Sudan is facing a severe dengue fever outbreak compounded by ongoing conflict and deteriorating infrastructure, with tens of thousands affected across the country, especially in Khartoum. The surge in cases during the rainy season highlights the collateral damage of nearly 30 months of warfare that has crippled healthcare and essential services and fueled a concurrent rise in other infectious diseases like cholera and malaria.
Rising Dengue Fever Cases in Context
Over the week ending September 23, 2025, Sudan’s Ministry of Health reported more than 2,000 confirmed dengue cases nationwide, predominantly in the capital Khartoum. However, the actual number is believed to be much higher. Health Minister Haitham Mohamed Ibrahim estimated that 80% of cases are mild and do not seek hospital care, suggesting tens of thousands of infections across Sudan during the season.
The rainy season’s heavy rains have created ideal breeding grounds for the Aedes aegypti mosquitoes that transmit dengue virus. Standing pools of water in homes and streets—exacerbated by disrupted water and power supply systems—have led to a spike in mosquito populations. Disrupted municipal services mean trash accumulation and stagnant water remain unaddressed, as described by affected residents in Omdurman, a Khartoum suburb.
Public health infrastructure has suffered dramatic setbacks from sustained conflict between Sudan’s military and the paramilitary Rapid Support Forces (RSF). The fighting since 2023 has damaged water supply, power grids, and waste management systems that are vital for mosquito control programs such as insecticide spraying. These factors have created a “new reality” of heightened mosquito prevalence, according to the health minister.
Clinical Care & Disease Severity
Dengue fever presents a broad spectrum of illness ranging from mild febrile conditions to severe, potentially fatal complications on repeat infections, a phenomenon referred to as antibody-dependent enhancement. In overcrowded hospitals like Omdurman Hospital, many patients receive intravenous paracetamol and supportive care, the current standard treatment. Experts emphasize that while 80% of cases are mild, severe forms require prompt hospitalization to prevent complications such as dengue hemorrhagic fever or dengue shock syndrome.reuters+1
Expert Commentary
Dr. Samira Abdelrahman, Infectious Disease Specialist not involved in the Sudan outbreak response, explains, “In conflict settings where healthcare is disrupted, containment of dengue becomes extremely challenging. Prevention strategies—particularly vector control and public education—are critically undermined. The current surge is consistent with what we expect when infrastructure and public services collapse.”
Implications for Public Health
The outbreak illustrates how war and political conflict can trigger secondary health emergencies through ecosystem disruption and weakened health systems. It underscores the urgent need for coordinated humanitarian aid, including funding, vaccination campaigns for concurrent infections like cholera, and restoration of water and waste services to reduce mosquito breeding sites.
The Sudanese government has called for $39 million in emergency funding to tackle simultaneous epidemics, signaling that international support remains critical as the health system is less than one-third funded by donor aid.
Limitations & Challenges
Addressing the dengue epidemic is complicated by the ongoing conflict that impedes humanitarian access and resource allocation. The true scale of the outbreak may be underestimated due to limited testing and underreporting from conflict zones. Additionally, the response capacity is overwhelmed by the convergence of malaria, cholera, and malnutrition crises affecting displaced and vulnerable populations. These intersecting health emergencies highlight the complexity of managing outbreaks in war-torn settings.
Practical Implications for Readers
For residents and health-conscious individuals, preventing mosquito bites by using mosquito nets, eliminating standing water around homes, and protecting water supplies are crucial preventive steps. Awareness of dengue symptoms—fever, severe headache, joint and muscle pain, rash—is important for early medical consultation. Health authorities recommend seeking immediate care if symptoms worsen or if there is a history of previous dengue infection. Repeated infections increase the risk of severe disease.
Summary
Sudan’s dengue fever outbreak, driven by the ongoing war’s devastation of infrastructure and health services, signals a dire public health emergency amid complex humanitarian challenges. The epidemic highlights the interplay between conflict, environmental changes, and infectious diseases, calling for urgent international aid and robust public health interventions.
