- *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.
-
†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.
-
‡ 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.
