Diphtheria Outbreak Hits Kano Boarding School as 12 Cases Confirmed Among 2,000 Students
Diphtheria Outbreak Hits Kano Boarding School as 12 Cases Confirmed Among 2,000 Students
Health authorities in Kano State, Nigeria, have confirmed a diphtheria outbreak at a boarding school with more than 2,000 students, after testing found 12 cases of the vaccine-preventable infection.
The Kano State Centre for Disease Control, known as KNCDC, confirmed the outbreak at First Lady’s College, Mariri, in Kumbotso Local Government Area, and has launched an emergency response to contain it.
How the Outbreak Was Found
The agency received a report about suspected cases on Wednesday and immediately sent a Rapid Response Team to the school, according to KNCDC Director-General Professor Muhammad Adamu Abbas.
“We received the report on Wednesday and went there immediately for investigation and response aimed at curtailing further spread of the disease,” Abbas said.
Health workers tested 313 suspected cases at the school and confirmed 12. Teams searched the campus for more cases, gave medication to suspected contacts, and briefed students on the disease. One student with severe symptoms was taken to the Infectious Diseases Hospital in Kano, while the other confirmed cases are being treated within the school.
A Vaccine Shortage Is Slowing the Response
Abbas warned that the response is being held back by a shortage of diphtheria vaccines. “There is a need for massive vaccination in the school, which we presently do not have. We have to ask for more vaccines to administer to the students,” he said.
The shortage is part of a wider gap across Kano State. The agency has requested nine million doses for a state-wide mass immunization campaign but has received only about 500,000, according to local reports.
Background: Diphtheria Is Surging Across Northern Nigeria
Diphtheria is a bacterial infection that spreads through coughing, sneezing, and close contact. It can cause a sore throat, fever, and difficulty breathing, and in severe cases it can damage the heart and nerves. It is preventable with routine vaccination, which is why outbreaks are treated as a warning sign of gaps in immunization coverage.
Nigeria has recorded more than 10,000 confirmed diphtheria cases in 2026 as of late August, according to the Nigeria Centre for Disease Control, with Kano, Borno, and Bauchi carrying the heaviest burden. The school outbreak comes weeks after diphtheria reportedly killed about 50 people in Rano Local Government Area in October.

Why This Matters
A boarding school is one of the hardest places to contain an infectious disease. Students live, eat, and sleep in close quarters, so a single case can spread quickly through dormitories before symptoms are noticed. Without a mass vaccination drive, hundreds of students remain exposed while health workers can only treat cases as they appear.
The outbreak also matters beyond Nigeria. Vaccine-preventable diseases return quickly when immunization coverage slips, a pattern the United States has seen this year with measles. A second child died in a Wisconsin measles outbreak that has reached 649 cases, and the U.S. has now lost its measles elimination status after 10 deaths.
Latest Developments
The emergency response is continuing, with case searches and treatment of confirmed patients and their contacts. The KNCDC is seeking more vaccine for the mass campaign Abbas says the school urgently needs. No deaths have been reported in the outbreak so far.
Frequently Asked Questions
What is diphtheria?
Diphtheria is a bacterial infection of the nose and throat. It spreads through respiratory droplets and close contact, causing sore throat, fever, and difficulty breathing. It is preventable with routine vaccination.
How many cases have been confirmed at the Kano school?
Twelve cases were clinically confirmed out of 313 suspected cases tested at First Lady’s College, Mariri. One student with severe symptoms was admitted to the Infectious Diseases Hospital in Kano.
Why is there a vaccine shortage?
The KNCDC requested nine million doses for a state-wide campaign but has received only about 500,000, leaving the school without enough vaccine for a mass drive.
The Kano outbreak is a test of whether health authorities can vaccinate a crowded school before a dozen cases become many more. For now, the response depends on the vaccine supplies officials are still waiting for.
