Expanding travel medicine in the 21st century to address the health needs of the world's migrants

A scoping review of sexual and reproductive health recommendations in the context of migration to Europe

In recent years, growing instability and conflict around the world have continued to fuel outward migration, including migration to the EU/EEA. Many migrants hail from countries and regions with a higher burden of STIs-including HIV-and are exposed to enhanced risks of sexual and gender-based violence leading to sexual health issues during their journeys. This scoping review aims to identify existing sexual health recommendations for non-European migrants in the EU/EEA and identify gaps in their implementation. Sexual health recommendations formulated in relation to the migrant population in peer- reviewed journals or by expert consensus, between 2010 and 2021, were included. A keyword search was used to retrieve relevant publications on PubMed, ScienceDirect, the Cochrane Library databases, WHO and ECDC websites. The search strategy employed was charted in a dedicated Prisma Chart. Overall, 180 publications were retrieved. Based on the abstract and after eliminating duplicates, 33 publications were included for full-text reading. The references of these publications were screened. In total, 19 publications met the inclusion criteria. Evidence-based sexual health recommendations target only newly arrived migrants and migrant children (at arrival and during stay in the country). Screening practices are mostly informed by the country of origin and related prevalence, which remains a limitation; challenges faced during migration should also be considered. Implementation and compliance with these recommendations remain uncertain, as sexual health is not funded and addressed in a uniform manner across Europe.

Health challenges in refugee resettlement: an innovative multi-sector partnership to improve the continuum of care for resettled refugees

Refugee resettlement is a complex process relevant to migration medicine. A partnership between the International Organization for Migration, the US Centers for Disease Control and Prevention, and the University of Minnesota addresses medical needs of refugees and serves as a model for improving the continuum of care delivered to refugees.

Challenges of Managing Skin Diseases in Refugees and Migrants

"Currently, an estimated 70.8 million individuals worldwide are forcibly displaced due to war, violence, and persecution. Barriers to providing dermatologic care include the large number of affected people, their movement within and across international borders, security issues, and limited access to dermatology expertise and formularies. Screening protocols for skin diseases and sexually transmitted infections differ worldwide, raising the need for shared guidelines to assess migrants' health. This article reviews the literature of skin and sexually transmitted infections in migrants and displaced persons, highlighting the impact of social determinants on skin health and challenges faced in providing care."

The role of travel agents in travel medicine-a study with agencies from São Paulo, Brazil

A survey in São Paulo, Brazil, assessed travel agents’ knowledge on travellers’ health. Data were collected using an online questionnaire. Of 200 agencies contacted, 32 answered (34 agents). Most consultants reported discussing personal safety, health insurance and vaccination. Few provided information on water and food diseases or sexually transmitted infections.

Improving Cross-Border Preparedness and Response: Lessons Learned from 3 Lassa Fever Outbreaks Across Benin, Nigeria, and Togo, 2017-2019

Long-standing cultural, economic, and political relationships among Benin, Nigeria, and Togo contribute to the complexity of their cross-border connectivity. The associated human movement increases the risk of international spread of communicable disease. The Benin and Togo ministries of health and the Nigeria Centre for Disease Control, in collaboration with the Abidjan Lagos Corridor Organization (a 5-country intergovernmental organization) and the US Centers for Disease Control and Prevention, sought to minimize the risk of cross-border outbreaks by defining and implementing procedures for binational and multinational public health collaboration. Through 2 multinational meetings, regular district-level binational meetings, and fieldwork to characterize population movement and connectivity patterns, the countries improved cross-border public health coordination. Across 3 sequential cross-border Lassa fever outbreaks identified in Benin or Togo between February 2017 and March 2019, the 3 countries improved their collection and sharing of patients' cross-border travel histories, shortened the time between case identification and cross-border information sharing, and streamlined multinational coordination during response efforts. Notably, they refined collaborative efforts using lessons learned from the January to March 2018 Benin outbreak, which had a 100% case fatality rate among the 5 laboratory-confirmed cases, 3 of whom migrated from Nigeria across porous borders when ill. Aligning countries' expectations for sharing public health information would assist in reducing the international spread of communicable diseases by facilitating coordinated preparedness and responses strategies. Additionally, these binational and multinational strategies could be made more effective by tailoring them to the unique cultural connections and population movement patterns in the region.

Migration Health: Highlights from Inaugural International Society of Travel Medicine (ISTM) Conference on Migration Health

PURPOSE OF REVIEW

International migration is a global phenomenon that is growing in scope, complexity and impact. The inaugural International Society of Travel Medicine (ISTM) International Conference on Migration Health provided a forum to discuss scientific evidence on the broad issues relevant to migration health. This review summarises the key health issues, with a focus on infectious diseases, current effective strategies and future considerations presented at this forum and in the recent literature.

RECENT FINDINGS

Migrants face health disparities for both communicable and non-communicable diseases. Their heightened infectious disease risks, compared to host populations, are related to pre-migration exposures, the circumstances of the migration journey and the receptivity and access to health services in their receiving countries. While the prevalence of infectious diseases identified through screening programmes are generally low, delays in diagnosis and treatment for a range of treatable infectious diseases result in higher morbidity and mortality among migrants. Barriers to care in host countries occur at the patient, provider and health systems levels. Coordinated and inclusive health services, healthcare systems and health policies, responsive to patient diversity reduce these barriers. Structural barriers to healthcare provision impede equitable care to migrants and refugees. Public health and medical professionals have a role in advocating for policy reforms.

Insights into needs of business travelers to China from calls to a medical assistance provider

Background

Although 17.5% of German travelers were business travelers in the years 2011–2013, little is known about their pathologies. Recent publications indicate that infections are the primary health issue in general travelers. Our aim was to investigate whether business travelers from Germany to China also primarily suffer from infections.

Methods

From 2011 to 2013, 587 calls for service of German business travelers to China were collected by a medical assistance provider. 482 of these calls were evaluated regarding demographics, reported diseases and conditions and the type of service provided by the medical assistance company.

Results

The most common reasons for calls for service were “factors influencing health status and contact with health service” (18.8%), “injury and poisoning” (16.0%) as well as “symptoms, signs, and ill-defined conditions” (13.7%). Most patients asked for “medical advice” (37.8%), referral to “outpatient care” (25.1%) or “inpatient care” (16.6%). “Evacuation and/or repatriation” was required mainly due to “injury and poisoning” (n = 12), “diseases of the circulatory system” (n = 5) or “mental disorders” (n = 3).

Conclusion

German business travelers to China are seeking primarily administrative support from a medical assistance provider and are mostly affected by non-infectious diseases. Pre-travel preparation of such travelers need to place more emphasis on non-communicable health risks and prevention.

Reducing infectious disease inequities among migrants

BACKGROUND

migration has reached unprecedented levels, with 3.6% of the world's population living outside their country of birth. Migrants comprise a substantial proportion of high-income country populations, are at increased risk of a range of infectious diseases, compared to native-born populations and may experience worse health outcomes due to barriers accessing timely diagnoses and treatment. Poor access to essential healthcare services can be attributed to several factors, including language and cultural barriers and lack of specific inclusive health policies.

METHODS

This review draws on evidence from the immigrant health and travel medicine literature, with a focus on infectious disease risks. It presents strategies to reduce barriers to healthcare access through health promotion and screening programs both at the community and clinic level and the delivery of linguistically and culturally competent care. The Methods: Salud Entre Culturas (SEC) 'Health Between Cultures' project from the Tropical Medicine Unit at the Hospital Ramon y Cajal in Madrid is described as an effective model of care.

RESULTS

For those providing healthcare to migrant populations, the use of community-consulted approaches are considered best practice in the development of health education, health promotion and the delivery of targeted health services. At the clinic-level, strategies optimizing care for migrants include the use of bilingual healthcare professionals or community-based healthcare workers, cultural competence training of all clinic staff, the appropriate use of trained interpreters and the use of culturally appropriate health promotion materials.

CONCLUSIONS

Multifaceted strategies are needed to improve access, community knowledge, community engagement and healthcare provider training to provide appropriate care to migrant populations to reduce infectious disease disparities.

Mental health needs and services for migrants: an overview for primary care providers

BACKGROUND

The objective of this article is to present an overview of the burden, spectrum of diseases and risk factors for mental illness among subgroups of migrants, namely, immigrants, refugees and individuals with precarious legal status. This expert review summarises some of the implications for primary care services in migrant receiving countries in the global North.

METHODS

A broad literature review was conducted on the epidemiology of mental health disorders in migrants and the available evidence on mental health services for this population focusing on key issues for primary care practitioners in high-income countries.

RESULTS

Although most migrants are resilient, migration is associated with an over-representation of mental disorder in specific subpopulations. There is a general consensus that stress-related disorders are more prevalent among refugee populations of all ages compared to the general population. Relative to refugees, migrants with precarious legal status may be at even higher risk of depression and anxiety disorders. Persistence and severity of psychiatric disorders among migrant populations can be attributed to a combination of factors including severity of trauma exposures during the migration process. Exposure to stressors after resettlement, such as poverty and limited social support, also impacts mental illness. Services for migrants are affected by restricted accessibility and should address cultural and linguistic barriers to and issues in the larger social environment that impact psychosocial functioning.

CONCLUSION

There is substantial burden of mental illness among some migrant populations. Primary care providers seeking to assist individuals need to be cognizant of language barriers to and challenges of working with interpreters as well as sensitive to cultural and social contexts within the diagnosis and service delivery process. In addition, best practices in screening migrants and providing intervention services for mental disorders need to be sensitive to where individuals and families are in the resettlement trajectory.

Spectrum of illness in migrants to Canada: sentinel surveillance through CanTravNet

BACKGROUND

Due to ongoing political instability and conflict in many parts of the world, migrants are increasingly seeking asylum and refuge in Canada.

METHODS

We examined demographic and travel correlates of illnesses among migrants to Canada to establish a detailed epidemiologic framework of this population for Canadian practitioners. Data on ill-returned Canadian travellers presenting to a CanTravNet site between 1 January 2015 and 31 December 2015 were analyzed.

RESULTS

During the study period, 2415 ill travellers and migrants presented to a CanTravNet site, and of those, 519 (21.5%) travelled for the purpose of migration. Sub-Saharan Africa (n = 160, 30.8%), southeast Asia (n = 84, 16.2%) and south central Asia (n = 75, 14.5%) were the most common source regions for migrants, while the top specific source countries, of 98 represented, were the Philippines (n = 45, 8.7%), China (n = 36, 6.9%) and Vietnam (n = 31, 6.0%). Compared with non-migrant travellers, migrants were more likely to have a pre-existing immunocompromising medical condition, such as HIV or diabetes mellitus (P < 0.0001), and to require inpatient management of their illness (P < 0.0001). Diagnoses such as tuberculosis (n = 263, 50.7%), hepatitis B and C (n = 78, 15%) and HIV (n = 11, 2.1%) were over-represented in the migrant population compared with non-migrant travellers (P < 0.0001). Most cases of tuberculosis in the migrant population (n = 263) were latent (82% [n = 216]); only 18% (n = 47) were active.

CONCLUSIONS

Compared with non-migrant travellers, migrants were more likely to present with a communicable infectious disease, such as tuberculosis, potentially complicated by an underlying immunosuppressing condition such as HIV. These differences highlight the divergent healthcare needs in the migrant population, and underscore the importance of surveillance programmes to understand their burden of illness. Intake programming should be adequately resourced to accommodate the medical needs of this vulnerable population of new Canadians.
