Pneumococcal meningitis remains a public health problem in Burkina Faso. The aim of our study was
to determine the prevalence of pneumococcal meningitis in the infectious diseases department of
CHU Yalgado Ouédraogo.
Patients and Methods: It was about a retrospective and descriptive study of the records of patients
hospitalized for pneumococcal meningitis in the department of infectious diseases at CHU YO Burkina
Faso during the period going from January 1
st 2000 to December 31st 2019.
Results: In 20 years, 393 cases were collected, representing a proportional morbidity of 7%. The sex
ratio M / F was 1.6 and the average age was 26,8 years [19 days -90 years]. The majority (91%) of
patients were from suburban areas of the city of Ouagadougou. Housewives, farmers and students
were the most affected with 23%, 10% and 9%. The annual peaks of meningitis cases were recorded
between January and April, which corresponds to the dry season. The evolution was lethal in 30.31%.
The frequency of pneumococcal meningitis at CHU-YO remains relatively high with a heavy lethality.
Hence the need to promote pneumococcal vaccination and strengthen the technical platform for an
appropriate treatment of cases
