Table 3 Streptococcus pneumoniae (Sp) meningitis incidence rates (per 100,000 per year) by age group and country [4, 5, 79]; Neisseria meningitidis meningitis incidences were available from Burkina Faso, Senegal, and Niger and summary means are presented for comparison.

  1. *Not all studies reported age groups at the detail shown in column 1. The incidences in Ghana for persons age 5 to 19, 15 to 29, and 30 to 59 years and in Niger for persons 40+ years were 25, 20, 18, and 7.9 per 100,000 persons per year, respectively.
  2. Weighted mean based on population under surveillance. Where data were not available from a study site for a specific age group, the next oldest age group was used in the calculation of the weighted mean.
  3. Nm = Neisseria meningitidis. For comparison, data on Nm are presented for the same surveillance periods and sites except for Ghana, which did not report these data.
