Health Doesn’t End at the Border: The Long‑Term Medical Needs of Displaced Communities
When people flee war or disaster, the world often focuses on the moment of escape, the border crossing, the emergency tents, the first medical check. But for millions of displaced people, the real health crisis begins after they reach safety. Chronic illnesses go untreated, mental health deteriorates under prolonged uncertainty and climate stress deepens existing vulnerabilities.
Refugees and migrants consistently face poorer health outcomes than host populations, shaped not only by the violence they escape but also by the conditions they endure during displacement and the policies of the countries that receive them. Climate change, conflict and shrinking humanitarian budgets are converging to create a long-term emergency that rarely makes headlines.
Beyond the Journey: How Displacement Reshapes Health Worldwide
More people are on the move today than at any point in modern history. Their health is shaped by every phase of their journey: the trauma of leaving home, the dangers of travel and the instability of life in a new country. Contrary to common misconceptions, displaced people do not increase the risk of communicable diseases in host communities. Instead, their health risks arise from the conditions they face along the way:
- limited access to clean water and sanitation
- inadequate shelter and food
- disrupted access to essential health services
- exposure to violence, including gender‑based violence
- prolonged uncertainty and psychological stress
These factors create a perfect storm of vulnerability. Refugees may arrive with injuries, infections or untreated chronic conditions, but the deeper health impacts often emerge months or years later.
Climate change adds another layer, reshaping migration routes and amplifying risks through heatwaves, floods and droughts, yet displaced communities are often excluded from national climate adaptation plans.
The Most Common Health Issues Among Displaced Populations
Across contexts, certain health patterns repeat themselves. Chronic diseases are among the most overlooked. Conditions like diabetes, hypertension, asthma, or cancer require continuity of care, something humanitarian systems, designed for short-term emergencies, struggle to provide. As a result, illnesses worsen silently.
Mental health is another major concern. Many refugees experience anxiety, depression, sleep disturbances or PTSD linked to conflict, loss, and prolonged uncertainty. These issues are often intensified by poor living conditions, lack of work and the feeling of being “stuck” with no future.
Malnutrition remains a structural problem. Food rations have been cut in many regions and families often survive on one meal a day. This affects everything from children’s growth to adults’ immunity, increasing vulnerability to infections and chronic fatigue.
Women and girls face additional risks, including sexual violence during displacement and limited access to reproductive health services. Pregnant women often miss antenatal care, give birth in unsafe conditions, or struggle to register their newborns, a bureaucratic barrier that can determine whether a child receives food or healthcare.
When Healthcare Exists but Remains Out of Reach
Even when services exist, reaching them is another challenge. Many refugees live far from clinics, face discrimination, or lack the legal documents needed to access care. Language barriers, high out‑of‑pocket costs and the absence of culturally sensitive services further complicate access.
In humanitarian settings, insecurity and damaged infrastructure disrupt supply chains and limit the presence of medical staff. Clinics may close during conflict, medicines may run out and health workers may be unable to reach the camp. These barriers affect both refugees and host communities, creating a shared crisis of access.
Women, children, people with disabilities and those in irregular legal situations face the highest risks. Without inclusive and accessible systems, the right to health remains out of reach for many displaced people.
Inside Nguenyyiel: A Health System Stretched Beyond Survival
This case study draws on a series of in‑depth interviews conducted by Martina Boaretto, a PhD researcher who spent several weeks inside Nguenyyiel Refugee Camp on the Ethiopia–South Sudan border. Working closely with health workers, refugee leaders and families, she documented the everyday realities of long‑term displacement, realities that rarely make it into official reports. Her conversations reveal a camp where chronic illnesses go untreated, food insecurity shapes daily life and insecurity can shut down the entire health system overnight. Through these testimonies, we gain a ground‑level view of what it means to live in a place designed for emergencies but inhabited for more than a decade.
One of the clearest gaps is chronic care. Martina met a father who had sold five cows and flown his son to Juba for treatment of a chronic throat disease, a journey costing around $300 each way. When the illness returned, he simply couldn’t afford to go again. “Medications for chronic diseases are not available in the camp,” he said, echoing what health workers repeatedly confirmed. Malnutrition is equally entrenched. Clinicians working in the camp described it as “structural”: families rely entirely on food rations that have been cut by 40% in recent years, leaving many to eat only once a day. The consequences are visible everywhere: gastrointestinal problems, weakened immunity and anemia affecting more than 80% of the population.
Mental health is under constant strain. Health workers spoke of deep depression, especially among men who feel unable to provide for their families. Alcohol abuse is common. Women carry hidden trauma, including sexual violence during displacement, a reality rarely spoken aloud but widely understood. Mobility adds another layer of risk. Refugees move between zones, between camps and back to South Sudan. Women often travel home to conceive and return to Ethiopia for safer delivery, a cycle that leads to missed antenatal care and dangerous births on the road. Many, health workers say, come back “in worse condition” after months away.
And then there are the barriers that cost lives. Families in peripheral zones walk up to six kilometers to reach care. Health Posts do not operate at night, leaving the camp dependent on a single Health Center for after‑hours care, one facility for more than 100,000 people. Refugee leaders recalled a woman who died simply because help wasn’t available after dark. Security makes everything harder. Recent clashes blocked the main road for weeks, leaving women to deliver at home, malaria untreated and children without vaccinations. “People died in this period,” a clinician said. Even water became a threat: destroyed pumps forced refugees to walk long distances to other camps, a journey described as “fatal” due to insecurity.
Nguenyyiel is a stark reminder that displacement doesn’t pause at the border. It reshapes every aspect of health, day after day, year after year. And demands a response that goes far beyond emergency care.
Health Beyond the Border
Displacement doesn’t end when someone reaches safety. Neither do their health needs. Chronic diseases require continuity of care. Mental health requires long-term support. Climate stress requires adaptation. And humanitarian systems must evolve from emergency response to sustainable health provision.
If we want displaced communities not just to survive, but to live with dignity, we must build health systems that recognize one simple truth: health doesn’t end at the border.
