4.36 million people targeted for river blindness treatment in Nigeria

Nigeria is launching a mass drug campaign against river blindness to eliminate onchocerciasis by 2030 through ongoing treatment and community engagement.

A mass drug campaign against river blindness (onchocerciasis), a parasitic disease that can cause lifelong skin damage and blindness, is underway across 23 local government areas in Oyo State in Nigeria, targeting more than 4.36 million people.

The campaign is part of Nigeria’s wider drive to eliminate neglected tropical diseases by 2030, a target that hinges on sustained, high-coverage treatment in endemic communities over many years.

Onchocerciasis, also called river blindness, spreads through repeated bites from infected blackflies that breed near fast-flowing rivers and streams. The parasite, Onchocerca volvulus, produces larvae that migrate through the skin and eyes, triggering intense itching, skin disease, and, in some cases, permanent blindness.

Community-wide distribution of ivermectin

Public health programmes typically respond with community-wide distribution of ivermectin, a medicine that kills the larval stage and reduces transmission when delivered repeatedly at scale. Because ivermectin does not kill adult worms, health authorities rely on repeated treatment rounds for years to outlast the parasite’s lifecycle and interrupt spread.

In Oyo State, the effort is supported by Christian Blind Mission (CBM), through our Reaching the Last Mile Project. The group is working with the Oyo State Ministry of Health to support drug distribution and the systems around it, including planning, training, supervision, and data checks.

A campaign of this size depends on logistics and trust as much as medicine. Organisers describe a full delivery cycle that began with microplanning and training and moved through community mobilisation, distribution, monitoring, and post-treatment validation. The goal is straightforward, reach as many eligible people as possible, and record who received treatment with enough accuracy to guide the next round.

The early phase focused on preparation at state and local levels. A three-day training brought together monitoring and evaluation staff, state and local coordinators, primary health care leaders, and data managers. The group reviewed local microplans and the operational approach, then trained across supply chain management, training cascades, drug administration, reverse logistics, social mobilisation, supervision, and data management.

The campaign also opened a wider question that follows most disease-control efforts in Nigeria, who pays for the long haul.

State government directs annual NTD allocations from LGAs starting in 2026

At a high-level meeting in Oyo State, CBM representatives, led by Dr. Joseph Kumbur, its technical specialist for neglected tropical diseases, met with senior state officials and partners including the World Health Organization, UNICEF, and Evidence Action. The discussions centred on domestic resource mobilisation and how the state will keep the programme running as donor models shift.

According to participants, donor expectations include the start of counterpart funding from 2027, a timeline that pushes states to move from project-based support to routine budget lines. The meeting pressed for a sustainability approach that sits inside the state budgeting process, rather than depending on ad hoc releases.

The state’s top administrative office responded with a concrete directive. The Secretary to the State Government instructed local government areas, through the Local Government Service Commission, to provide a budget line annually for neglected tropical disease activities starting in 2026.

Frontline health workers prepare for safe delivery

Frontline health workers received additional training on correct administration, record keeping, and clear communication. Trainers also drew a sharp line between this campaign and other public health drives, an approach designed to reduce confusion and improve acceptance at community level.

For Nigeria, the stakes extend beyond a single treatment round. Onchocerciasis control demands sustained coverage over time, and elimination efforts falter when funding gaps interrupt campaigns or when data quality obscures true reach.

The Oyo State campaign now becomes a test of whether stronger planning and a clearer financing path can protect that continuity. If the annual local government allocations materialise in 2026 and the state builds a durable plan ahead of the 2027 counterpart funding expectations, health officials say the programme will stand on firmer ground for the long cycle required to stop transmission.

For communities along river basins, the measure of success will be simple, fewer people living with relentless itching and preventable vision loss, and fewer places where the parasite still circulates.
