. METHODS: We developed a model to compare 2 strategies among a simulated cohort of international travelers (6 months to <6 years): (1) No pretravel health encounter (PHE): travelers depart with baseline MMR vaccination status; (2) PHE: MMR-eligible travelers are offered vaccination. All pediatric travelers experience a destination-specific risk of measles exposure (mean, 30 exposures/million travelers). If exposed to measles, travelers' age and MMR vaccination status determine the risk of infection (range, 3%-90%). We included costs of medical care, contact tracing, and lost wages from the societal perspective. We varied inputs in sensitivity analyses. Model outcomes included projected measles cases, costs, and incremental cost-effectiveness ratios ($/quality-adjusted life year [QALY], cost-effectiveness threshold ≤$100 000/QALY). RESULTS: Compared with no PHE, PHE would avert 57 measles cases at $9.2 million/QALY among infant travelers and 7 measles cases at $15.0 million/QALY among preschool-aged travelers. Clinical benefits of PHE would be greatest for infants but cost-effective only for travelers to destinations with higher risk for measles exposure (ie, ≥160 exposures/million travelers) or if more US-acquired cases resulted from an infected traveler, such as in communities with limited MMR coverage. CONCLUSIONS: Pretravel MMR vaccination provides the greatest clinical benefit for infant travelers and can be cost-effective before travel to destinations with high risk for measles exposure or from communities with low MMR vaccination coverage.

Underestimation of travel-associated risks by adult and paediatric travellers compared to expert assessment: A cross-sectional study at a hospital-based family pre-travel clinic.

BACKGROUND: Travellers' perception of their risk for acquiring travel-related conditions is an important contributor to decisions and behaviors during travel. In this study, we aimed to assess the differences between traveller-perceived and expert-assessed risk of travel-related conditions in children and adults travelling internationally and describe factors that influence travellers' perception of risk. METHODS: Children and adults were recruited at the Hospital for Sick Children's Family Travel Clinic between October 2014 and July 2015. A questionnaire was administered to participants to assess their perceived risk of acquiring 32 travel-related conditions using a 7-point Likert scale. Conditions were categorized as vector-borne diseases, vaccine-preventable diseases, food and water borne diseases, sexually transmitted infections and other conditions. Two certified travel medicine experts reviewed each patient's chart and assigned a risk score based on the same 7-point Likert scale. Traveller and expert risk scores were compared using paired t-tests. RESULTS: In total, 207 participants were enrolled to participate in this study, 97 children (self-reported, n = 8; parent-reported, n = 89), and 110 adults. Travel-related risk for adults and parents answering for their children were significantly underestimated when compared to expert-assessed risk for 26 of the 32 assessed conditions. The underestimated conditions were the same for both adults and parents answering for children. Travel-related risk was not over-estimated for any condition. CONCLUSIONS: Adults underestimated their children's and their own risk for most travel-related conditions. Strategies to improve the accuracy of risk perception of travel-related conditions by travellers are needed to optimize healthy travel for children and their families.

[Argentine Presidential Medical Unit. Survey of the Argentine hospital network and resources for golden hour pathologies.] / Unidad Médica Presidencial Argentina. Relevamiento de la red hospitalaria Argentina y recursos para patologías de hora de oro.

Introduction: Presidential medical units are intended to protect the dignitary's health in multiple aspects and work in close relationship with security. There are three central areas of coverage: myocardial infarction, stroke and trauma. By 2016 we had not found information about the resources on medical centers in Argentina and their integration into healthcare networks. Objective: Describe the relevant medical centers and their available resources for the medical coverage areas mentioned. Methods: It is a descriptive, cross-sectional study between 12/2016 and 8/2019. The sampling was not probabilistic and for convenience. Variables were reported as proportions and comparisons were made using the chi-square test or Fischer. Results: 232 centers were entered, 66.8% in capital cities and 67% in the public sector. Capitals were associated with a greater presence of resources: category 3 centers (OR 7.85; 95% CI 3.66-16.84; p <0.000001), angiography (OR 5.94; 95% CI 3.24-10.28; p <0.000001 ), tomography (OR 3.41; 95% CI 1.51-7.69; p=0.002), thrombolytics (OR 3.24; 95% CI 1.37-7.76; p=0.005); except trauma surgery (OR 1.83; 95% CI 0.75-4.46; p=0.17). Private centers were associated with greater resources for reperfusion; and public centers for trauma treatment. Conclusions: There is an unbalanced distribution of key resources between capital and non-capital cities in large geographical areas that makes it impossible to develop an adequate network for the treatment of heart attack, stroke and trauma. The best quality of care requires combining public and private networks.

Introducción: Las unidades médicas presidenciales están destinadas a proteger la salud del dignatario en múltiples aspectos y en íntima relación con la seguridad. Existen tres áreas centrales de cobertura: el infarto de miocardio, el accidente cerebrovascular y trauma. Hacia el año 2016 no hemos hallado información sobre los recursos de los centros médicos en Argentina y su integración en redes de atención. Objetivo: Describir los centros médicos relevados y sus recursos para las áreas médicas de cobertura mencionadas. Métodos: Es un estudio descriptivo, de corte trasversal entre 12/2016 y 8/2019. El muestreo fue no probabilístico y por conveniencia. Las variables se reportaron como proporciones y las comparaciones se realizaron mediante el test de chi cuadrado o Fischer. Resultados: Ingresaron 232 centros, 66.8% en ciudades capitales y 67% del ámbito público. Las capitales se asociaron con mayor presencia de recursos: centros categoría 3 (OR 7.85; IC del 95% 3.66-16.84; p<0,000001), angiografía (OR 5.94; IC del 95% 3.24-10.28; p<0,000001), tomografía (OR 3.41; IC del 95% 1.51-7.69; p=0,002), trombolíticos (OR 3.24; IC del 95% 1.37-7.76; p=0,005); excepto cirugía de trauma (OR 1.83; IC del 95% 0.75-4.46; p=0,17). Los centros privados se asociaron con mayores recursos para la reperfusión; y los centros públicos para el tratamiento del trauma. Conclusiones: Se observa una desbalanceada distribución de recursos claves entre ciudades capitales y no capitales en extensas áreas geográficas que imposibilita el desarrollo de una adecuada red para el tratamiento del infarto, accidente cerebrovascular y trauma. La mejor calidad de atención requiere combinar redes públicas y privadas.

Spatial and temporal variation of dengue incidence in the island of Bali, Indonesia: An ecological study.

BACKGROUND: Dengue fever control in the tropical island of Bali in Indonesia carries important significance both nationally and globally, as it is one of the most endemic islands in Indonesia and a worldwide popular travel destination. Despite its importance, the spatial and temporal heterogeneity in dengue risk and factors associated with its variation in risk across the island has not been not well explored. This study was aimed to analyze for the first time the geographical and temporal patterns of the incidence of dengue and to quantify the role of environmental and social factors on the spatial heterogeneity of dengue incidence in Bali. METHODS: We analyzed retrospective dengue notification data at the sub-district level (Kecamatan) from January 2012 to December 2017 which obtained from the Indonesian Ministry of Health. Seasonality in notified dengue incidence was assessed by seasonal trend decomposition analysis with Loess (STL) smoothing. Crude standardized morbidity rates (SMRs) of dengue were calculated. Moran's I and local indicators of spatial autocorrelation (LISA) analysis were employed to assess spatial clustering and high-risk areas over the period studied. Bayesian spatial and temporal conditional autoregressive (CAR) modeling was performed to quantify the effects of rainfall, temperature, elevation, and population density on the spatial distribution of risk of dengue in Bali. RESULTS: Strong seasonality of dengue incidence was observed with most cases notified during January to May. Dengue incidence was spatially clustered during the period studied with high-risk kecamatans concentrated in the south of the island, but since 2014, the high-risk areas expanded toward the eastern part of the island. The best-fitted CAR model showed increased dengue risk in kecamatans with high total annual rainfall (relative risk (RR): 1.16 for each 1-mm increase in rainfall; 95% Credible interval (CrI): 1.03-1.31) and high population density (RR: 7.90 per 1000 people/sq.km increase; 95% CrI: 3.01-20.40). The RR of dengue was decreased in kecamatans with higher elevation (RR: 0.73 for each 1-m increase in elevation; 95% CrI: 0.55-0.98). No significant association was observed between dengue RR and year except in 2014, where the dengue RR was significantly lower (RR: 0.53; 95% CrI: 0.30-0.92) relative to 2012. CONCLUSIONS: Dengue incidence was strongly seasonal and spatially clustered in Bali. High-risk areas were spread from kecamatans in Badung and Denpasar toward Karangasem and Klungkung. The spatial heterogeneity of dengue risk across Bali was influenced by rainfall, elevation, and population density. Surveillance and targeted intervention strategies should be prioritized in the high-risk kecamatans identified in this study to better control dengue transmission in this most touristic island in Indonesia. Local health authorities should recommend travelers to use personal protective measures, especially during the peak epidemic period, before visiting Bali.

Disparities in hepatitis A virus (HAV) vaccination coverage among adult travelers to intermediate or high-risk countries: The role of birthplace and race/ethnicity.

BACKGROUND: While the hepatitis A virus (HAV) vaccine is recommended for United States (US) travelers to endemic regions, vaccination rates are lower among non-US-born adults and some racial minority groups. PURPOSE: We aimed to examine the relationship between birthplace, race and their interaction as predictors of self-reported HAV vaccination among adult travelers to high-risk countries (HRCs) through analysis of the National Health Interview Survey (NHIS), 2012-2015. METHODS: The study included 36,872 US adult participants in the 2012-2015 NHIS who traveled to countries where HAV is endemic. The main outcome was self-reported HAV vaccination (≥2 doses). Complex survey methods were applied to all models to provide statistical estimates that were representative of US adults. Multivariable logistic regression models adjusting for demographic, socioeconomic, medical, and access-to-care characteristics were fitted to examine the association between birthplace, race, race-by-birthplace (for interaction) and vaccination status. RESULTS: For adult travelers to HRCs, the adjusted odds ratio (AOR) of HAV vaccination was lower for non-US-born compared to US-born adults, AOR 0.86 (95% CI; 0.76, 0.98). For Hispanics, the AOR of HAV vaccination was 0.80 (95% CI; 0.70, 0.91) as compared to non-Hispanic-Whites. Furthermore, a significant qualitative interaction between birthplace and race was found (P-value 0.0005). Among non-Hispanic Blacks, the adjusted odds of HAV vaccination for non-US-born adults were 1.35 (95% CI; 1.06, 1.72) times the odds for US-born adults. In contrast, the AORs of HAV vaccination of non-US-born versus US-born adults were 36% (95% CI; 17%, 51%) and 30% (95% CI; 12%, 44%), lower for Asians and Hispanics, respectively. CONCLUSIONS: The association between birthplace and HAV vaccination status differs by race among travelers to HRCs, with US-born non-Hispanic Black and non-US-born Asian and Hispanic adults having lower odds of vaccination. Health care resources should be focused on these target populations to improve travel vaccination compliance.

Burden of typhoid fever and cholera: similarities and differences. Prevention strategies for European travelers to endemic/epidemic areas.

The burden of diarrheal diseases is very high, accounting for 1.7 to 5 billion cases per year worldwide. Typhoid fever (TF) and cholera are potentially life-threatening infectious diseases, and are mainly transmitted through the consumption of food, drink or water that have been contaminated by the feces or urine of subjects excreting the pathogen. TF is mainly caused by Salmonella typhi, whereas cholera is caused by intestinal infection by the toxin-producing bacterium Vibrio cholerae. These diseases typically affect low- and middle-income countries where housing is overcrowded and water and sanitation are poor, or where conflicts or natural disasters have led to the collapse of the water, sanitation and healthcare systems. Mortality is higher in children under 5 years of age. Regarding their geographical distribution, TF has a high incidence in sub-Saharan Africa, India and south-east Asia, while cholera has a high incidence in a few African countries, particularly in the Horn of Africa and the Arabian Peninsula. In the fight against these diseases, preventive measures are fundamental. With modern air travel, transmissible diseases can spread across continents and oceans in a few days, constituting a threat to global public health. Nowadays, people travel for many reasons, such as tourism and business. Several surveys have shown that a high proportion of travelers lack adequate information on safety issues, such as timely vaccination and prophylactic medications. The main objective of this overview is to provide information to help European travelers to stay healthy while abroad, and thus also to reduce the potential importation of these diseases and their consequent implications for public health and society. The preventive measures to be implemented in the case of travel to countries where these diseases are still endemic are well known: the adoption of safe practices and vaccinations. It is important to stress that an effective preventive strategy should be based both on vaccinations and on hygiene travel guidelines. Furthermore, the emergence of multidrug-resistant strains is becoming a serious problem in the clinical treatment of these diseases. For this reason, vaccination is the main solution.

Attitudes and awareness of medical assistance while traveling abroad.

BACKGROUND: With globalization, more and more people travel to countries where they are at risk of injuries and travel-related diseases. To protect travelers' health, it is crucial to understand whether travelers accurately perceive medical assistance resources before and during their trips. This study investigated the need, awareness, and previous usage of overseas emergency medical assistance services (EMAS) among people traveling abroad. METHODS: Anonymous questionnaires were distributed to patients (n = 500) at a travel clinic in Taipei, Taiwan. RESULTS: The results showed that EMAS were important, especially in the following categories: 24-h telephone medical consultation (91.8%), emergent medical repatriation (87.6%), and assistance with arranging hospital admission (87.4%). Patients were less aware of the following services: arrangement of appointments with doctors (70.7%) and monitoring of medical conditions during hospitalization (73.0%). Less than 5% of respondents had a previous experience with EMAS. CONCLUSIONS: EMAS are considered important to people who are traveling abroad. However, approximately 20-30% of travelers lack an awareness of EMAS, and the percentage of travelers who have previously received medical assistance through these services is extremely low. The discrepancy between the need and usage of EMAS emphasizes the necessity to adapt EMAS materials in pre-travel consultations to meet the needs of international travelers.

Knowledge, attitudes, and practices regarding travel health among Muscat International Airport travelers in Oman: Identifying the gaps and addressing the challenges.

Although the majority of travel-associated communicable diseases can be prevented, the public health burden of these diseases remains significant. Relatively little is known about how travelers know and perceive the health risks associated with travel and how they utilize preventive measures before and while traveling abroad. This study was conducted to determine the level of the knowledge, attitudes, and practices (KAP) of Muscat International Airport travelers about travel health in order to assess the knowledge gap and the need for travel health services in Oman. A cross-sectional study was conducted over a period of 1week using a self-administered questionnaire. The overall level of knowledge about vaccine-preventable diseases, food safety, and preventive measures against insect bites of the participants was inadequate. The practice concerning preventive travel health measures, such as the use of specific immunizations and antimalarial prophylaxis, was very limited, and influenced by some personal and travel-related factors. The inadequate level of travelers' knowledge and poor utilization of travel medicine services highlights the need for the provisions of specialized travel medicine services at the national level and to develop educational materials promoting the importance of pre-travel health advice.

Travel and Adventure Medicine Resources.

Given the ever-changing nature of travel medicine, practitioners who provide pretravel and posttravel care are obligatorily students for the duration of their professional careers. A large variety of resources are available for medical practitioners. Providers should join at least one travel or tropical medicine professional association, attend its annual meeting, and read its journal. The largest general travel medicine association is the International Society of Travel Medicine.

[Assistance medicine, a novel discipline of emergency medicine]. / A sürgosségi ellátás új területe: az assistance orvostan.

The number of international travels has been continuously increasing since World War II. Though the travelers' demand for safer ways of travelling appeared, only a handful of them sought pretravel advices. This is the reason why 50% of the travelers have to face some kind of medical problem during their journey. If they have travel insurance, the company's assistance team organizes, monitors and covers their abroad treatment. A doctor of the assistance team has to find her/his ways in various fields: not only a multidisciplinary medical knowledge is a must for a professional like this, but she/he needs to have a good grasp of the basic idea behind the insurance policy, too. Also, she/he should be familiar with the public health care systems of different countries and some legal knowledge is also needed. If the patients are unable to continue their trip, they must be repatriated. Making a decision about the repatriation's timing and modality requires interdisciplinary medical experience and the approach of a critical care/emergency doctor. Among further tasks for the assistance team's doctor one can find medical escort and on-spot medical visit for foreign patients. Both of these two aforementioned medical activities are highly different from - for example - a general practitioner's routine. That is the reason why an assistance doctor has to be familiar with the critical and emergency care. Organizing and monitoring medical treatment for a traveler abroad, providing medical escort, making decisions about repatriation and providing medical help for a foreign patient all fall within the competence of a new medical discipline, the assistance medicine. Creating a body of knowledge, collecting appropriate protocols and establishing postgraduate courses for assistance medicine diplomas are the tasks of the critical care and emergency medicine professionals.

An overview of travel-associated central nervous system infectious diseases: risk assessment, general considerations and future directions.

Nervous system infections are among the most important diseases in travellers. Healthy travellers might be exposed to infectious agents of central nervous system, which may require in-patient care. Progressive course is not uncommon in this family of disorders and requires swift diagnosis. An overview of the available evidence in the field is, therefore, urgent to pave the way to increase the awareness of travel-medicine practitioners and highlights dark areas for future research. In November 2013, data were collected from PubMed, Scopus, and Web of Knowledge (1980 to 2013) including books, reviews, and peer-reviewed literature. Works pertained to pre-travel care, interventions, vaccinations related neurological infections were retrieved. Here we provide information on pre-travel care, vaccination, chronic nervous system disorders, and post-travel complications. Recommendations with regard to knowledge gaps, and state-of-the-art research are made. Given an increasing number of international travellers, novel dynamic ways are available for physicians to monitor spread of central nervous system infections. Newer research has made great progresses in developing newer medications, detecting the spread of infections and the public awareness. Despite an ongoing scientific discussion in the field of travel medicine, further research is required for vaccine development, state-of-the-art laboratory tests, and genetic engineering of vectors.
