The 20-year-old initially thought little of it, but the pain was soon followed by fever, vomiting and frequent watery stools. Within hours, his condition had deteriorated.

It was in August 2025, during a cholera outbreak in Bukkuyum Local Government Area of Zamfara State, that Saidu fell ill. He and his family had fled bandit attacks in Dan Bago village of the same LGA and sought refuge in Bukkuyum town. 

Like thousands of residents displaced by years of insecurity in the state, the family had already lost the stability of a home. Now, as Saidu became increasingly ill, they faced another problem: getting medical care.

His parents first tried what they could afford. They mixed a local herbal with water, hoping it would improve his condition. It did not.

The family eventually took Musa to the Orphan and Less Privileged Clinic (OLPC) in Bukkuyum town, where he was diagnosed with cholera.

But reaching a health facility did not immediately end their difficulties.

The clinic was struggling with an influx of cholera patients. Only three health workers were on duty, while essential medicines were unavailable.

The outbreak had spread, and many residents affected were brought to the same facility, while others sought treatment elsewhere because of shortages of staff and space.

For displaced families such as Saidu’s, the outbreak exposed a problem that went beyond cholera.

Years of insecurity have weakened the local health system. Health workers are forced to avoid some rural communities. With access to healthcare, safe water and disease surveillance now disrupted, many communities become vulnerable during disease outbreaks. 

When insecurity becomes a health crisis

Zamfara is one of the states hardest hit by the insecurity that has spread across north-western Nigeria over the past decade.

What began largely as conflict between farmers and herders has evolved into organised violence by armed groups commonly referred to as bandits. Communities are constantly attacked, residents killed or abducted and thousands forced to flee their homes.

The armed groups have also imposed levies on some farming communities, stolen livestock and harvests and carried out kidnappings for ransom.

Data obtained from the Mass Atrocities Tracker show that 28,974 people were killed across Nigeria between 2021 and 2025. Borno in the northeast recorded the highest number, with 4,539 deaths, followed by Zamfara with 3,936 and Kaduna with 2,811.

The data on abductions shows Zamfara recorded the highest during the same period, with 5,447 people kidnapped, while Kaduna recorded 4,050 and Niger 3,331.

But deaths, abductions and displacement are only some of the consequences.

In Bukkuyum LGA, access to healthcare has become another casualty of insecurity. Residents and health workers told The ICIR that some communities have been deserted, while health workers have stopped providing services in areas they consider unsafe.

Reports in 2025 indicated that only about 200 of Zamfara’s more than 700 Primary Healthcare Centres (PHCs) were functional, with persistent insecurity blamed for the closure or abandonment of many facilities.

For residents of affected rural communities, the closures mean illness can require travelling several kilometres, sometimes through unsafe areas, to reach a health worker.

The risks for people displaced by violence are compounded by overcrowding, poor sanitation, poverty and limited access to safe water.

During a cholera outbreak, those conditions can become deadly.

Displaced, then confronted by cholera

Buba Muhammad had already fled his home in Sadawa with his family because of repeated bandit attacks when his son began vomiting and passing frequent watery stools.

The 40-year-old farmer and his family were living as displaced persons in Bukkuyum, where several families shared limited space and sanitation facilities.

Muhammad immediately tried to find medical help, but there was no functioning health facility close to his location.

“My first attempt when my son was affected was to go to a hospital, but there was no facility nearby,” he said. “I had to take him to a medicine shop.”

The medicines he obtained did little to improve the boy’s condition.

As the vomiting and diarrhoea continued, Muhammad decided to take him to General Hospital Bukkuyum, the nearest facility where he believed the child could receive appropriate treatment.

But another problem awaited them.

The hospital was struggling with an influx of patients from communities affected by the outbreak.

“We didn’t receive the proper care we expected immediately because there were not enough staff,” he recalled.

“There was no bed space. We even kept our patient on the floor before a staff member later found us a bed.”

The illness also placed a financial burden on a family already displaced by insecurity.

Muhammad said they spent heavily on transportation and medicines, including prescribed drugs they had to buy outside the hospital.

“The only solution to ease the hardship of such unwanted incidents or outbreaks is to provide facilities in our local communities,” he said.

But he quickly added that restoring healthcare without addressing insecurity would leave an essential part of the problem unresolved.

“We need security in our locations because we are not safe; there are attacks every day and night in our locations. The government needs to double its efforts to end the problem,” he said. 

A preventable disease finds fertile ground

Cholera is an acute diarrhoeal disease caused by consuming food or water contaminated with the bacterium Vibrio cholerae. Without prompt treatment, severe cases can lead to rapid dehydration and death.

It is also largely preventable through access to safe water, adequate sanitation and good hygiene, while prompt administration of oral rehydration solution and other appropriate treatment can substantially reduce deaths.

Yet cholera has repeatedly affected communities in Zamfara State.

In 2023, a World Health Organisation (WHO) report recorded 907 suspected cholera cases in the state, representing about 28 per cent of Nigeria’s suspected cases during the period covered.

The state was affected again in 2024. WHO reported more than 700 cases and over 30 deaths across Zamfara and neighbouring Sokoto during the period covered by its report.

By 9 July 2025, Zamfara had recorded 1,619 suspected cases, six confirmed cases and 31 deaths across 12 of its 14 local government areas, according to a UNICEF situation report.

UNICEF said suspected cases increased by 30 per cent within one week, with children and young people accounting for 62 per cent of reported cases.

The crisis continued.

In August 2025, an outbreak in communities in Bukkuyum LGA killed at least eight people and affected more than 200 across 11 communities, according to residents and local officials cited by Reuters.

For residents already dealing with displacement, unsafe water and weakened healthcare services, the outbreak exposed how insecurity can magnify an otherwise preventable public health emergency.

The Nigeria Centre for Disease Control and Prevention (NCDC) identifies unsafe water, inadequate sanitation, and poor hygiene as major drivers of cholera transmission.

In parts of Bukkuyum LGA, insecurity has made it harder to address these risks. Residents have been displaced into congested settlements, some health facilities are non-functional, and health workers say reaching remote communities for surveillance and other services can be dangerous.

For rural residents, treatment can mean a dangerous journey.

In Masu community, Salihu Bello returned home one afternoon to find his two sisters seriously ill.

“They had stomach pain, and became very weak,” he recalled. “Later we realised it was cholera.”

With no health facility in the community, the family initially relied on local remedies.

But the sisters’ condition worsened. Seeking treatment meant undertaking a difficult journey to Bukkuyum town. To reach the town, they would have to cross a river, a challenging ordeal now more dangerous due to insecurity.

“Sometimes health workers used to come to our community, but because of security problems they stopped,” Bello said.

As night fell, the family began the trip. Fear of bandits lingered throughout the journey, but Bello said concern for his sisters outweighed their worry.

“At that moment, we were not thinking about insecurity. We only wanted to save them. It took about three hours before we received attention because we arrived very late at night,” he said.

When a health worker finally prescribed medicines, Bello had to wake a medicine vendor before dawn to get them.

His sisters remained under observation for about 24 hours before their conditions improved.

That experience, according to Bello, showed the cost of having no functioning healthcare facility nearby.

“If we have a health facility in our community, things will be easier, considering how quickly the disease can affect the human body,” he said.

“Before a patient from our community gets to the hospital, they suffer a lot. Having our own health facility would make access to treatment much easier.”

But the health facility is only part of what residents say they need.

In Masu and other communities around Bukkuyum, preventing cholera begins with something even more basic: clean water.

Unsafe water keeps the risk alive

In communities around Bukkuyum, residents said access to clean water remains a major challenge.

Some depend on streams for drinking, cooking and other household needs. In Dan Bago, residents said they share the same water source with cattle.

For a community already vulnerable to cholera, such conditions increase the risk of transmission.

Nigeria’s 2021 Water, Sanitation and Hygiene National Outcome Routine Mapping (WASHNORM) report highlighted the scale of the country’s water and sanitation challenge. 

Based on a survey of more than 24,600 households, the report estimated that approximately 179 million Nigerians, about 87 per cent of the population, lacked access to safely managed drinking-water services.

The situation was particularly difficult in northern Nigeria. The Northeast had the lowest access rate at just two per cent, compared with 29 per cent in the Southwest, which is the highest.

Although 67 per cent of the population had access to basic water supply services, about a quarter of Nigerians still relied on unimproved or surface water sources.

Muhammadu Sadawa, a community leader, said insecurity has worsened the situation by forcing residents from their homes and concentrating displaced families in already strained settlements.

“Most of our people left the community because of banditry. Where we are now living is too congested and very dirty. That congestion helped the disease spread among us,” he said. 

Sadawa explained that access to healthcare had also deteriorated.

“We have a health facility, but it is not in existence. There are no staff, no drugs. The building is dilapidated and almost collapsing,” he said.

During the cholera outbreak, residents therefore had to look elsewhere for treatment.

He said some families struggled to access care before outside assistance arrived, while others faced delays because of distance and the cost of treatment.

“Many people died, and it took a long time before we received any intervention. Some people were treated, some were not. I have a relative who spent over N50,000 on treatment. Many families went through the same thing,” he said.

He estimated that more than 50 people in and around his community were affected during the outbreak, with some becoming ill in displacement settlements before being taken to Bukkuyum town for treatment.

Health workers struggle to reach vulnerable communities

At General Hospital Bukkuyum, Abdullahi Salihu, a health worker, remembers the pressure as cholera patients arrived from communities across the local government area.

“At the time of the outbreak, it was very tense and hectic considering how patients were being brought to the hospital,” he said.

“Some survived, some were quarantined, and unfortunately some died.”

According to Salihu, insecurity complicated the response. Patients who could leave affected communities were brought to the hospital. But health workers had limited options for people trapped in settlements that were difficult or unsafe to reach.

“As health workers, we faced a lot of challenges because of insecurity,” he said.

“Some people managed to bring patients from their communities because they had no other option. But for those who could not come out, there was little we could do for them.”

Salihu said government officials, politicians and humanitarian organisations provided intravenous fluids, antibiotics, rehydration supplies and other support during the outbreak.

But insecurity was not the only challenge.

“Most of them were displaced from their communities with nothing to eat,” he said. “Then the outbreak added another difficulty to their lives.”

Zaharadeen Abdullahi, a health worker at the Women and Children Welfare Clinic in Bukkuyum, also described insecurity as a major obstacle to preventing and responding to outbreaks.

“We have services, vaccinations and awareness programmes, but because of security challenges many health workers cannot reach vulnerable communities.”

Some affected settlements are more than 10 kilometres from health facilities, Abdullahi said. In some areas, he said, insecurity has also limited the transportation options. 

“Some communities cannot use motorcycles because of security threats,” he said. “People have to walk long distances or use donkeys. Because cholera requires urgent treatment, these delays can lead to deaths.”

He said displacement had created additional risks.

“Most of the affected people are internally displaced persons living in congested conditions,” Abdullahi said. “Many rely on unsafe water sources, and stagnant water is still being used for drinking and household activities.”

He acknowledged support from the Zamfara State government, UNICEF and other organisations during the outbreak but said greater investment was needed in health facilities, medical supplies and outreach to vulnerable communities.

Insecurity weakens disease surveillance

Shakir Balogun, an epidemiologist and Resident Advisor at the Nigeria Field Epidemiology and Laboratory Training Programme (NFELTP) at the African Field Epidemiology Network, explained that  Zamfara’s recurring cholera outbreaks go beyond a disease problem, but expose weaknesses in healthcare access and disease surveillance created or worsened by years of insecurity.

“When insecurity makes communities difficult to reach, children can be missed by immunisation programmes, cases of Acute Flaccid Paralysis (AFP) can escape surveillance, and cases of acute watery diarrhoea can similarly go undetected or reach treatment late,” he said.

“The pathogen changes; the health-system vulnerability does not.”

He said these weaknesses were particularly evident during the 2025 cholera outbreak.

According to him, the African Field Epidemiology Network (AFENET), with technical and financial support from the US Centres for Disease Control and Prevention, had deployed eight Field Epidemiology Training Programme residents and a graduate to support Zamfara’s response between 11 September and 2 October 2025. 

The team worked with state authorities in four high-burden local government areas.

Balogun explained that the response identified cases in inaccessible and insecure settlements, adding that it also identified under-reporting linked partly to weak active case searches and insecurity, as well as delayed reporting and incomplete records.

He said other challenges included transporting stool samples to the state reference laboratory, shortages of essential supplies outside initially prioritised LGAs and inadequate personnel in some health facilities.

The findings suggest that insecurity can affect almost every stage of outbreak control, from identifying a sick person and reporting a suspected case to testing samples and getting treatment to patients.

The epidemiologist said strengthening community-based surveillance could help close some of those gaps.

Trusted residents and community structures, he said, can help identify and report suspected cases when conventional health teams cannot safely reach affected settlements.

Treatment also needs to be brought closer to vulnerable communities.

“If insecurity means a severely ill patient has to travel several hours or cross an unsafe area before receiving ORS or intravenous fluids, geographical access itself becomes a determinant of survival,” he said.

He recommended establishing oral rehydration points and treatment units close to vulnerable communities, backed by reliable referral systems for patients who develop severe disease.

Authorities should also use surveillance and previous outbreak data to identify communities repeatedly affected by cholera and position essential supplies there before outbreaks escalate, he said.

“You do not want to begin moving ORS, IV fluids, chlorine and other essential supplies into a hard-to-reach community only after an outbreak has accelerated,” Mr Balogun said.

“We should use surveillance and historical data to identify recurrent hotspots and position supplies before the rainy season.”

Treatment alone will not stop recurring outbreaks

Bringing treatment closer to affected communities could save lives, but Mr Balogun said it would not eliminate the conditions that allow cholera to return.

He said safe water and sanitation remain fundamental.

Vaccination and effective case management can reduce infections and deaths during outbreaks, he said, but stressed that communities will remain vulnerable if they continue to depend on unsafe water and inadequate sanitation.

Balogun recommended strategic use of oral cholera vaccines among high-risk populations and in communities with recurring outbreaks, particularly where insecurity makes immediate improvements to water and sanitation infrastructure difficult.

But he cautioned against treating vaccination as a replacement for those investments.

“Vaccination is an additional layer of protection, not a substitute for water, sanitation, surveillance and access to treatment,” he said.

Government turns to community-based response

The Zamfara State government said it has adopted community-based measures to maintain disease surveillance and provide basic cholera support in areas where insecurity makes conventional healthcare difficult.

The state Ministry of Health, working with the World Health Organisation (WHO) and other partners, said it has also begun developing a Multi-Hazard Incident Action Plan to strengthen preparedness and response to public health emergencies, including cholera.

Ahmad Muhammad, the Zamfara State epidemiologist, acknowledged the difficulty in reaching communities affected by insecurity but said one strategy is to identify community health workers from insecure areas, bring them to safer locations for training and then send them back to support residents.

He said trained workers are provided with available medical supplies and asked to report suspected cases so health officials can track whether infections are increasing or declining. 

According to the epidemiologist, the approach forms part of the state’s risk communication and community engagement strategy, under which people with health-related roles in affected communities are trained to support local outbreak response.

“Patients who can safely be evacuated are moved to accessible areas for further treatment, including general hospitals and the treatment centre at the Infectious Disease Hospital in Gusau,” he added, attributing the state’s reduced cholera burden in 2026 compared with the previous year to interventions including community sensitisation, improved hygiene, and oral cholera vaccination.

He said the government had also intensified water, sanitation and hygiene interventions, including measures to reduce open defecation.

“So I think those strategies have really gone a long way in mitigating the impact,” he said.

But for residents of communities where health facilities remain closed or poorly equipped and safe water remains difficult to access, the conditions that make cholera dangerous have not disappeared.
