On the surface, Nigeria’s fight against tuberculosis appears to be holding steady. With a 94 percent treatment success rate and expanded diagnostic capacity, health authorities say progress is being made.
But beneath that progress lies a largely invisible threat, thousands of undiagnosed infections quietly spreading across communities.
In 2025 alone, Nigeria recorded 440,000 tuberculosis cases, according to the Minister of State for Health and Social Welfare, Iziaq Salako. Yet experts warn that this figure tells only part of the story.
The real burden, they say, is far greater and far more dangerous.
Tuberculosis, a highly infectious airborne disease, thrives in silence. A persistent cough dismissed as flu, unexplained weight loss, and night sweats are often ignored until it is too late.
For every confirmed case, health officials believe many more Nigerians remain undiagnosed, continuing to unknowingly transmit the disease.
“We have expanded access and improved diagnostic capacity, but undetected cases remain a serious concern,” Salako admitted during a ministerial briefing marking World Tuberculosis Day 2026 in Abuja.
This is the paradox of Nigeria’s TB response: success in treatment, failure in detection.
The Funding Gap: a Ticking Time Bomb
If undiagnosed cases are the silent driver of the epidemic, funding gaps may be the ticking time bomb that could undo years of progress.
Across the country, the tuberculosis programme is heavily dependent on international donors, a model now showing signs of strain.
According to the North-West Zonal Coordinator, Isiah Danssaallah, over 70 percent of Nigeria’s TB funding gap remains unmet.
Even more concerning, global health financing has been shrinking, with policy shifts dating back to the first administration of Donald Trump continuing to ripple through developing countries.
The implication is stark: Nigeria must now fund its own TB response or risk collapse.
When Funding Fails, Systems Break
The consequences of underfunding are not theoretical; they are already unfolding, as patients arriving at hospitals may find no drugs available, suspected cases go untested due to a lack of diagnostic kits, and treatment interruptions increase the risk of drug-resistant tuberculosis, ultimately leading to a rise in preventable deaths. “No TB programme can function without these essentials,” Danssaallah warned, stressing that delayed or inconsistent budget releases at the state level could ultimately determine who lives and who dies.
Niger State: A Warning Sign
In Niger State, the warning signs are already flashing red.
Health authorities say the state could face a full-blown TB crisis by June 2026 if urgent funding is not released.
Dr. Hananiya Dauda of the World Health Organisation revealed that only 8 percent of the expected 18 percent funding has been accessed.
“By June, we may not have commodities in the state,” he warned.
The numbers are sobering: a total of 127,410 presumptive cases were recorded, out of which 126,228 were tested, leading to the confirmation of 14,908 tuberculosis cases, but only 8,629 patients were successfully treated. Behind these figures are real people, many of whom may never complete treatment if essential medical supplies run dry.
The Dangerous Link: TB and HIV
Health experts are also raising alarms about the deadly intersection between tuberculosis and HIV/AIDS.
According to the Director of Public Health, Charles Nzelu, TB remains one of the leading causes of death among people living with HIV.
This dual burden complicates treatment and increases mortality risks, making integration of TB and HIV services not just necessary but urgent.

To address these challenges, the government has launched the Multisectoral Accountability Framework for TB (MAF-TB), a system designed to track commitments and improve coordination.
Coordinating Minister of Health, Muhammad Pate, says the goal is to move away from fragmented, donor-driven interventions toward a coherent, nationally owned response.
But experts caution that frameworks alone cannot save lives.
Without timely funding, efficient procurement systems, and strong political will, even the best-designed strategies risk becoming mere paper promises.
Communities: The Missing Link
For many experts, the solution lies beyond government offices and policy frameworks within communities themselves.
Queen Ogbuji-Ladipo of the Stop TB Partnership stresses that ending TB requires grassroots ownership.
From improving awareness to encouraging early testing and reducing stigma, communities play a critical role in identifying the “missing” cases.
Because in the fight against TB, the most dangerous patient is the one who doesn’t know they are sick.
Nigeria has committed to eliminating tuberculosis by 2030 in line with global targets. But current realities suggest the country is at a crossroads.
On one path lies increased domestic funding, stronger health systems, integrated care, and community-driven detection; on the other are drug shortages, diagnostic gaps, rising undetected infections, and a resurgence of drug-resistant tuberculosis, with the difference between both paths not in ambition, but in action.
Tuberculosis is curable. It is preventable. And yet, it continues to kill not because solutions do not exist, but because systems fail to deliver them in time.
Nigeria’s TB story is no longer just about disease control. It is about governance, financing, and accountability.
The warning has been issued. The data is clear. And the stakes could not be higher.
If the “missing thousands” remain undetected, Nigeria risks facing not just a public health challenge but a full-scale health emergency hiding in plain sight.
