The World Health Organisation (WHO) has confirmed the closure of poliovirus type 2 outbreaks in five African countries following assessments that found transmission had been interrupted.

The countries are Burundi, Ghana, Guinea-Bissau, the Republic of Congo and Uganda, the WHO Regional Office for Africa said in a statement on Wednesday.

“Teams from the Independent Outbreak Response Assessment (OBRA) conducted separate assessments between January and June 2026, reviewing disease surveillance, laboratory and epidemiological data,” WHO noted.

WHO explained that the transmission was interrupted through targeted vaccination campaigns, epidemiological investigations and expanded environmental surveillance.

How countries stopped the outbreaks

In Burundi, where a circulating poliovirus type 2 outbreak was declared in March 2023, health authorities intensified routine vaccination and surveillance, with support from the Global Polio Eradication Initiative (GPEI).

WHO explained that through targeted vaccination campaigns, epidemiological investigations and expanded environmental surveillance, the transmission was interrupted.

Uganda also strengthened surveillance and outbreak response after poliovirus was detected in May 2024, while Ghana combined laboratory investments with disease surveillance and rapid outbreak response.

“Earlier this year, both countries upgraded their lab capacity, further strengthening their ability to detect and respond rapidly to poliovirus and other vaccine-preventable diseases,” WHO said.

In Guinea-Bissau, it added that targeted vaccination campaigns and enhanced surveillance focused on underserved populations have resulted in no poliovirus detections since July 2021.

The Republic of Congo strengthened surveillance and conducted multiple vaccination campaigns after virus detections, with the last detection reported in December 2023.

In his comments, WHO Regional Director for Africa, Mohamed Janabi, said the closures showed what could be achieved through national leadership, health workers, and collaboration among governments, communities, and partners.

“While this is an important milestone, it is not the end of the journey. Continued vigilance, strong surveillance and high immunisation coverage remain essential to protect children and prevent future outbreaks,” Mr Janabi was quoted to have said.

Nigeria maintains zero wild poliovirus

Nigeria has maintained zero transmission of wild poliovirus for six years, according to the WHO.

The country has also continued responding to circulating vaccine-derived poliovirus type 2 (cVDPV2), which remains a concern despite the absence of wild poliovirus transmission.

WHO recently highlighted the work of the National Polio Laboratory in Ibadan, which supports surveillance and rapid detection of poliovirus in the country.

According to the global body, the laboratory analyses more than 23,000 stool samples from 26 states and the Federal Capital Territory (FCT) each year and processes sewage samples from 60 wastewater surveillance sites.

It has also sequenced more than 1,000 poliovirus isolates since receiving WHO accreditation in February 2025.

WHO added that the laboratory is preparing for full accreditation by September 2026.

“With the Government of Nigeria and partners, WHO supports nationwide surveillance, vaccination campaigns and real-time data monitoring. These efforts help ensure every child is reached and every signal is investigated,” it noted.

Continued vigilance

Despite the latest achievement, the WHO warned that closing an outbreak does not eliminate the risk of future detections or reimportation.

The organisation pointed to the recent detection of poliovirus in Madagascar, after the country had previously declared its outbreak closed, as a reminder of the continuing risk.

WHO said countries must therefore maintain “high-quality surveillance and strong population immunity.”

Grace* never saw a state budget document, she never read a federal appropriation law or examined a budget implementation report.

She probably did not know that Nigeria’s HIV response was financed largely by international donors, or that governments at both the federal and state levels had, for years, pledged to assume greater responsibility for sustaining the programmes that kept people like her alive.

What she knew was simple: the community health worker who discreetly delivered her antiretroviral medicines stopped coming, the counselling sessions ended, and the confidential support that allowed her to avoid the crushing weight of stigma vanished.

Forced to collect her medication at a public treatment centre, Grace was recognised, felt exposed, and eventually withdrew from care.

Her experience raises the central question at the heart of this investigation.

As international donors began scaling back community HIV programmes, were governments, particularly in Rivers and Akwa Ibom, two of Nigeria’s highest HIV-burden states, prepared to fill the gap?

A PREMIUM TIMES investigation, based on official budget documents, budget implementation reports, government expenditure records and interviews with government officials, programme managers, health advocates and people living with HIV, found little evidence that they were.

Instead, the newspaper found a practice that raises troubling questions about responsibility and accountability.

Year after year, governments at both the state and federal levels approved budgets for HIV response. Each year, much of that money was not released.

The consequence is weakened health systems, interrupted community services, and patients who disappear from care without raising an alarm.

As donor support shrank, the expectation was that governments would step in and take ownership of the response.

However, PREMIUM TIMES did not see evidence that this happened in Rivers and Akwa Ibom. Instead, both states continued to make budgetary provisions for the HIV response while implementation lagged.

Budgets approved, funds withheld

Official budget documents and implementation reports reviewed by PREMIUM TIMES reveal a recurring pattern in both Akwa Ibom and Rivers states: governments consistently budgeted for HIV programmes, but the approved funds often failed to reach the agencies responsible for implementing them.

In Akwa Ibom, the State Agency for the Control of AIDS received capital allocations in every budget cycle reviewed by PREMIUM TIMES.

The agency was allocated capital budgets of N24.05 million in 2023, N10 million in 2024, N33 million in 2025 and N150 million in the 2026 budget.

The allocations covered activities central to HIV response, including the procurement of antiretroviral medicines, HIV rapid test kits, condoms and screening consumables.

On paper, the commitments suggested a government preparing to strengthen HIV services, although the approved funds were less than one per cent of the health sector’s total capital budget in each of the fiscal years reviewed by PREMIUM TIMES.

Conversely, budget performance reports reviewed by PREMIUM TIMES show that despite the budgetary allocations, the agency received no capital releases between 2023 and 2024.

The state has also not published the capital budget implementation report for 2025 or the first half of 2026, making it impossible for the public to independently determine whether subsequent releases were made and, if so, how the money was spent.

When contacted by PREMIUM TIMES, the Commissioner for Health, Ekem Emmanuel, said the agency received some support towards the end of 2025.

However, neither the commissioner nor the officials of the State Agency for the Control of AIDS provided documentary evidence of the amount released, the source of the funds, or the specific programmes financed.

However, the National Agency for the Control of AIDS (NACA), which conducts annual reviews of each state’s HIV investment through its state counterparts, told PREMIUM TIMES that Akwa Ibom had released only 1 per cent of its total 2024 and 2025 HIV appropriations.

Since the commissioner said funding was provided in 2025, the one per cent reported expenditure suggests that the oil-rich state spent no more than N330,000 out of its N33 million capital budget.

Across the border in Rivers State, PREMIUM TIMES found a similar pattern.

Official budget documents show that the state appropriated N180 million for HIV interventions in 2023 and another N230.66 million in 2024

The allocations covered procurement of HIV rapid test kits and consumables, community HIV counselling and testing, condom distribution and even the development of a state HIV anti-stigma law.

Yet the corresponding budget implementation reports indicate that none of those appropriations was released.

For 2025 and 2026, the Rivers State government has not published the approved fiscal documents necessary for independent scrutiny of HIV spending.

Repeated requests by PREMIUM TIMES seeking clarification from officials of the State Agency for the Control of AIDS yielded no explanation on whether subsequent releases had been made.

Interestingly, NACA told PREMIUM TIMES that Rivers State had zero release for HIV/AIDS during the period under review.

The findings indicate that while both states continued to budget for HIV response, they did not release the budgeted funds, at a time when international support was becoming increasingly uncertain.

Accountability beyond the budget books

The implications extend far beyond accounting records, as every unreleased allocation represents programmes that could not be implemented, outreach campaigns that never occurred, patients who were not traced after missing appointments and communities not reached with HIV testing and prevention services.

Uduak Nyaetok, the executive director of Milestone Initiative for Human Rights and Empowerment, an NGO that provides HIV response in the Niger Delta, told PREMIUM TIMES that HIV treatment does not begin with antiretroviral medicines.

Ms Nyaetok said it begins with prevention, especially by identifying people who do not know they are infected.

She noted that, “After testing, a good HIV response depends on counsellors who encourage frightened patients to start treatment.

“It relies on community workers who return to homes after appointments are missed and support groups that help people overcome stigma strong enough to keep them away from clinics.”

According to Ms Nyaetok, the withdrawal of donor-funded community services disrupted that chain of care.

Although some donor-supported HIV prevention activities, particularly case finding, have gradually resumed since June, she said the interruption exposed the consequences of governments failing to assume greater ownership of the HIV response.

“When the support was withdrawn, those who followed up on treatment were no longer there, and the viral suppression of the patients dropped. When they engage in risky behaviour, infections will definitely be high, and evidence abounds in data of new infections published.”

NACA agrees with her position. In response to a PREMIUM TIMES media enquiry, the AIDs agency said, “Programme data indicates that interventions implemented by the United States government-funded structures, particularly at the community level, experienced setbacks in coverage for case finding, pre-exposure prophylaxis uptake, and condom distribution.”

Ms Nyaetok argued that state governments must increase investment in community-based HIV services, especially in rural communities where many residents live far from health facilities.

For people like Grace*, the loss of community-based support was not simply the withdrawal of a donor-funded programme. It meant the disappearance of the very services that enabled them to remain in treatment, protect their privacy and live with dignity.

Federal spending tells similar story

The questions of accountability and responsibility are not confined to state governments. A PREMIUM TIMES review of federal financing trends between 2021 and 2026 also reveals a widening disconnect between budget approvals and actual spending.

In 2025, as uncertainty over international HIV funding intensified, the federal government approved N18.27 billion as capital expenditure for NACA, more than double the amount approved in 2024.

The increase suggested a recognition that domestic financing needed to grow as donor support became less certain.

Yet government expenditure records published on Govspend.ng, a portal that tracks and analyses federal government spending, showed that only 31.2 per cent of the approved capital allocation was cash-backed.

The following year, domestic investment weakened even further. Although the 2026 budget approved N13.97 billion as capital expenditure for NACA, government spending records show that only N36.68 million (0.3 per cent) of the approved allocation had been spent between January and May.

NACA told PREMIUM TIMES that the capital release had improved by June and that by mid-year, the agency had received 3.8 per cent of the approved allocation.

Even more disturbing was how the money was used between January and May. Of the amount expended, only N16.13 million went directly towards HIV response programmes, but only in Lagos State out of the 36 states of the federation.

By June, the agency said the total expenditure on the HIV response in Lagos had risen to N210 million. NACA, however, explained that the expenses were for two different constituency projects.

The remaining expenditure covered items such as cleaning services and staff welfare. N7.4 million was for the “Part payment for second quarter of cleaning service for NACA main building for November 2025 to January 2026,” while N13.12 million spent in April was for the supply of 364 bags of rice (25kg) and 152 cartons of vegetable oil for NACA staff.

Those figures raise difficult questions about Nigeria’s preparedness to sustain HIV services as international partners gradually reduce direct programme implementation.

The disconnect further threatens one of the foundations of global HIV control. The UNAIDS 95-95-95 targets require that 95 per cent of people living with HIV know their status, 95 per cent of those diagnosed receive sustained treatment, and 95 per cent of those receiving treatment achieve viral suppression. But meeting those targets requires far more than purchasing medicines.

“It demands sustained investment in community testing, patient follow-up, laboratory systems, adherence counselling and community support,” Ms Nyaetok said.

She said this is the very intervention that has suffered most from shrinking donor assistance.

For Grace’s* family, those gaps not filled by domestic financing led to a painful experience. They are pained that when the support system vanished, nobody replaced it quickly enough.

However, NACA told PREMIUM TIMES that they are on top of the response effort by improving on the National Domestic Resource Mobilisation and Sustainability Strategy (2021-2025), which sets out key objectives and innovative approaches to address the domestic resource gap for HIV prevention and treatment interventions.

It noted that the federal government had launched the HIV Trust Fund of Nigeria under the Nigeria Business Coalition Against AIDS, with N10.7 million mobilised in 2024.

NACA added “The Government of Nigeria recognises that the integration of HIV treatment and related health intervention into State Health insurance Schemes will ensure sustainability of funding for HIV treatment and prevention services. To facilitate this, NACA, the National Health Insurance Authority along with partners, developed the National Blueprint for Integration of HIV into State Health Insurance Schemes in 2020.

“Nigeria has moved towards sustainable domestic financing by leveraging financial protection schemes such as the Basic Health Care Provision Fund, State Health Insurance Schemes, and Private Health Insurance to avert out-of-pocket payments for PLHIV beneficiaries at the point of care.

“HIV testing is now included in benefit packages at the national and subnational levels, thus paving the way for the inclusion of ARV treatment in the near future. The benefits also cover baseline and treatment monitoring investigations and management of opportunistic infections. Efforts are ongoing to target the enrolment of PLHIV into financial protection schemes at the state level.”

NACA said that to address the funding gap, the federal government injected $200 million (about N260 billion) into the federal budget in 2025. However, as shown earlier, PREMIUM TIMES found that only N5.7 billion was spent by NACA.

Smaller epidemics, stronger investments

Perhaps one of the most thought-provoking findings of PREMIUM TIMES’ investigation is the contrast between Nigeria’s highest HIV-burden states and some of its lowest.

Rivers has the largest population of people living with HIV in Nigeria, while Akwa Ibom consistently ranks among the states with the highest burden. Conventional public health planning would suggest that both should rank among the country’s strongest domestic investors in HIV programmes.

However, financial records tell a different story. While Rivers and Akwa Ibom struggled to convert budget promises into actual spending, several states with significantly lower HIV burdens continued making measurable domestic investments.

In Kwara State, where an estimated 20,259 people are living with HIV, about one-eighth of Akwa Ibom’s burden, the government spent N608.63 million on HIV interventions in 2024, according to a budget implementation report reviewed by PREMIUM TIMES.

Between January and September 2025, the state released another N132.16 million as counterpart funding for Global Fund-supported HIV and malaria programmes.

Its 2026 budget goes even further, earmarking N8.29 billion for Global Fund-supported health interventions, including HIV, as part of efforts to strengthen domestic financing.

The contrast extends beyond Kwara. Zamfara, one of Nigeria’s lowest HIV-burden states, spent N3.42 million directly on HIV programmes in 2025, despite having an estimated 13,253 people living with HIV.

Yobe, which has the country’s lowest HIV burden, also recorded direct spending of N500,000 on HIV interventions in 2025.

The comparison is not intended to suggest that those states have solved their HIV financing challenges. However, it illustrates that domestic investment is possible even where the epidemic is far smaller.

That reality makes the experience in Rivers and Akwa Ibom more difficult to explain. Both states rank among Nigeria’s most economically strategic sub-national governments, benefiting from substantial oil revenues and historically receiving some of the country’s largest allocations from the Federation Account.

Akwa Ibom currently ranks as the country’s fourth-largest Federation Account Allocation Committee (FAAC) recipient. As PREMIUM TIMES reported earlier this year, Governor Umo Eno’s administration generated N2.53 trillion in revenue within its first 32 months in office.

Although Rivers State has not published its fiscal books since 2025, the oil-rich State ranks second among FAAC revenue earners in the country.

Regardless, interviews with health workers, advocates and people living with HIV show that as donor-funded programmes contracted, domestic financing failed to expand at the pace required to protect the gains made over two decades.

For people living with HIV, the difference between a budget approved in a government document and money released into the health system is measured in whether a counsellor notices when a patient misses an appointment, whether a community worker quietly delivers medicines to someone too afraid to be seen at an HIV clinic, whether a support group remains open for an adolescent struggling with stigma, or whether a newly infected person is diagnosed before unknowingly transmitting the virus to someone else.

Those are the investments that sustained Nigeria’s HIV response for years. They are also the investments that many patients and advocates told PREMIUM TIMES have steadily faded just as governments were expected to assume ownership of the response.

With the global target of ending AIDS as a public health threat by 2030 approaching, NACA insists that Nigeria is well-positioned to achieve the targets by 2030, but gives an important warning: “The risks that could hinder the attainment of the goals are related to funding instability from government and donor partners.”
