After three years of conflict, Sudan faces a deepening humanitarian health crisis with 34 million people requiring aid, 21 million lacking essential health services, and disease outbreaks surging amid repeated attacks on medical infrastructure. The World Health Organization reports that 37% of health facilities remain non-functional, over 4 million are acutely malnourished, and malaria, dengue, measles, polio, hepatitis E, meningitis, and diphtheria are spreading across 13 of Sudan’s 18 states. WHO has verified 217 attacks on health care since April 2023, resulting in 2,052 deaths and 810 injuries, further crippling access in conflict-affected regions like Darfur and Kordofan. Despite challenges, WHO has delivered over 3,300 metric tons of medical supplies since 2023, supported vaccination campaigns reaching 46 million people, and treated over 118,000 children for severe acute malnutrition. The introduction of malaria vaccines into Sudan’s routine immunization program marks a historic public health milestone in the region. Sustained humanitarian access, protection of health workers, and long-term funding are critical to prevent further deterioration and lay the groundwork for recovery once peace is achieved.
The Collapse of Sudan’s Health System: A Three-Year Toll
Sudan’s health infrastructure has deteriorated catastrophically since the outbreak of armed conflict in April 2023. Repeated bombardments, looting, and occupation of hospitals have left 37% of the country’s health facilities non-functional, according to WHO surveillance data. In East Darfur, the destruction of El Daein Teaching Hospital—a critical referral center serving hundreds of thousands—has severed access to emergency obstetric care, blood transfusions, and pediatric intensive care for a vast rural population. Ambulances have been hijacked or destroyed, and health workers face daily threats, with over 800 injured and more than 2,000 killed in verified attacks on health care since the conflict began. These violations contravene international humanitarian law, including the Geneva Conventions, which protect medical personnel and facilities during armed conflict. The erosion of trust in health services has led many to avoid seeking care even when available, exacerbating preventable deaths from treatable conditions.
Disease Outbreaks Thrive in the Vacuum of Collapsed Surveillance
With disease surveillance systems disrupted and routine immunization programs halted in active conflict zones, Sudan has become a breeding ground for infectious outbreaks. Malaria transmission has intensified due to disrupted vector control and increased exposure from displacement, with Plasmodium falciparum—the most deadly strain—accounting for over 80% of cases in endemic states like Gedaref and White Nile. Dengue fever, transmitted by Aedes aegypti mosquitoes breeding in stagnant water around crowded displacement camps, has surged in Khartoum and River Nile states. Measles, a highly contagious virus spread via respiratory droplets, has infected over 15,000 children in 2025 alone, fueled by plummeting vaccination coverage below the 95% threshold needed for herd immunity. Circulating vaccine-derived poliovirus type 2 (cVDPV2) has been detected in sewage samples from Darfur, indicating ongoing community transmission despite national immunization days. Hepatitis E, spread through fecal contamination of drinking water, poses a severe risk to pregnant women, with case fatality rates reaching 25% in this group during outbreaks. Meningitis epidemics, driven by Neisseria meningitidis serogroup W and facilitated by overcrowding and limited access to antibiotics like ceftriaxone, have clustered in Kordofan and Darfur. Diphtheria, caused by toxin-producing Corynebacterium diphtheriae, has re-emerged in areas with low diphtheria-tetanus-pertussis (DTP3) vaccine coverage, threatening unvaccinated children with pseudomembrane formation and myocarditis.
In Plain English: The Clinical Takeaway
- Malnutrition weakens the body’s ability to fight infections, making common diseases like malaria and measles far more deadly—especially for children under five and pregnant women.
- Vaccines remain one of the most effective tools we have. restoring routine immunization, even in hard-to-reach areas, can prevent outbreaks before they start.
- Protecting hospitals and health workers isn’t just ethical—it’s a direct lifeline for millions who rely on these facilities for emergency care, maternal health, and chronic disease management.
Geo-Epidemiological Bridging: Lessons from Global Health Systems
The collapse of Sudan’s health system contrasts sharply with the resilience seen in high-income nations during crises. In the United Kingdom, the National Health Service (NHS) maintains surge capacity through centralized supply chains, regional oxygen networks, and legal protections for health workers during emergencies. Similarly, the European Medicines Agency (EMA) expedites regulatory pathways for essential medicines during public health crises, ensuring rapid deployment of vaccines and antivirals. In Sudan, the absence of such systems means that even when vaccines arrive—such as the novel malaria vaccine RTS,S/AS01 (Mosquirix), which targets the Plasmodium falciparum circumsporozoite protein to block liver invasion—delivery is hampered by insecurity and broken cold chains. The WHO’s success in introducing this vaccine into Sudan’s routine program in early 2026, making it the first country in the WHO Eastern Mediterranean Region to do so, represents a significant achievement. But, sustaining coverage requires functional health centers, trained vaccinators, and community trust—all eroded by conflict. Unlike the U.S. Food and Drug Administration (FDA), which can issue Emergency Use Authorizations (EUAs) to fast-track countermeasures, Sudan lacks a national regulatory agency with equivalent authority, relying entirely on WHO prequalification and UNICEF procurement channels. This dependency creates vulnerabilities when global supply chains falter or funding fluctuates.
Funding Gaps and the Politics of Humanitarian Aid
The WHO’s Sudan Health Response Plan 2026 calls for $428 million to sustain essential health services, yet as of April 2026, only 38% has been funded. Major contributors include the European Commission’s Humanitarian Aid and Civil Protection department (ECHO), the United States Agency for International Development (USAID), and the Kingdom of Saudi Arabia through the King Salman Humanitarian Aid and Relief Centre (KSrelief). Private philanthropies such as the Bill & Melinda Gates Foundation have supported specific interventions, including malaria vaccine rollout and malnutrition treatment programs. However, funding remains highly fragmented and short-term, with most grants awarded in 3- to 6-month cycles, undermining efforts to rebuild resilient health systems. A 2025 analysis published in The Lancet Global Health found that humanitarian health aid to conflict zones is often reactive rather than preventive, with less than 15% allocated to long-term system strengthening. Transparency in funding allocation is critical; audits by the Office of the United Nations High Commissioner for Refugees (UNHCR) have previously identified delays in fund disbursement and duplication of efforts among NGOs operating in the same geographic areas.
“In protracted conflicts like Sudan’s, we must shift from emergency patchwork to building back better—even amid insecurity. That means investing in cold chain infrastructure, training community health workers, and negotiating humanitarian pauses for vaccination campaigns. Health is not a luxury to be restored after peace; it is the foundation upon which peace is built.”
“The re-emergence of vaccine-preventable diseases in Sudan is a direct consequence of broken health systems, not vaccine hesitancy. When mothers walk 50 kilometers to reach a functioning clinic, only to identify it closed due to an attack, we fail them—not the other way around.”

Contraindications & When to Consult a Doctor
This section does not describe a medical treatment but outlines critical guidance for individuals in Sudan navigating the health crisis. There are no pharmacological contraindications to seeking care; rather, barriers are systemic and environmental. Individuals should avoid traveling to health facilities during active bombardment or when armed groups are known to operate near clinics—prioritizing personal safety is essential. However, certain symptoms warrant immediate risk-taking to reach care: difficulty breathing or chest pain (possible pneumonia, heart failure, or pulmonary embolism); sudden weakness or numbness on one side of the body (stroke); seizures or loss of consciousness (meningitis, cerebral malaria, or eclampsia in pregnancy); persistent vomiting or inability to retain fluids (severe dehydration from cholera or malaria); and fever lasting more than 48 hours in a child under five (possible malaria, pneumonia, or sepsis). Pregnant women experiencing vaginal bleeding, severe abdominal pain, or decreased fetal movement should seek emergency obstetric care immediately, as delays increase the risk of hemorrhage, obstructed labor, or uterine rupture. Malnourished children with edema, extreme lethargy, or skin lesions need urgent assessment for severe acute malnutrition with medical complications, which requires therapeutic feeding and antibiotics under supervision. In all cases, if a functioning health facility is inaccessible due to insecurity, individuals should contact community health workers or hotlines operated by WHO partners where available for remote triage and guidance.
The path forward for Sudan’s health system depends on three non-negotiables: an immediate cessation of attacks on health care, sustained and flexible funding for both emergency response and system rebuilding, and unimpeded humanitarian access to all regions. Without peace, no amount of medical intervention can fully reverse the damage—but with coordinated global support, even in the midst of conflict, lives can be saved, outbreaks contained, and the foundations of recovery laid. The introduction of the malaria vaccine into Sudan’s routine program is not just a medical milestone; it is a testament to what is possible when science, logistics, and determination converge amid adversity. Now, the world must match that resolve with unwavering commitment to the people of Sudan.
