When cholera strikes vulnerable communities, the true danger rarely begins in the hospital ward.
Instead, it breeds quietly in unsafe drinking water, broken sanitation systems, and crumbling infrastructure that leave families exposed to infection long before the first patient falls ill.
Across Borno, Bauchi and Plateau States, recent outbreaks have exposed a stubborn public health reality: treating patients can save lives, but preventing transmission requires sustained investment in water, sanitation and hygiene nationwide.
In Borno, where displacement and overstretched infrastructure have intensified vulnerabilities, communities say emergency interventions helped contain outbreaks, but fear that gains could disappear without continued government and humanitarian support over time.
The experience of Mashamari Ward in Jere Local Government Area illustrates the challenge.
Its residents recently endured a severe cholera outbreak that threatened thousands, including many internally displaced people recently.
Village Head Malam Aisani Abba said the community, estimated to have more than 120,000 residents, faced intense pressure on healthcare services, water supplies, sanitation facilities and other essential amenities daily.
He commended the Borno Government under Gov. Babagana Zulum, local authorities and humanitarian organisations for responding promptly, saying coordinated action helped prevent the outbreak from becoming even more devastating further.
Organisations including International Alert and Voluntary Aid Initiative supported affected households with hygiene kits, sanitation facilities, awareness campaigns and hygiene promotion, helping residents adopt safer practices during the emergency period.
Yet Abba believes emergency support must evolve into longer-term resilience.
He identified healthcare, potable water, sanitation, agriculture, livelihoods and emergency response as areas requiring sustained investment and attention over time consistently.
Mashamari’s vulnerability is compounded by displacement, with people arriving from several local government areas and placing additional pressure on already limited infrastructure, healthcare services and social amenities available locally and facilities.
The community’s experience demonstrates why cholera prevention cannot depend solely on emergency treatment after transmission begins; it must address the environmental conditions that allow contaminated water and poor sanitation to persist.
In Dalori Gari, Konduga Local Government Area, resident Bukar Lawan knows the stakes personally. His daughter survived cholera after receiving timely treatment through referral support provided during intervention activities there safely.
Lawan described the assistance as lifesaving for vulnerable households, but pointed to inadequate water supply and poor sanitation facilities as continuing threats that could trigger another outbreak soon in the future.
His call for additional water, sanitation and hygiene projects, including toilet construction, reflects a broader demand from communities: prevention must reach homes, schools, markets and public spaces before disease spreads widely.
Dr Jide Idris, the Director-General, Nigeria Centre for Disease Control and Prevention (NCDC), said Nigeria had recorded more than 65,000 suspected cholera cases across 35 states and about 195 Local Government Areas nationwide.
Although cases had declined substantially from their earlier peak, Idris warned that transmission remained ongoing, particularly as the rainy season and flooding could contaminate water sources and overwhelm sanitation systems.
The warning is especially significant for communities already struggling with damaged infrastructure. Heavy rains can wash human waste into water sources, turning environmental weaknesses into immediate public health emergencies and communities.
Idris said better outcomes were partly linked to early access to treatment, particularly where services had been brought closer to affected communities, demonstrating the importance of decentralised emergency care when needed.
But the NCDC chief emphasised that treatment alone could not end cholera.
According to him, the disease will continue returning unless authorities confront unsafe water, poor sanitation, open defecation and inadequate hygiene infrastructure across communities.
“Open defecation, damaged water systems and poor sanitation in schools, markets and public institutions continue to expose communities to cholera risks.
“We need sustained investments in water, sanitation, hygiene, environmental health and community awareness to prevent repeated outbreaks,” he said.
Borno’s experience illustrates that principle.
Idris said response teams investigated transmission sources and assessed water supply points to identify gaps in water quality, sanitation and chlorination across affected locations in Borno.
The state has also benefited from treatment, oral cholera vaccination, water chlorination, rehabilitation of water sources and hygiene promotion, measures that combine immediate protection with efforts to reduce future transmission.
In Biu Local Government Area, Primary Health Care Director Alhaji Usman Audu reported that 621 patients were admitted between May and July 21, with 534 treated and discharged successfully at present.
Audu said 13 patients died while 74 remained admitted, with treatment provided through General Hospital Biu and 16 primary healthcare centres serving communities across the local government area and surrounding communities.
He attributed the slowing of cases to proactive measures by the Borno Government, Ministry of Health and Biu Local Government Council, including supplies such as chlorine and oral rehydration solution locally.
The response also included soap, hand sanitisers, knapsack sprayers and medicines, showing how relatively basic supplies can become critical tools when communities face a rapidly spreading waterborne disease during the response.
Audu urged residents to report suspected outbreaks promptly, emphasising that treatment was free.
Such accessibility can remove financial barriers that otherwise delay care and increase the risk of preventable deaths unnecessarily.
Yet Borno’s wider outbreak shows the limits of isolated interventions.
Médecins Sans Frontières (MSF) warned that the disease was overwhelming health facilities in spite of ongoing response efforts across affected communities and settlements nationwide.
MSF said inadequate access to clean water, sanitation and healthcare services was driving transmission, while the Borno Ministry of Health had recorded more than 35,500 suspected cases and 198 deaths.
Among those affected was 13-year-old Muhammad Usman, whose severe symptoms included vomiting, diarrhoea and stomach pain before he lost consciousness, illustrating how quickly cholera can become life-threatening among children.
“He started vomiting, had diarrhoea and complained of stomach pain. Later, he lost consciousness.
“We realised it could be cholera,” said Hadiza Ali, Usman’s mother during the ordeal at the time.
MSF currently supports two Cholera Treatment Centres, five Cholera Treatment Units and 17 Oral Rehydration Points, bringing care closer to communities while helping reduce pressure on hospitals in affected communities nearby.
Bienfait Tombola, MSF Project Medical Coordinator, said the organisation had treated more than 24,000 suspected cholera patients by July 12, but warned that transmission was spreading faster than containment efforts could keep pace in affected areas.
“We have significantly expanded our response over the past two months, but the transmission is still spreading faster than efforts to contain it,” he said.
Tombola said the continuing spread was driven by inadequate clean water, sanitation and healthcare access, reinforcing a lesson repeatedly emerging from affected communities: cholera thrives where basic services remain fragile.
MSF has intensified community awareness, preventive measures, healthcare worker training and access to safe water at critical facilities, while also warning that transmission had extended beyond Borno into Plateau across communities.
Plateau Commissioner for Health, Dr Nicholas Ba’amlong, provided an official update.
He said the state recorded 441 suspected cholera cases, 26 confirmed infections and 14 deaths after the outbreak began in June.
Ba’amlong said cases occurred in Mangu, Jos North, Jos South and Barkin Ladi, while the ministry strengthened emergency response and worked with local councils, NCDC and development partners across Plateau communities.
The state increased community engagement through traditional rulers, religious leaders and community influencers, alongside radio, television and outreach campaigns designed to encourage prompt treatment and discourage self-medication widely across the state.
Residents were advised to drink boiled, chlorinated or treated water, wash hands with soap, maintain environmental sanitation, avoid open defecation and practise safe food handling to reduce transmission every single day.
Such measures may appear simple, but UNICEF WASH Specialist Ms Nambam Michael said their consistent application was central to protecting children from cholera, diarrhoea and other preventable diseases across the state.
During a UNICEF-supported three-day programme in Bauchi, WASH officers from all 20 local government areas received technical support and practical field exposure to strengthen preparedness and response before the rainy season.
Michael said unsafe drinking water, poor sanitation and inadequate hygiene continued to fuel cholera, placing millions of children at risk and making sustained WASH investment a child-survival priority across the state.
“It is not enough to have water for drinking; the water must be clean and safe, especially for children,” she said.
Water supplied to households can become contaminated through damaged distribution systems or polluted environments when safety measures fail, making regular testing and treatment essential for household consumption for household use.
Michael also identified open defecation as a major driver of cholera transmission, warning that human excreta can contain millions of bacteria and viruses capable of causing dangerous diarrhoeal diseases in communities.
She urged households to use improved toilets and completely eliminate open defecation, while promoting regular handwashing with soap at critical times to reduce infection risks substantially and prevent further infections.
According to Michael, proper handwashing with soap can reduce diarrhoeal disease risks by more than 50 per cent, underscoring how behaviour change can complement infrastructure investment and
Observers say the evidence from Borno, Bauchi and Plateau is clear: early treatment saves lives, but prevention begins long before patients reach treatment centres, through clean water, functioning toilets and sustained community awareness. (NAN
