ABSTRACT: Introduction: Meningitis caused by Neisseria meningitidis constitutes a burden for the countries in the meningitis belt of sub-Saharan in general and particularly for Burkina Faso. In 2019 the Diapaga health district experienced a meningitis epidemic due to N. meningitidis serogroup C. Methods: This is a cross-sectional study with a descriptive aim in the health district of Diapaga where all cases of meningitis were included in this work. Rapid diagnostic tests (RDTs), culture as well as real-time PCR were used for the biological analysis of cerebral spinal fluid (CSF) samples. Results: Of 155 CSF samples analysed, 42% (65/155) were tested positve. Of them, N. meningitidis C accounted for 83% of all positive cases. Likewise, all thirteen (13) NmC strains were susceptible to oxacillin, ceftriaxone, penicillin and chloramphenicol. All strains of NmC belonged to the sequence type (ST) 10 217 and to the clonal complex (CC) 10 217. These CCs belonged to the same variant PorA type: P1.21-15.16; FetA type: F1-7; PorB type: 3-463. Conclusion: Burkina Faso had known an epidemic of meningitis caused by NmC in 2019 in the health district of Diapaga. This outbreak was contained in time due to the performance of the epidemiological surveillance system which made it possible to investigate on time and introduce the vaccine against the pathogen NmC.
