Population and incidence in 26 surveyed districts years at the district level and at the health centre level. If not indicated otherwise, the health centre level columns show median (range).

Peak WIR, highest weekly incidence rate (per 100,000) observed during a given year

HC, health centers

na, not applicable

* A localised epidemic (LE) was defined at the health centre level as 75 suspected meningitis cases reported per 100,000 inhabitants during at least two consecutive weeks, with a minimum of five cases within at least one week.

† In all district years, the annual incidences between health centres with and without localised epidemic differed significantly (P < 0.001, Poisson model).
