The health situation in Borno State in northeast Nigeria is critical. At least 500,000 people who are either displaced or cut off in enclaves outside the State capital of Maiduguri are in urgent need of food, medical care, drinking water and shelter.

“Aid agencies must deploy a massive relief operation to respond to this health disaster,” says Dr Isabelle Defourny, director of operations at Médecins Sans Frontières (MSF).

As the army regains control of the main towns and some villages in Borno State, the extent of the emergency is becoming all too apparent. Hundreds of thousands of people have been cut off from the outside world, some for as long as two years. They are mostly displaced people, living in towns now controlled by the military, and relying entirely on outside aid.

Assessments by United Nations agencies and the Nigerian authorities have shown how very serious the situation is and teams from SEMA (Borno State Emergency Management Agency), Red Cross and UNICEF have distributed food and provided medical and nutritional treatment at several locations.

In June, an MSF team observed extremely high levels of malnutrition and mortality in Bama, Borno State’s second-largest town. Bama is now a ghost town accessible only under army escort. Its inhabitants, estimated at over 10,000, live in a camp. While there are some food distributions and close to 1,500 people – the most vulnerable and sick – have been evacuated by the authorities, mortality rates are significantly higher than the emergency threshold and 15 per cent of children are suffering from severe acute malnutrition.

An MSF team has arrived in Bama to provide support with medical and nutritional treatment. Their objective is to rapidly reduce mortality and malnutrition among the displaced. The most critical cases will be transferred to Maiduguri. Equally urgent is improving access to water as well as hygiene conditions in the camp.

Monguno, a town of 150,000 inhabitants – 65,000 of whom are displaced – has been without medical care since January 2015. MSF plans to re-launch activities at the hospital and treat displaced and local children with severe acute malnutrition.

People are queuing for screening. The displaced population in Bama camp is estimated between 10,000 to 12,000 persons.

“A massive aid effort is vital to provide assistance to people who are cut off or in remote areas”, continues Dr Defourny. “Everything suggests that the situation of people in other towns like Dikwa is just as critical and that they also need food and medical care.” MSF is conducting other exploratory missions when and where it can, as insecurity is a major issue. Bama and Dikwa and areas close to the frontline exposed to attack by Boko Haram can only be reached under army escort.

Meanwhile, the displaced are continuing to seek refuge in Maiduguri. With such an influx of people, the town’s hospitals are overwhelmed and have to turn patients away. Only recently, six children with measles who could not be admitted to hospital were sent back to the displaced persons camp where their families had just arrived. Increasing inpatient capacity in Maiduguri is therefore another of MSF’s priorities.
