Outbreak detected six days before laboratory confirmation
A cholera outbreak at the Kurmawa Medium Security Custodial Centre in Kano State has been contained after claiming two lives, the Nigerian Correctional Service (NCoS) has disclosed.
The Service confirmed that one of the victims died at the custodial facility, while the second died at the Kano State Infectious Diseases Hospital.
The outbreak was confirmed through laboratory investigation on September 23 by the NCoS medical team in collaboration with Kano State public health authorities.
According to a statement by the Service Public Relations Officer, Chief Superintendent of Corrections JN Osuji, the first indication of the outbreak came on September 17 when an inmate developed vomiting and diarrhoea.
He was admitted to the facility’s medical unit and treated, while emergency medical protocols were activated the following morning as health personnel intensified treatment and surveillance.
The six-day interval between the first reported symptoms and laboratory confirmation highlights the importance of early detection in a confined environment, where infectious diseases can spread quickly when people live in close proximity.
NCoS steps up surveillance
The Controller-General of Corrections, Sylvester Ndidi Nwakuche, was briefed about the situation and directed that measures to protect inmates and personnel be sustained.
NCoS said the interventions have brought the outbreak under control and that no additional mortality has been recorded since the diagnosis.
The Controller-General also ordered senior medical personnel from the Service’s National Headquarters to travel to the facility and monitor the situation.
Additional preventive measures are being implemented in conjunction with the Kano State Government, while disease surveillance, early identification and prompt treatment have been strengthened.
Nwakuche expressed condolences over the deaths and reaffirmed the Service’s commitment to protecting the health and welfare of people in custody under the Nigerian Correctional Service Act, 2019.
Conflicting death figures emerge
The official toll from NCoS differs from an earlier account by Amnesty International.
The rights organisation had raised concern over the situation at the Kurmawa facility and reported that at least six inmates had died from a suspected cholera outbreak. Amnesty also warned that the number could increase and called attention to conditions including overcrowding and inadequate healthcare.
NCoS, however, has confirmed two deaths linked to the outbreak.
The difference is important because the two figures describe different stages and sources of reporting. The NCoS figure is the official toll released after laboratory confirmation, while Amnesty’s earlier figure was based on information available to the organisation before the Service’s confirmation.
No additional death figure has been independently established in the information released by the authorities.

Why cholera is a concern in custodial facilities
Cholera is an acute diarrhoeal infection that can cause severe dehydration and death within hours if treatment is delayed. The World Health Organisation identifies unsafe water, inadequate sanitation and poor hygiene as major factors behind transmission.
The risk can become more difficult to manage in overcrowded settings. WHO specifically identifies prisons and other densely populated environments as places where inadequate water, sanitation and hygiene facilities can facilitate cholera transmission.
That makes the condition of custodial facilities an important part of outbreak control. Medical treatment can save patients who become severely dehydrated, but prevention also depends on safe drinking water, proper sanitation, food hygiene, environmental cleanliness and effective disease surveillance.
Kano already facing congestion concerns
The latest incident comes days after Kano authorities began another effort to address congestion and welfare concerns in custodial facilities.
On September 15, the Kano State Council for Prerogative of Mercy, working with NCoS, began visits to selected custodial centres to examine inmates’ welfare and challenges affecting rehabilitation and reintegration. The initiative was described by the Kano NCoS command as part of efforts to reduce congestion and improve conditions in the facilities.
NCoS had also reported in April that its Kano Command recorded 151 non-custodial sentences in the first quarter of 2026, reflecting the use of alternatives to imprisonment as part of efforts to ease pressure on custodial centres.
The cholera episode therefore places renewed attention on the connection between custodial population management and public health. Even after an outbreak is brought under control, sustained monitoring is necessary to detect fresh cases before they develop into another cluster.
NCoS said healthcare services are available through qualified medical personnel across custodial facilities and that collaboration with public health authorities will continue.
The Service also advised the public to rely on verified information from official channels as monitoring of the Kurmawa situation continues.
While authorities have declared the outbreak contained, the two confirmed deaths, the earlier conflicting reports and existing concerns about custodial conditions underline the need for transparent surveillance, rapid medical intervention and strong water, sanitation and hygiene measures at the facility.
