NCDC Warns of Fresh Cholera Surge as 65,000 Cases Recorded in 35 States

The Nigeria Centre for Disease Control and Prevention (NCDC) has warned of a possible fresh surge in cholera cases as the country records more than 65,000 suspected cases across 35 states and about 195 Local Government Areas in 2026.

The agency said the decline in weekly cases should not create a false sense of security, noting that the ongoing rainy season, flooding, unsafe water and poor sanitation could trigger another wave of infections between late August and October.

NCDC Director-General, Dr Jide Idris, said cholera transmission remains active and urged governments and communities to sustain preventive measures.

Idris stressed that Nigeria cannot rely on treatment alone to defeat cholera, identifying unsafe water, open defecation, damaged water infrastructure and poor sanitation as major drivers of the disease.

He said the NCDC is working with state governments and partners on surveillance, laboratory support, case management, infection prevention, community engagement and deployment of rapid response teams to affected areas.

The agency said response measures include investigating sources of transmission, assessing water quality, chlorinating water, rehabilitating water sources, promoting hygiene and providing oral cholera vaccination in high-risk communities.

Meanwhile, the NCDC disclosed that more than 10,000 confirmed diphtheria cases have also been recorded this year.

Kano, Borno and Bauchi were identified among the states with a heavy diphtheria burden, with inadequate vaccination coverage contributing to continued transmission.

Idris urged parents and caregivers to ensure that children are fully vaccinated against diphtheria, while calling on state and local governments to strengthen immunisation programmes and provide resources for high-risk communities.

He also advised Nigerians to begin oral rehydration immediately when frequent watery diarrhoea occurs and seek medical attention without delay.

The NCDC boss called on traditional and religious leaders, civil society organisations and the media to help counter misinformation and promote preventive measures against both diseases.
