The general objective is to define and characterize localized epidemics that occurred in the last 7 years in 13 districts in Burkina Faso and to describe their risk factors.

The study (called “Dynamique et facteurs de risque de la survenue de foyers épidémiques de méningite au Burkina Faso” in French) aims to improve meningococcal meningitis outbreak detection and to describe the impact of vaccination with group A meningococcal conjugate vaccine.
