Cholera Outbreak in Cameroon’s Far North: A Consequence of Climate Change
In Cameroon’s Far North, a cholera outbreak has significantly impacted local communities, exacerbated by severe climate change effects. Since November 2024, 127 cases have been reported, emphasizing the urgent need for improved sanitation, health education, and community engagement to combat waterborne diseases. Flooding and drought cycles contribute to the region’s vulnerability, necessitating an integrated public health and climate response.
In Cameroon’s Far North, a cholera outbreak has emerged amid the damaging effects of climate change, deeply affecting local communities. Abba Gana’s family from Douggoï experienced this firsthand when all three members contracted the disease in rapid succession. Habiba, one of Gana’s wives, described her stomach pains and subsequent diarrhoea that led her to the hospital, illustrating the epidemic’s severe impact on daily life.
The outbreak began on November 8, 2024, when four patients from one family were admitted with severe symptoms. Over the following weeks, the number of affected individuals rose to 127, with two reported deaths. Although the outbreak reportedly slowed by year’s end, the trauma of the experience remains vivid in the memories of victims and their families.
The region suffered from severe flooding between August and October 2024, affecting 459,000 people and increasing the risk of cholera by contaminating water sources. Poor sanitation and unsafe drinking water create an environment ripe for disease transmission, especially as the region also hosts many refugees and internally displaced persons.
Cholera outbreaks are not new to the Far North, which has faced recurring epidemics every two years since 2010. Eugene Nforngwa, a climate change expert, identified the cyclical relationship between the climate, water resources, and public health vulnerabilities as the root cause of frequent cholera cases in this fragile region.
Flooding causes extensive damage and contaminates water supplies, while subsequent droughts lead to water shortages, increasing reliance on unsafe sources. Patrick Mbomba, the Deputy Director-General of Cameroon’s National Observatory on Climate Change, noted that this interplay between flooding and drought creates conditions conducive to cholera outbreaks.
In response, community health workers have been deployed across Maroua to educate the public on cholera prevention. They distribute free sanitation products and conduct awareness visits while addressing issues like waste disposal. The lack of adequate resources for sanitation and debris removal remains a significant concern in these efforts.
Public health officials have focused on educating households about water purification techniques, where they distribute tablets for water treatment. They also recommend alternative methods like boiling water to ensure safety. Integrated efforts involving local authorities are key to addressing the cholera threat.
To combat cholera effectively, a multisectoral approach is essential, addressing health and climatic factors. Eugene Nforngwa advocated for sustainable health responses, emphasizing the need for surveillance systems, rapid response mechanisms, and resilient water supply infrastructures. Community involvement in adaptation strategies ensures that localized needs are addressed adequately.
Promoting hygiene education can further reduce cholera transmission risk following flooding events. By fostering community engagement in decision-making, localities can be better prepared for the impacts of climate change and water-related diseases, thereby improving public health resilience.
Cholera is an infectious disease that is primarily transmitted through contaminated water. In regions like Cameroon’s Far North, cholera is exacerbated by climate change factors such as irregular rainfall, increasing flooding events, and prolonged droughts. This creates a cycle where contaminated water sources and inadequate sanitation systems contribute to outbreaks, particularly in areas with high numbers of internally displaced individuals. Understanding the interactions between climate phenomena and public health vulnerabilities is vital for developing effective response strategies.
The cholera outbreak in Cameroon’s Far North exemplifies the urgent need for integrated health and climate response strategies. By addressing sanitation issues, improving water quality, and engaging local communities, the region can enhance its resilience to cholera and other waterborne diseases exacerbated by climate change. Collaborative efforts involving public health education and infrastructural improvements are essential to mitigate the impacts of future outbreaks.
