Katsina State has vaccinated more than 150,000 people within five days of launching an emergency vaccination campaign as authorities intensify efforts to contain a diphtheria outbreak affecting communities across 29 local government areas.
The outbreak response combines emergency vaccination, case detection, treatment, contact tracing, isolation, infection prevention and community mobilisation, according to information released by the Katsina State Government.
The intervention follows the spread of suspected diphtheria cases across much of the state, with Funtua reported as the most affected area. Other local government areas with suspected cases include Kankia, Bakori, Katsina, Mashi and Daura.
The government said its response is focused on identifying affected communities, protecting people at risk and ensuring suspected cases receive medical attention early.
Over 150,000 Vaccinated in Five Days
The emergency reactive vaccination campaign began on August 25, 2026, targeting 15 high-risk wards across Bakori, Charanchi, Funtua, Mashi and Kankia local government areas.
By the fifth day of the campaign, 99,036 eligible persons had received the tetanus-diphtheria, or Td, vaccine, while 51,310 children had received the Pentavalent vaccine.
That brings the total number of vaccinations administered during the first five days to 150,346.
The campaign targets 114,570 children aged between six months and five years for Pentavalent vaccination and 146,075 people aged five to 15 years for the Td vaccine across the five implementing local government areas.
The state government said it has also secured an additional 650,000 doses of diphtheria-containing vaccines to expand protection in high-risk and affected communities.
Health officials are relying on vaccination posts, health facilities, house-to-house mobilisation and community engagement to increase participation, with traditional leaders and other local stakeholders also involved in the campaign.
How Katsina Is Coordinating the Response
The Katsina State Government has activated its emergency response structure, bringing together the State Emergency Preparedness and Rapid Response Team, the Katsina State Primary Health Care Agency and the Ministry of Health.
The state is also working with the National Primary Health Care Development Agency, the Nigeria Centre for Disease Control and Prevention and development partners.
According to the government, regular coordination meetings, surveillance activities, contact tracing and preventive treatment for people exposed to suspected cases are ongoing.
The response is designed to identify infections early and prevent further transmission within affected communities.
New Isolation Centres Expand Treatment Capacity
Beyond vaccination, the state has expanded its capacity to manage suspected and confirmed cases.
Three additional isolation centres have been established to complement an NCDC-supported isolation centre at the Federal Teaching Hospital in Katsina.
The government said essential medicines, medical consumables and infection prevention materials are being supplied, while case-management drugs are being positioned closer to affected communities.
Health workers are also receiving additional training in diphtheria surveillance and case management.
Surveillance teams are visiting communities and health facilities to identify suspected cases, trace contacts and update outbreak records. Preventive medicines are also being administered to contacts where required.
Early detection and treatment are particularly important in controlling the disease and reducing the risk of severe complications.
What Is Making the Outbreak Harder to Control?
Despite the scale-up of the response, health authorities face several challenges.
According to available reports cited by the Katsina State Government, low vaccination uptake in some communities and the late presentation of suspected cases at health facilities are complicating efforts to contain the outbreak.
Katsina’s international border with Niger Republic also presents an additional challenge for disease surveillance and control.
Public cooperation, health officials say, will therefore remain critical to the success of the response.
Parents and caregivers are encouraged to ensure eligible children receive recommended vaccines and to seek medical attention promptly when symptoms appear.
What Are the Symptoms of Diphtheria?
Diphtheria is a serious bacterial infection that can affect the throat, tonsils and nose and may lead to severe complications if not treated quickly.
Symptoms highlighted by the state government include:
- Sore throat
- Fever
- Difficulty swallowing
- Difficulty breathing
- Swelling of the neck
- A thick greyish or whitish membrane in the throat, tonsils or nose
Anyone experiencing these symptoms should be taken to the nearest health facility immediately.
Suspected cases should not be managed at home while waiting for symptoms to worsen.
What Happens Next?
The Katsina State Government says it will continue to strengthen vaccination, disease surveillance, case management and routine immunisation as part of efforts to contain the outbreak.
The emergency campaign is expected to complement longer-term efforts to improve routine vaccine coverage and reduce the risk of future outbreaks.
With suspected cases now reported across 29 local government areas, the effectiveness of the response will depend not only on the availability of vaccines and treatment but also on how quickly suspected cases are identified, how effectively contacts are traced and whether communities continue to participate in vaccination and prevention efforts.
