Cholera Outbreak in Nigeria: A Persistent Public Health Crisis
Cholera remains a significant public health challenge in Nigeria, with devastating consequences for communities across the country. Between 2020 and 2024, a total of 4,778 people died from the disease, according to data from the Nigeria Centre for Disease Control and Prevention (NCDC). The situation has not improved in recent months, as over 300 deaths have been recorded this year alone.
Zamfara State Government recently reported 179 fatalities out of 12,052 suspected cases as of September 2025. Similarly, Bauchi State Deputy Governor Auwal Mohammed Jatau confirmed 58 new deaths from 258 cases across 14 local government areas just two weeks ago. Despite these grim statistics, billions of naira have been spent by the government and international partners to combat the disease. These funds include annual budgetary allocations, a $700 million World Bank loan for water, sanitation, and hygiene (WASH) facilities, $2 million in United Nations aid, and hundreds of thousands of Oral Cholera Vaccine (OCV) doses donated by UNICEF and WHO.
The NCDC data shows that cholera outbreaks have fluctuated over the years. In 2020, there were 3,513 suspected cases and 95 deaths (a 5.3% Case Fatality Ratio, or CFR). The following year saw a sharp increase, with 111,062 suspected cases and 3,604 deaths (a 3.2% CFR) across 33 states and the Federal Capital Territory. The disease is caused by the Vibrio cholerae bacterium and spreads through contaminated food and water, especially in areas with poor sanitation. Symptoms include severe dehydration, vomiting, and watery stools, which can be fatal if untreated.
In 2021, children aged 5 to 14 were most affected, with Bauchi, Jigawa, Kano, and Zamfara states accounting for 53% of all cases. The mortality rate dropped slightly in 2022 to 592 deaths (2.5% CFR) from 23,763 cases. However, the numbers rose again in 2023, with 3,683 suspected cases and 128 deaths (3.5% CFR), and in 2024, there were 10,837 suspected cases and 359 deaths (3.3% CFR) across 36 states.
Human Tragedies Behind the Statistics
The human cost of the outbreak is heartbreaking. Musa Aliyu lost his 5-year-old daughter, Muhammad Aliyu, after she contracted cholera at a wedding in Bauchi. Similarly, Fatima’s seven children became orphans when she died within hours of showing symptoms. Zainab Yusuf recounted how her family was infected, and one of her children succumbed to the disease.
Despite efforts to address the crisis, including the launch of the National Action Plan for Revitalizing the WASH sector in 2018 and securing a $700 million World Bank loan in 2021, progress has been limited. International partners such as the UN, WHO, and UNICEF have also provided critical support, including vaccines and medical supplies.
Expert Insights and Calls for Change
Experts emphasize that long-term solutions are needed to tackle cholera effectively. Professor Angela Oyo-Ita highlighted that access to clean water and public awareness are key drivers of the outbreak. Dr. Ekong Udoh noted that climate change has worsened flooding, leading to contaminated water sources.
The Federal Government launched the National Strategic Plan of Action on Cholera Control (NSPACC) 2025–2029, aiming to reduce cholera incidence and deaths by 90% and lower the CFR to below 1% by 2029. However, experts like Dr. Rotimi Adesanya and Prof. Agwu Nkwa Amadi stress the need for community participation, public-private partnerships, and sustainable WASH infrastructure.
Dr. Aminu Tukur Sulaiman urged communities to adopt better hygiene practices, such as handwashing and avoiding open defecation. He emphasized that controlling sanitation is essential to preventing the spread of cholera.
Conclusion: A Call for Collective Action
Nigeria must shift from emergency responses to long-term structural solutions to end the cycle of cholera outbreaks. This requires collaboration between the government, international partners, and communities. As the fight against cholera continues, the focus must remain on improving access to clean water, sanitation, and education to protect vulnerable populations and prevent future tragedies.
