Cholera outbreak kills 74 in Nigeria's Borno state as cases surpass 7,800

A cholera outbreak in Nigeria's northeastern Borno state has killed at least 74 people and infected more than 7,800 since early May, overwhelming health facilities in a region already weakened by years of conflict and displacement, according to Médecins Sans Frontières.

The medical aid group said 7,850 suspected cases had been recorded across 14 local government areas as of June 7, citing figures from the state ministry of health, with infections climbing sharply each day.

The outbreak is placing severe strain on a fragile healthcare system at the center of a 17-year Islamist insurgency that has driven mass displacement and left much of the region without adequate water and sanitation infrastructure — conditions that raise the risk of wider spread if containment efforts falter.

MSF, working alongside the state ministry of health, has established a cholera treatment center in the state capital Maiduguri to support the emergency response.

"Every day, we see more people arriving with severe watery diarrhea and dehydration, many of whom have traveled long distances to reach care," said Bienfait Tombola, MSF's project medical coordinator for the surge response in Maiduguri.

The group said it had treated 7,439 patients so far, averaging roughly 230 admissions a day. More than 500 cases were recorded on June 5 alone — the highest single-day total since the response began.
