|
ScienceDirect
Publication Type
Article

Protecting the health of migrants and refugees during the pandemic was a significant challenge in the Latin American region. We aimed to describe and contrast the response of the health systems of Mexico, Colombia and Perú to migrants' and refugees’ health needs during the COVID-19 pandemic, and to situate the response in the context of the migration and health policies of each country.

Sexual and reproductive health implementation research in humanitarian contexts: a scoping review

|
BMC Reproductive Health
Publication Type
Article

Meeting the health needs of crisis-affected populations is a growing challenge, with 339 million people globally in need of humanitarian assistance in 2023. Given one in four people living in humanitarian contexts are women and girls of reproductive age, sexual and reproductive health care is considered as essential health service and minimum standard for humanitarian response. Despite growing calls for increased investment in implementation research in humanitarian settings, guidance on appropriate methods and analytical frameworks is limited.

Case-area targeted interventions during a large-scale cholera epidemic: A prospective cohort study in Northeast Nigeria

|
National Library of Medicine
Publication Type
Article

Cholera outbreaks are on the rise globally, with conflict-affected settings particularly at risk. Case-area targeted interventions (CATIs), a strategy whereby teams provide a package of interventions to case and neighboring households within a predefined "ring," are increasingly employed in cholera responses. However, evidence on their ability to attenuate incidence is limited.

COVID-19 epidemiology, health services utilisation and health care seeking behaviour during the first year of the COVID-19 pandemic in Mweso health zone, Democratic Republic of Congo

|
Journal of Global Health
Publication Type
Article

Although the evidence about coronavirus disease 2019 (COVID-19) has increased exponentially since the beginning of the pandemic, less is known about the direct and indirect effects of the pandemic in humanitarian settings. In the Democratic Republic of the Congo (DRC), most studies occurred in Kinshasa and other cities. Limited research was conducted in remote conflict-affected settings. We investigated the COVID-19 epidemiology, health service utilisation, and health care-seeking behaviour during the first year of the pandemic (March 2020–March 2021) in the Mweso health zone, North Kivu, DRC.

How integration of refugees into national health systems became a global priority: a qualitative policy analysis

|
BMC Conflict and Health
Publication Type
Article

Despite a long history of political discourse around refugee integration, it wasn’t until 2016 that this issue emerged as a global political priority. Limited research has examined the evolution of policies of global actors around health service provision to refugees and how refugee integration into health systems came onto the global agenda. This study seeks to fill this gap.

The CHH–Lancet Commission on Health, Conflict, and Forced Displacement: reimagining the humanitarian system

|
The Lancet
Publication Type
Commentary

International humanitarian law is routinely being broken with impunity in conflicts globally. Populism tinged with anti-refugee discourse has led to a weakening of asylum and refugee law in many countries.  While special protection of hospitals and ambulances was previously largely respected by warring parties under the Geneva Conventions, attacks on health care have become the norm. With conflict-related deaths at a 26-year record high and more than 110 million people forcibly displaced worldwide at the end of June, 2023, the humanitarian system is overwhelmed, despite increases in humanitarian support from public and private donors.  As one of us (PBS) wrote in The Lancet in 2017: “An unprecedented number of humanitarian emergencies of large magnitude and duration is causing the largest number of people in a generation to be forcibly displaced. Yet the existing humanitarian system was created for a different time and is no longer fit for purpose.”

The impact of policy and policy communication on COVID-19 vaccination inequalities among Venezuelan refugees and migrants in Colombia: a comparative cross-sectional interrupted time-series analysis

|
BMJ Global Health
Publication Type
Article

Abstract

Introduction

Equitable access to vaccines for migrants and refugees is necessary to ensure their right to health and to achieve public health goals of reducing vaccine-preventable illness. Public health policies require regulatory frameworks and communication to effect uptake of effective vaccines among the target population. In Colombia, the National COVID-19 Vaccination Plan implicitly included Venezuelan refugees and migrants; however, initial communication of the policy indicated that vaccine availability was restricted to people with regular migration status. We estimated the impact of a public announcement, which clarified access for refugees and migrants, on vaccination coverage among Venezuelans living in Colombia.

Methods 

Between 30 July 2021 and 5 February 2022, 6221 adult Venezuelans participated in a cross-sectional, population-based health survey. We used a comparative cross-sectional time-series analysis to estimate the effect of the October 2021 announcement on the average biweekly change in COVID-19 vaccine coverage of Venezuelans with regular and irregular migration status.

Results 

71% of Venezuelans had an irregular status. The baseline (preannouncement) vaccine coverage was lower among people with an irregular status but increased at similar rates as those with a regular status. After the announcement, there was a level change of 14.49% (95% CI: 1.57 to 27.42, p=0.03) in vaccination rates among individuals with irregular migration status with a 4.61% increase in vaccination rate per biweekly period (95% CI: 1.71 to 7.51, p=0.004). By February 2022, there was a 26.2% relative increase in vaccinations among individuals with irregular migration status compared with what was expected without the announcement.

Conclusion

 While there was no policy change, communication clarifying the policy drastically reduced vaccination inequalities across migration status. Lessons can be translated from the COVID-19 pandemic into more effective global, regional and local public health emergency preparedness and response to displacement.

Chemical and Biological Threats: Guidance for Breastfeeding Women, Infants, and Young Children

|
Health Security
Publication Type
Article

In today's modern warfare, there is a growing risk of chemical and biological weapons use. Despite the widespread adoption of the United Nations Biological and Toxin Weapons Convention1 in 1975 and the Chemical Weapons Convention2 in 1997, we have seen notable examples of state-sponsored use of agents on vulnerable populations, as well as the use by individuals and nonstate actors.3-7 With the rise in acts of terrorism and conflict, there is an increased likelihood of exposure to chemical or biological agents by women and young children, who often represent the most vulnerable among the population. Children aged 0 to 5 years carry the most significant burden of conflict-related deaths of all age groups.8 Women of reproductive age who live in conflict zones have 3 times higher mortality than women who live in predominantly conflict-free settings.9

Despite the stark evidence of severe short- and long-term impacts of conflict on women and young children, this population has historically been overlooked when it comes to setting policy or providing holistic or human-centered guidance in conflict settings.10 There are abundant guidelines and research available on chemical and biological threats and how the general population could be impacted, as well as references to the treatment of breastfeeding women when discussing antidotes, vaccines, and drug treatments. However, there is very little guidance on whether women can safely continue to breastfeed after specific chemical and biological events and at what point breastfeeding can be safely resumed. Current information about breastfeeding safety in this scenario is disparate and hard to find.

UNRWA at the frontlines: managing health care in Gaza during catastrophe

|
The Lancet
Publication Type
Commentary

Abstract

The humanitarian situation in the Gaza Strip is untenable. An estimated 1·7 million people—over 75% of the population—have been displaced across Gaza as of Jan 30, 2024, often multiple times. Families have been forced to move multiple times in search of safety. According to local authorities, as of Jan 7, 2024, at least 26 901 Palestinians have been killed, 65 949 have been injured, and 7780 are missing, mostly under the rubble. Access to life-saving health services has been severely affected. Electricity, fuel, water, and medicines are either in very short supply or non-existent.  

 

Throughout this war—and before it, amid years of blockade—the UN Relief and Works Agency (UNRWA) has been a lifeline for people in Gaza. As of Jan 31, 2024, nearly 1·7 million displaced people are now sheltering in emergency shelters (both UNRWA and public shelters), informal sites, or in close vicinity to UNRWA shelters and distribution sites within host communities.

Simplified treatment protocols improve recovery of children with severe acute malnutrition in South Sudan: results from a mixed methods study

|
Journal of Health, Population and Nutrition
Publication Type
Article

As part of COVID-19 mitigation strategies, emergency nutrition program adaptations were implemented, but evidence of the effects is limited. Compared to the standard protocol, the full adapted protocol included adapted admissions criteria, simplified dosing, and reduced visit frequency; partially adapted protocols consisting of only some of these modifications were also implemented. To enable evidence-based nutrition program modifications as the context evolved, this study was conducted to characterize how protocol adaptations in South Sudan affected Outpatient Therapeutic Feeding Program outcomes.

Health care utilisation in Cox’s Bazar district, Bangladesh, during the first year of the COVID-19 pandemic: A mixed-methods study among host communities

|
Global Public Health
Publication Type
Article

To respond to the COVID-19 pandemic, countries introduced public health and social measures that had indirect societal, economic consequences. Concerns during epidemics include continuity of routine health services. We investigate how healthcare utilisation and healthcare seeking behaviour changed during the first year of the COVID-19 pandemic among host communities in Cox’s Bazar, Bangladesh. This mixed-methods study combines quantitative analyses of routine health data and population-based findings about healthcare seeking behaviours. Trends in consultations changed according to facility level (higher-level facilities included Upazila Health Complexes and District Hospitals; lower-level facilities included Community Clinics and Union Health and Family Welfare Centers). At the pandemic’s beginning, drops were seen at higher-level health facilities for outpatient department (OPD) consultations, respiratory infections, and antenatal care. Minor reductions or increases were seen at lower-level facilities for the same services. Half of the subdistricts reported a cumulative increase in OPD and respiratory tract infection consultations. Most subdistricts reported a cumulative decrease in antenatal care. Child vaccinations dropped in all subdistricts, half of which did not catch-up, resulting in a cumulative decrease of delivered doses. Fear of contracting COVID-19 and financial constraints were the main reasons for decreased access. Drivers of healthcare seeking behaviours should be better understood to guide preparedness and service delivery modalities at primary and secondary levels.

Pregnant women in Gaza require urgent protection

|
The Lancet
Publication Type
Commentary

The ongoing war in Gaza has led to unprecedented death and destruction.  Hostilities continue to have a dire effect on the 2·2 million people living in Gaza, with particular and acute effects on the estimated 52 000 women who are currently pregnant.  At the time of writing, around 1·93 million people in Gaza (85% of the population) have been displaced and over 18 205 lives have been lost; of these lives lost, 5153 were women and 7729 were children, constituting 70% of the fatalities. Indirect causes of excess mortality, including from unmanaged obstetric complications, are expected to increasingly contribute to death.

Critical research gaps in treating growth faltering in infants under 6 months: A systematic review and meta-analysis

|
PLOS Global Public Health
Publication Type
Article

In 2020, 149.2 million children worldwide under 5 years suffered from stunting, and 45.4 million experienced wasting. Many infants are born already stunted, while others are at high risk for growth faltering early after birth. Growth faltering is linked to transgenerational impacts of poverty and marginalization. Few interventions address growth faltering in infants under 6 months, despite a likely increasing prevalence due to the negative global economic impacts of the COVID-19 pandemic. Breastfeeding is a critical intervention to alleviate malnutrition and improve child health outcomes, but rarely receives adequate attention in growth faltering interventions. A systematic review and meta-analysis were undertaken to identify and evaluate interventions addressing growth faltering among infants under 6 months that employed supplemental milks. The review was carried out following guidelines from the USA National Academy of Medicine. A total of 10,405 references were identified, and after deduplication 7390 studies were screened for eligibility. Of these, 227 were assessed for full text eligibility and relevance. Two randomized controlled trials were ultimately included, which differed in inclusion criteria and methodology and had few shared outcomes. Both studies had small sample sizes, high attrition and high risk of bias. A Bangladeshi study (n = 153) found significantly higher rates of weight gain for F-100 and diluted F-100 (DF-100) compared with infant formula (IF), while a DRC trial (n = 146) did not find statistically significant differences in rate of weight gain for DF-100 compared with IF offered in the context of broader lactation and relactation support. The meta-analysis of rate of weight gain showed no statistical difference and some evidence of moderate heterogeneity. Few interventions address growth faltering among infants under 6 months. These studies have limited generalizability and have not comprehensively supported lactation. Greater investment is necessary to accelerate research that addresses growth faltering following a new research framework that calls for comprehensive lactation support.

No evidence of inflated mortality reporting from the Gaza Ministry of Health

|
The Lancet
Publication Type
Letter

Mortality reporting is a crucial indicator of the severity of a conflict setting, but it can also be inflated or under-reported for political purposes. Amidst the ongoing conflict in Gaza, some political parties have indicated scepticism about the reporting of fatalities by the Gaza Ministry of Health (MoH). The Gaza MoH has historically reported accurate mortality data, with discrepancies between MoH reporting and independent United Nations analyses ranging from 1·5% to 3·8% in previous conflicts. A comparison between the Gaza MoH and Israeli Foreign Ministry mortality figures for the 2014 war yielded an 8·0% discrepancy.  Public scepticism of the current reports by the Gaza MoH might undermine the efforts to reduce civilian harm and provide life-saving assistance.

A premature newborn born to an adolescent girl with acute Ebola virus disease and malaria survives in a resource‐limited setting in an Ebola treatment unit in DR Congo: “A case report”

|
Clinical Case Reports
Publication Type
Report

This case describes rare preterm newborn survival in the setting of an Ebola treatment unit in Eastern DRC. The neonate was born vaginally to an acutely ill 17‐year‐old mother who was vaccinated against Ebola virus after being identified as a contact of her father, who was a confirmed case and who did not survive his infection. This woman was admitted to an Ebola treatment unit at 32 weeks of gestation and given monoclonal antibody treatment. She gave birth vaginally, succumbing to postpartum hemorrhage 14 h after delivery. This child survived despite compounding vulnerabilities of preterm birth and maternal Ebola infection. Despite a negative test for EVD, the neonate was given a single dose of monoclonal antibody therapy in the first days of life. We believe maternal vaccination and neonatal monoclonal antibody treatment contributed to the child's survival. The circumstances surrounding neonatal survival in this extremely resource‐limited context must be analyzed and disseminated in order to increase rates of neonatal and maternal survival in future outbreaks. Maternal and neonatal health are critical aspects of outbreak response that have been understudied and underreported leaving clinicians severely underresourced to provide life‐saving care in outbreak settings. Pregnancy and childbirth do not stop in times of disease outbreak, adequate equipment and trained staff required for quality neonatal care must be considered in future outbreak responses.
