Is There a Risk of Yellow Fever Virus Transmission in South Asian Countries with Hyperendemic Dengue?

The fact that yellow fever (YF) has never occurred in Asia remains an "unsolved mystery" in global health. Most countries in Asia with high Aedes aegypti mosquito density are considered "receptive" for YF transmission. Recently, health officials in Sri Lanka issued a public health alert on the potential spread of YF from a migrant group from West Africa. We performed an extensive review of literature pertaining to the risk of YF in Sri Lanka/South Asian region to understand the probability of actual risk and assist health authorities to form evidence informed public health policies/practices. Published data from epidemiological, historical, biological, molecular, and mathematical models were harnessed to assess the risk of YF in Asia. Using this data we examine a number of theories proposed to explain lack of YF in Asia. Considering the evidence available, we conclude that the probable risk of local transmission of YF is extremely low in Sri Lanka and for other South Asian countries despite a high Aedes aegypti density and associated dengue burden. This does not however exclude the future possibility of transmission in Asia, especially considering the rapid influx travelers from endemic areas, as we report, arriving in Sri Lanka

Health status of returning refugees, internally displaced persons, and the host community in a post-conflict district in northern Sri Lanka: a cross-sectional survey.

BACKGROUND: Although the adverse impacts of conflict-driven displacement on health are well-documented, less is known about how health status and associated risk factors differ according to displacement experience. This study quantifies health status and quality of life among returning refugees, internally displaced persons, and the host community in a post-conflict district in Northern Sri Lanka, and explores associated risk factors. METHODS: We analysed data collected through a household survey (n = 570) in Vavuniya district, Sri Lanka. The effect of displacement status and other risk factors on perceived quality of life as estimated from the 36-item Short Form Questionnaire, mental health status from 9-item Patient Health Questionnaire, and self-reported chronic disease status were examined using univariable analyses and multivariable regressions. RESULTS: We found strong evidence that perceived quality of life was significantly lower for internally displaced persons than for the host community and returning refugees, after adjusting for covariates. Both mental health status and chronic disease status did not vary remarkably among the groups, suggesting that other risk factors might be more important determinants of these outcomes. CONCLUSIONS: Our study provides important insights into the overall health and well-being of the different displaced sub-populations in a post-conflict setting. Findings reinforce existing evidence on the relationship between displacement and health but also highlight gaps in research on the long-term health effects of prolonged displacement. Understanding the heterogeneity of conflict-affected populations has important implications for effective and equitable humanitarian service delivery in a post-conflict setting

Missing: Where Are the Migrants in Pandemic Influenza Preparedness Plans?

Influenza pandemics are perennial global health security threats, with novel and seasonal influenza affecting a large proportion of the world’s population, causing enormous economic and social destruction. Novel viruses such as influenza A(H7N9) continue to emerge, posing zoonotic and potential pandemic threats. Many countries have developed pandemic influenza preparedness plans (PIPPs) aimed at guiding actions and investments to respond to such outbreak events. Migrant and mobile population groups—such as migrant workers, cross-border frontier workers, refugees, asylum seekers, and other non-citizen categories residing within national boundaries—may be disproportionately affected in the event of health emergencies, with irregular/undocumented migrants experiencing even greater vulnerabilities. Because of a combination of political, sociocultural, economic, and legal barriers, many migrants have limited access to and awareness of health and welfare services, as well as their legal rights. The conditions in which migrants travel, live, and work often carry exceptional risks to their physical and mental well-being. Even if certain migrant groups have access to health services, they tend to avoid them due to fear of deportation, xenophobic and discriminatory attitudes within society, and other linguistic, cultural, and economic barriers. Evidence indicates that social stigmatization and anxieties generated by restrictive immigration policies hinder undocumented immigrants’ access to health rights and minimizes immigrants’ sense of entitlement to such rights

Migration health research and policy in south and south-east Asia: mapping the gaps and advancing a collaborative agenda

Migrant health has been the subject of various international agreements in recent years. In parallel, there has been a growth in academic research in this area. However, this increase in focus at international level has not necessarily strengthened the capacity to drive evidence-informed national policy and action in many low- and middle-income countries. The Migration Health South Asia (MiHSA) network aims to challenge some of the barriers to progress in the region. Examples include the bias towards institutions in high-income countries for research funding and agenda-setting and the overall lack of policy-focused research in the region. MiHSA will engage researchers, funders and policy-makers in collectively identifying the most pressing, yet feasible, research questions that could help strengthen migrant and refugee health relevant to the region’s national contexts. In addition, policies and provisions for different migrant populations in the region will be reviewed from the health and rights perspectives, to identify opportunities to strategically align research agendas with the questions being asked by policy-makers. The convergence of migration policy with other areas such as health and labour at global level has created a growing imperative for policy-makers in the region to engage in cross-sector dialogue to align priorities and coordinate responses. Such responses must go beyond narrow public health interventions and embrace rights-based approaches to address the complex patterns of migration in the region, as well as migrants’ precarity, vulnerabilities and agency

Bridging the gap: Using CHNRI to align migration health research priorities in India with local expertise and global perspectives.

Background Migration and health are increasingly recognised as a global public health priority, but concerns have been raised on the skewed nature of current research and the potential disconnect between health needs and policy and governance responses. The Migration Health South Asia (MiHSA) network led the first systematic research priority-setting exercise for India, aligned with the global call to develop a clearly defined migration health research agenda that will inform research investments and guide migrant-responsive policies by the year 2030. Methods We adapted the Child Health and Nutrition Research Initiative (CHNRI) method for this priority setting exercise for migration health. Guided by advisory groups established at international and country levels, we sought research topics from 51 experts from diverse disciplines and sectors across India. We consolidated 223 responses into 59 research topics across five themes and scored them against five predefined criteria: answerability, effectiveness, feasibility, impact, and effect on equity. We then calculated research priority scores (RPS) and average expert agreement (AEA) each research topic and theme. Results A third of the 59 research topics were on migrants' health and health care access, 12 on social determinants of migrants' health, 10 on policies, law and migration health governance, eight on health systems' responsiveness, and five on migration health discourse. Three of the top five priority topics pertained to migrants' health care access. The policies, law, and governance theme had the highest overall RPS score. Conclusions There is a noticeable gap between research priorities identified by experts at the country-level and the current research focus and priorities set globally. This disconnect between the global and local perspectives in migration health scholarship hinders the development of context-specific and suitable policy agendas for improving migrants' health. Our co-developed agenda emphasises the need to prioritise research on the capacity of existing systems and policies so as to make them more migration-aware and responsive to migrants' health needs

Bibliometric analysis of global migration health research in peer-reviewed literature (2000-2016).

BACKGROUND: The health of migrants has become an important issue in global health and foreign policy. Assessing the current status of research activity and identifying gaps in global migration health (GMH) is an important step in mapping the evidence-base and on advocating health needs of migrants and mobile populations. The aim of this study was to analyze globally published peer-reviewed literature in GMH. METHODS: A bibliometric analysis methodology was used. The Scopus database was used to retrieve documents in peer-reviewed journals in GMH for the study period from 2000 to 2016. A group of experts in GMH developed the needed keywords and validated the final search strategy. RESULTS: The number of retrieved documents was 21,457. Approximately one third (6878; 32.1%) of the retrieved documents were published in the last three years of the study period. In total, 5451 (25.4%) documents were about refugees and asylum seekers, while 1328 (6.2%) were about migrant workers, 440 (2.1%) were about international students, 679 (3.2%) were about victims of human trafficking/smuggling, 26 (0.1%) were about patients' mobility across international borders, and the remaining documents were about unspecified categories of migrants. The majority of the retrieved documents (10,086; 47.0%) were in psychosocial and mental health domain, while 2945 (13.7%) documents were in infectious diseases, 6819 (31.8%) documents were in health policy and systems, 2759 (12.8%) documents were in maternal and reproductive health, and 1918 (8.9%) were in non-communicable diseases. The contribution of authors and institutions in Asian countries, Latin America, Africa, Middle East, and Eastern European countries was low. Literature in GMH represents the perspectives of high-income migrant destination countries. CONCLUSION: Our heat map of research output shows that despite the ever-growing prominence of human mobility across the globe, and Sustainable Development Goals of leaving no one behind, research output on migrants' health is not consistent with the global migration pattern. A stronger evidence base is needed to enable authorities to make evidence-informed decisions on migration health policy and practice. Research collaboration and networks should be encouraged to prioritize research in GMH

Irregular Migration as a Potential Source of Malaria Reintroduction in Sri Lanka and Use of Malaria Rapid Diagnostic Tests at Point-of-Entry Screening

Background. We describe an irregular migrant who returned to Sri Lanka after a failed people smuggling operation from West Africa. Results. On-arrival screening by Anti-Malaria Campaign (AMC) officers using a rapid diagnostic test (RDT) (CareStart Malaria HRP2/PLDH) indicated a negative result. On day 3 after arrival, he presented with fever and chills but was managed as dengue (which is hyperendemic in Sri Lanka). Only on day 7, diagnosis of Plasmodium falciparum malaria was made by microcopy and CareStart RDT. The initially negative RDT was ascribed to a low parasite density. Irregular migration may be an unrecognized source of malaria reintroduction. Despite some limitations in detection, RDTs form an important point-of-entry assessment. As a consequence of this case, the AMC is now focused on repeat testing and close monitoring of all irregular migrants from malaria-endemic zones. Conclusion. The present case study highlights the effective collaboration and coordination between inter-governmental agencies such as IOM and the Ministry of Health towards the goals of malaria elimination in Sri Lanka

Are left-behind families of migrant workers at increased risk of attempted suicide? – A cohort study of 178,000+ individuals in Sri Lanka

Background There are an estimated 258 million international migrants worldwide. In Asia low-skilled workers often emigrate on a temporary basis (2–3 years) without their families. There is significant concern over the mental health and wellbeing of left-behind families in this region. No previous study has examined whether the risk of suicidal behaviour is elevated in left-behind family members. Methods Cohort study using baseline data from a large randomised controlled trial in Sri Lanka (n = 178,730 participants; 8% households had a current temporary foreign migrant) and prospective hospital presentations of suicide attempts. Using multilevel Poisson regression models, we compared the risk of attempted suicide in households with left-behind and non-left-behind family members. We also investigated whether the sex of the migrant or the age/sex of the household member left behind altered any associations. Results The risk of an attempted suicide was elevated in female migrant households (IRR 1.60 95% CI 1.38, 1.85), but not male migrant households (IRR 1.01 95% CI 0.76,1.36)) with strong evidence that risk differed for female vs. male migrant households (p-value = 0.005). We found no evidence that the age or sex of the left-behind household member altered the association observed. Conclusions This analysis suggests that members of households with a temporary female foreign migrant are at an increased risk of attempted suicide, but these findings must be interpreted with caution. The increased risk of suicidal behaviour in these households may be due to factors that were present before the migration and persist post-migration (e.g. household violence, poverty)
