By SADIQ ABUBAKAR, Maiduguri –
As part of its efforts to control the spread of cholera outbreak in North East Nigeria, the MSF emergency teams have partnered the Federal Ministry of Health in establishing six cholera treatment centres across the region and treating more than 20,000 patients so far.
A statement issued on Monday by Abdulkareem Yakubu, MSF North East, Field Communication Officer said despite this, MSF teams were still admitting more than 100 patients daily at some points in August, underscoring the severity of the outbreak and the determination of patients to get treatment.
MSF however, said that in many areas, security posed an additional challenge. For instance, in Zamfara state, many patients arrive in a serious or critical condition, having delayed seeking treatment for fear of encountering violence or danger on the roads.
“Vulnerable populations in Nigeria were already in a dire situation,” says Dr Simba Tirima, MSF country representative in Nigeria. “Cholera has added to a complex web of medical and humanitarian vulnerabilities, coming on top of heightened insecurity, a chronic state of acute humanitarian and medical needs, and the direct and secondary impacts of COVID-19.”
At the peak of the outbreak in July, the Nigerian Centre for Disease Control reported more than 7,500 new cases per week and many medical facilities were at risk of being overwhelmed.
“We had to admit 80 or 90 patients during a single work shift,” says Anas Al-Hassan, a nurse at MSF’s CTC in Kano, where the outbreak spread quickly throughout the community. “There was no time for rest because of the number of patients. The work at that time was overwhelming.”
“The patients would come devastated, their caregivers worried they might not make it,” says Philip Esenwa, MSF medical activity manager for the Nigeria Emergency Response Unit. “Some were so weak they that they couldn’t speak.”
“We used to have patients who were brought in dead,” says MSF nurse supervisor Mustapha Mahmud, who also works at Kano CTC.
The challenges were immense in cities such as Kano and Bauchi, where many people live in overcrowded conditions, with dilapidated or non-existent sewage systems and no access to clean drinking water. Water sources can easily become contaminated with sewage, especially in the rainy season, causing waterborne diseases such as cholera to spread quickly.
“The areas with high numbers of cholera cases are congested, with no adequate ventilation or proper drainage,” says Mustapha Mahmud. “The sources of water are usually from shallow wells and boreholes; with rainfall, they become contaminated, and that is the water people here drink.”
Many medical facilities in these areas are also poorly equipped and were unable to deal with the surge in patients. Some medical facilities charge for their services, which put treatment out of reach of those who could not afford to pay.
To grapple with these complex challenges, MSF adopted a community-based approach, taking healthcare, hygiene measures and public health information directly to the affected communities. MSF health promotion teams worked with Ministry of Health staff to conduct door-to-door contact tracing to find people with symptoms and help them get medical care quickly, while outreach teams chlorinated wells and disinfected patients’ homes.
Working with community leaders, MSF teams also identified neighbourhoods with high concentrations of cases to set up oral rehydration points, where patients with milder symptoms could receive treatment.
In some states, a one-dose oral vaccine is available to help reduce the spread of the disease. However, global supply is limited and the vaccine is not available in all states.
In the areas where MSF is responding, these and other efforts have made a difference. In Bauchi state, where MSF set up 19 oral rehydration points and a cholera treatment unit, and carried out health promotion and hygiene activities, the mortality rate has been reduced by a factor of ten, from 5% to less than 0.5%, and the number of new patients being admitted for treatment continues to decline.
The trend of declining cases holds true for the country overall, with new cases in recent weeks falling to below 1,000 per week from a peak of 7,500. In many areas, this has brought a sense of palpable relief for communities and medical teams alike.
“Thankfully, there has finally been a significant decline in the number of new cases in most areas,” says Dr Tirima. Elsewhere in the country, however, the outbreak rages on. “Other areas continue to be affected and the response is not over yet,” he warns.
One of those areas is Borno state, where hundreds of thousands of people have been displaced from their homes by clashes between government forces and armed insurgent groups. Years of conflict, displacement and underdevelopment have left the population struggling to access clean water and decent sanitation. In the state capital, Maiduguri, the MSF team continues to treat nearly 200 patients per week for cholera and acute watery diarrhoea.
Four hundred km northeast of the Nigerian capital Abuja, two-year-old Mohammad Sheriff is on the road to recovery from cholera. The child sits with his father in MSF’s cholera treatment centre (CTC) in Bauchi, the capital of one of the states hit hardest by Nigeria’s worst cholera outbreak in a decade.
“He vomited twice and later started having diarrhoea,” says Mohammad’s father, who immediately recognised the symptoms as cholera. “I told his mother that I’d take him to the hospital as we are constantly being informed through the radio that one should immediately go to hospital when vomiting and diarrhoea starts.”
Cholera is simple to treat in most cases, and people with mild to moderate forms of the disease usually recover through treatment with fluids and oral rehydration solution. Severely dehydrated patients may need to be admitted to a CTC and be given fluids intravenously.
Mohammed’s case was serious, but after two days receiving medical care in the CTC, he is now in the recovery ward – the last step before being discharged and returning home. “If we had not come when we did, the situation might be very bad,” his father says.
Cholera is endemic in Nigeria, but the outbreak this year has been especially severe, with more than 90,000 people infected so far. While nearly all of Nigeria’s 36 states have reported cholera cases in 2021, the vast majority have been concentrated in the six northern states of Bauchi, Kano, Jigawa, Zamfara, Sokoto and Katsina. The population of this region is already extremely vulnerable; hundreds of thousands of people have been displaced from their homes by conflict and violence, and most live in conditions with poor sanitation and no safe drinking water.
