Area of Science:
- Epidemiology
- Infectious Diseases
- Public Health
Background:
- Niger is situated in the meningitis belt, experiencing recurring epidemics.
- Meningitis outbreaks in the region exhibit significant annual variability.
Purpose of the Study:
- To analyze meningitis trends in Niger from 2008 to 2015.
- To identify the microbial agents responsible for meningitis epidemics in Niger.
Main Methods:
- A descriptive study utilizing secondary analysis of meningitis data.
- Inclusion of all suspected and confirmed meningitis cases reported in Niger between 2008 and 2015.
- Exhaustive sampling of the study population.
Main Results:
- 6,167 confirmed meningitis cases were identified.
- Neisseria meningitidis accounted for 89.3% of cases, followed by Streptococcus pneumoniae (9.6%) and Haemophilus influenzae (1.1%).
- Among Neisseria meningitidis cases, serogroup A was most prevalent (54.2%), with notable proportions of serogroup W (24.2%) and serogroup C (21.1%).
Conclusions:
