Nigeria is facing significant outbreaks of cholera and diphtheria, with more than 65,000 suspected cholera cases recorded across 35 states and about 195 Local Government Areas. More than 10,000 confirmed diphtheria cases have also been reported in 2026.
The Director-General of the Nigeria Centre for Disease Control and Prevention (NCDC), Dr. Jide Idris, disclosed the figures in Abuja while providing an update on the country’s response to both outbreaks.
The NCDC has intensified disease surveillance and deployed National Rapid Response Teams to affected states, including Borno, which has recorded the highest number of cholera cases. Teams are investigating transmission sources and assessing water, sanitation and chlorination gaps.
To control cholera, authorities are bringing treatment closer to affected communities while expanding oral rehydration points, strengthening treatment centres, improving water chlorination and conducting oral cholera vaccination in high-burden areas.
The response to diphtheria is focused on reactive vaccination, early detection and treatment, particularly in Kano, Borno and Bauchi, where cases remain concentrated. Healthcare workers have also been urged to quickly identify, report and manage suspected cases.
The NCDC stressed that federal intervention alone cannot end the outbreaks. States and Local Governments must strengthen immunisation, improve access to safe water and sanitation, repair critical infrastructure and ensure communities have adequate treatment and rapid-response services.
Although declining cholera cases and improved survival rates are encouraging, the NCDC warned against complacency. Communities are advised to use safe water, practise good hygiene, prepare food safely and seek medical attention early. Anyone with frequent watery diarrhoea should begin oral rehydration immediately and visit a health facility, while parents and caregivers should ensure children are fully vaccinated against diphtheria.
