Meningitis remains a public health problem due to its high mortality and severe sequelae in children. Worldwide approximately 8.5 million new cases of meningitis and 463 000 deaths were reported in 2019. In Africa, during the epidemic season, 24 countries reported a total of 15,324 suspected cases, including 915 deaths in 2019. The weekly incidence rate exceeds 10 suspected cases and more than 25,000 suspected cases are reported each year. In Niger in 2015, following an epidemic, 2102 cases of meningococcal meningitis including 129 deaths were reported. Despite the remarkable progress made over the past 20 years in the fight against meningitis, this disease is still relevant in public health in Niger. Our work is part of this logic by proposing to evaluate the meningitis surveillance system in Niger in 2021 in order to improve it.
