A serious cholera outbreak has struck northern Nigeria, with Borno, Adamawa, and Kano states among the hardest afflicted. Cholera, an acute diarrheal disease transmitted by contaminated food and water, flourishes in regions with poor sanitation, and northern Nigeria has been particularly vulnerable due to long-standing infrastructure issues and recent climatic stressors.
The Nigeria Centre for Disease Control (NCDC) has reported a substantial increase in cholera cases in 2024, with Borno, Adamawa, and Kano states contributing significantly to the national total of over 10,800 suspected cases. These three states bear a double burden: high population density and poor sanitary infrastructure, which have aggravated the pandemic. Cholera’s impact on these states is both extensive and severe, with over 359 deaths documented across Nigeria, emphasizing the gravity of the crisis.

Borno has suffered various health issues, including cholera, as a result of persistent displacement caused by conflict. Many populations live in overcrowded camps, with little access to clean water and sanitation. This condition has made it harder to stop cholera spread because many residents rely on untreated water. Adamawa State has seen a surge in cases in recent months, with rural and conflict-affected communities particularly vulnerable. Open defecation and poor waste management lead to water contamination, which fuels cholera outbreaks. Kano, one of Nigeria’s most populous states, has failed to control the disease due to its densely populated metropolitan areas, which hamper waste management and water sanitation initiatives. Kano has reported an increase in instances, highlighting the need for prompt response.
Causes of this Outbreak
The cholera outbreak in these states raises numerous major challenges:
- Lack of Access to Clean Water: Many communities get their drinking water from open wells, rivers, and contaminated sources. In the absence of adequate boreholes or purified water, cholera bacteria spread quickly.
- Poor Sanitation and Hygiene: In rural and displaced populations, limited waste disposal infrastructure and extensive open defecation enhance the risk of cholera.
Climate Change Impacts: Climate unpredictability, notably floods during the rainy season, exacerbates the spread of waterborne diseases by contaminating drinking water. - Population Displacement: Conflict-related displacement, particularly in Borno and Adamawa, has resulted in densely crowded camps with poor sanitation, increasing the risk of cholera.
Response efforts
The NCDC, together with international health organizations including WHO and UNICEF, has initiated coordinated measures to address the outbreak, focusing on the following:
- Water and Sanitation Initiatives: The NCDC is working to install boreholes, provide water purification kits, and ensure clean drinking water in affected communities.
- Health Education: To prevent the spread of cholera, public health campaigns educate populations on the significance of hand washing, proper food handling, and boiling water before consumption.
- Rapid Medical Response: Hospitals in Borno, Adamawa, and Kano have been outfitted with rehydration therapy and antibiotics to treat cholera patients and reduce mortality.
In conclusion, to avoid recurrent outbreaks, substantial investments in water, sanitation, and hygiene (WASH) infrastructure are required. Strengthening local health systems, increasing surveillance, and providing emergency health resources can all assist in managing cholera and other waterborne infections. Furthermore, climate-resilient infrastructure will be crucial in mitigating the health effects of climate-related disasters in vulnerable places. The cholera outbreaks in Borno, Adamawa, and Kano highlight the critical need for long-term reforms in northern Nigeria’s water and sanitation systems. While present efforts focus on immediate containment, addressing the underlying reasons for cholera transmission will be critical to protecting public health in the long run.
