Cholera’s Shadow: How Conflict and Climate Change are Reshaping Africa’s Disease Landscape
Imagine a scenario: a mother in Darfur, Sudan, walks for miles in scorching heat, only to find the nearest water source contaminated, knowing each sip could endanger her children. This isn’t a dystopian future; it’s the reality for millions facing a surge in cholera outbreaks across Africa, a crisis exacerbated by conflict, climate change, and crumbling infrastructure. The continent could see over 200,000 cases and 6,000 deaths between September 2025 and February 2026, a chilling forecast demanding immediate and coordinated action.
The Perfect Storm: Conflict, Climate, and Cholera
Sudan’s current cholera outbreak, particularly devastating in Darfur, isn’t an isolated incident. It’s a stark symptom of a continent grappling with interconnected crises. Ongoing conflicts, like the one in Sudan, disrupt healthcare systems, displace populations, and create environments where basic sanitation collapses. Displacement dramatically increases the risk of transmission, as seen with cases already emerging in Chad’s refugee settlements bordering Sudan. Compounding this, extreme weather events – increasingly frequent due to climate change – overwhelm already fragile water and sanitation (WASH) infrastructure.
Ninety percent of Khartoum’s water treatment plants are currently non-functional, a terrifying statistic highlighting the vulnerability of urban centers. Flooding, like the recent event displacing nearly 900 people in North Darfur, further contaminates water sources and spreads disease. This isn’t just about cholera; Sudan is simultaneously battling outbreaks of dengue fever, diphtheria, measles, and pertussis, creating a complex and overwhelming public health challenge.
Beyond Sudan: A Pan-African Emergency
The situation in Sudan is a microcosm of a broader regional emergency. Cholera is surging across Africa, with 23 nations currently facing outbreaks. Countries like South Sudan, the Democratic Republic of Congo, and Angola are among the worst affected. This widespread resurgence exposes deep weaknesses in public health systems, highlighting the urgent need for investment and strengthening.
The Africa Centres for Disease Control and Prevention (Africa CDC) recognizes the scale of the problem. New figures show high cholera cases in all five Darfur states, with North Darfur accounting for 57% of cases and South Darfur bearing the heaviest death toll – 66 out of 136 deaths recorded so far in 2025. Crucially, under-reporting is a significant concern, meaning the true extent of the crisis is likely far greater than official numbers suggest.
The Continental Cholera Preparedness and Response Plan: A New Model for Action?
African leaders have responded with the Continental Cholera Preparedness and Response Plan 1.0, a six-month initiative requiring over $231 million in funding. Spearheaded by the Africa CDC and the World Health Organization (WHO), and championed by Zambian President H.E. Hakainde Hichilema, the plan aims to coordinate efforts, mobilize resources, and strengthen health systems.
What sets this plan apart is its emphasis on political leadership and cross-sectoral collaboration. It builds on the successful response model used during the mpox outbreak, leveraging the Incident Management Support Team (IMST) and its “4-One” principle – one team, one plan, one budget, one monitoring framework – to ensure strategic coherence and operational efficiency. This approach, as President Hichilema emphasizes, views cholera elimination not just as a health goal, but as a “moral imperative” and a catalyst for economic growth.
The Vaccine Gap and the Challenge of Access
While the Continental Cholera Preparedness and Response Plan offers a framework, a critical challenge remains: access to vaccines. In Darfur, oral cholera vaccine coverage is virtually non-existent, compared to a national average of just 5.4%. Ongoing civil conflict is the primary barrier, making large parts of the region inaccessible to vaccination teams. This leaves displaced populations, living in overcrowded camps, particularly vulnerable.
The uneven distribution of vaccines isn’t unique to Sudan. Across the continent, logistical challenges, funding constraints, and political instability hinder equitable access. Investing in local vaccine production capacity is crucial, reducing reliance on external sources and ensuring a more sustainable and responsive supply chain.

The Role of Technology and Data in Future Outbreak Prediction
Looking ahead, leveraging technology and data analytics will be essential for predicting and preventing future outbreaks. Real-time surveillance systems, coupled with machine learning algorithms, can identify hotspots and track the spread of disease with greater accuracy. This allows for targeted interventions, such as pre-emptive vaccination campaigns and rapid deployment of resources. Furthermore, mobile technology can be used to disseminate public health information and empower communities to take preventative measures.
Beyond Response: Addressing the Root Causes
Ultimately, controlling cholera requires addressing the underlying drivers of vulnerability. This means investing in sustainable WASH infrastructure, strengthening healthcare systems, and promoting peace and stability. It also requires tackling climate change and mitigating its impact on water resources and sanitation.
The interconnectedness of these challenges demands a holistic approach. For example, investing in climate-resilient agriculture can improve food security and reduce the risk of displacement, thereby lessening the strain on already overburdened resources. Similarly, promoting good governance and accountability can help ensure that resources are allocated effectively and reach those who need them most.
Frequently Asked Questions
What is the biggest obstacle to controlling cholera in Africa?
Conflict and political instability are arguably the biggest obstacles, as they disrupt healthcare systems, displace populations, and hinder access to essential resources like vaccines and clean water.
How effective are cholera vaccines?
Oral cholera vaccines are highly effective in preventing the disease, but they require multiple doses and consistent access to ensure long-term protection. Coverage rates remain a significant challenge.
What can individuals do to help prevent cholera outbreaks?
Practicing good hygiene, such as washing hands frequently with soap and water, drinking safe water, and properly disposing of waste, can significantly reduce the risk of infection. Supporting organizations working on the ground is also crucial.
Is climate change directly linked to the rise in cholera cases?
Yes, climate change exacerbates the conditions that favor cholera outbreaks. Extreme weather events like floods and droughts contaminate water sources and overwhelm sanitation systems, increasing the risk of transmission.
The cholera crisis in Sudan and across Africa is a stark reminder that health is inextricably linked to peace, stability, and environmental sustainability. Without addressing these fundamental issues, we risk perpetuating a cycle of outbreaks and suffering. The Continental Cholera Preparedness and Response Plan is a step in the right direction, but its success hinges on sustained funding, political will, and a commitment to addressing the root causes of this preventable disease.
