Africa is facing an alarming surge in disease outbreaks, with the Africa Centres for Disease Control and Prevention (Africa CDC) sounding the alarm over the continent’s escalating public health challenges. The rise in cases of infectious diseases, particularly cholera, has become a pressing concern, exposing vulnerabilities in health systems and threatening lives across multiple countries. In recent years, the situation has taken a grave turn, with interconnected crises driving the outbreaks to unprecedented levels.

Cholera: A Persistent and Growing Threat
Among the various outbreaks, cholera has emerged as the leading cause of death. The disease, caused by the ingestion of water or food contaminated with Vibrio cholerae bacteria, has plagued several African nations, leading to thousands of fatalities in recent years. In 2024 alone, countries such as Malawi, Mozambique, and Nigeria reported record-breaking cholera cases, driven by factors such as flooding, displacement, and inadequate access to clean water and sanitation.
The World Health Organization (WHO) estimates that cholera affects 1.3 to 4 million people globally each year, but its burden in Africa remains disproportionately high. In the aftermath of severe weather events linked to climate change, cholera outbreaks have become more frequent and intense. For instance, Cyclone Freddy in 2024 exacerbated waterborne diseases in south-eastern Africa, leading to a sharp increase in cholera cases. In addition to natural disasters, poor waste management and lack of investment in water infrastructure have fuelled the disease’s spread, making it a year-round threat in many regions.
The Human Toll and Economic Impact
The human cost of cholera outbreaks extends beyond mortality rates. Survivors often endure long-term health complications, and communities face disruptions to livelihoods, education, and economic stability. In rural areas, cholera can decimate agricultural productivity as infected water sources spread the disease to livestock and crops. Urban centres, meanwhile, grapple with overwhelmed healthcare facilities and significant economic losses as businesses shut down during outbreaks.
For families already living in poverty, the financial burden of treating cholera is often insurmountable. The cost of hospital stays, medication, and transportation to healthcare centres leaves many in debt, perpetuating cycles of poverty. Governments also face mounting costs, as emergency responses divert funds from long-term development projects, hindering progress in other critical sectors.
Underlying Causes of Disease Outbreaks
While cholera takes centre stage, other diseases such as malaria, measles, and Ebola are also on the rise. Africa CDC attributes the growing threat of infectious diseases to a confluence of factors, including:
- Climate Change: Extreme weather events such as floods and droughts disrupt ecosystems and create favourable conditions for disease transmission. Rising temperatures have also expanded the habitats of vectors like mosquitoes, increasing the prevalence of malaria and dengue fever.
- Rapid Urbanization: The expansion of urban slums without adequate sanitation or healthcare infrastructure increases exposure to infectious agents. In cities like Lagos and Kinshasa, population density has reached critical levels, overwhelming local governments’ ability to provide clean water and waste management services.
- Weak Health Systems: Many African nations lack the resources to implement robust disease surveillance and rapid response mechanisms. Underfunded healthcare facilities often operate without essential supplies, leaving them ill-equipped to handle outbreaks.
- Conflict and Displacement: Political instability and violence have displaced millions, forcing them into overcrowded refugee camps with limited access to basic needs. These conditions are breeding grounds for infectious diseases, as clean water and sanitation are frequently unavailable.
- Global Supply Chain Disruptions: The COVID-19 pandemic highlighted vulnerabilities in global supply chains, which have continued to affect the availability of vaccines, medical supplies, and laboratory reagents needed for outbreak control.
Africa CDC’s Call to Action
To address the growing crisis, Africa CDC has outlined a multipronged strategy:
- Strengthening Surveillance: Africa CDC is working with member states to enhance early detection and monitoring of outbreaks through improved laboratory networks and real-time data sharing. Regional collaboration is being prioritized to prevent cross-border transmission.
- Expanding Vaccination Campaigns: Targeted vaccination efforts against cholera, measles, and other preventable diseases are being scaled up, especially in high-risk areas. Africa CDC has also partnered with international organizations to secure vaccine stockpiles for emergency use.
- Improving Water and Sanitation: Investments in clean water, proper sanitation, and hygiene education are crucial for reducing waterborne diseases like cholera. Governments are being urged to prioritize infrastructure projects that ensure access to safe drinking water in both urban and rural areas.
- Capacity Building: Training healthcare workers and equipping health facilities with necessary resources are key to improving response efforts. Africa CDC has launched several programs to enhance the technical expertise of frontline workers and strengthen supply chain management.
- Climate Resilience: Developing strategies to mitigate the health impacts of climate change is becoming a priority for the Africa CDC. This includes implementing early warning systems for extreme weather events and integrating climate adaptation measures into public health planning.
The Role of Technology in Outbreak Response
Emerging technologies are playing a critical role in combating disease outbreaks. Mobile health applications and artificial intelligence are being used to track disease spread, predict outbreak hotspots, and coordinate responses. In Uganda, for instance, a mobile-based disease surveillance system has significantly improved the speed and accuracy of reporting cholera cases. Additionally, drones are being deployed to deliver medical supplies to remote areas, ensuring timely access to life-saving interventions.
Telemedicine has also emerged as a powerful tool in bridging the gap between patients and healthcare providers. During the COVID-19 pandemic, many African nations adopted telehealth platforms to maintain continuity of care. These platforms are now being adapted to support outbreak management, providing communities with vital health information and reducing the need for in-person consultations during epidemics.
International Support and Collaboration
Africa’s battle against disease outbreaks requires global solidarity. Organizations such as WHO, UNICEF, and the World Bank have pledged support, but more is needed to address funding gaps and ensure equitable distribution of resources. Regional partnerships and community-based interventions are also crucial to achieving long-term health security.
The African Union has called for increased investment in the continent’s health sector, urging member states to allocate at least 15% of their national budgets to healthcare in line with the Abuja Declaration. However, many countries remain far from meeting this target, highlighting the need for innovative financing mechanisms such as public-private partnerships and global health funds.
Community Engagement: A Pillar of Outbreak Control
Community involvement is essential for effective disease control. Public awareness campaigns that educate communities about disease prevention, symptoms, and treatment options can significantly reduce transmission rates. Traditional and religious leaders have been enlisted in several countries to promote health interventions, such as vaccination drives and hygiene practices.
In addition, empowering communities to take ownership of local health initiatives has proven successful in reducing disease burden. In Kenya, community health volunteers have been trained to conduct household visits, distribute chlorine tablets, and provide education on safe water practices. These grassroots efforts have led to measurable declines in cholera cases in affected regions.
A Path Forward
The rise in disease outbreaks underscores the urgent need for systemic reforms in Africa’s public health infrastructure. While challenges abound, Africa CDC’s proactive measures and growing international support provide a glimmer of hope. Addressing the root causes of outbreaks, enhancing resilience to climate impacts, and ensuring access to basic healthcare services are essential steps toward safeguarding the continent’s future.
As cholera and other infectious diseases continue to claim lives, the call to action is clear: Africa must invest in resilient health systems, and the global community must stand in solidarity to combat this pressing humanitarian crisis. The path forward demands bold leadership, sustained investment, and a collective commitment to health equity and security for all.
