Abstract
In sub-Saharan Africa, the control of meningococcal meningitis epidemics relies on early epidemic detection and mass vaccination. However, experience shows that interventions are often initiated too late to have a significant impact on the epidemic. A new recommendation drafted by participants of a consensus meeting proposes an alert threshold and an epidemic threshold based on the weekly number or incidence of meningitis cases, according to the population size and the epidemic risk, resulting in indicators with high sensitivity and specificity for the detection of an emerging epidemic. Meningitis outbreak investigations must include an assessment of the quality of epidemiologic surveillance. The new recommendation is published in English and French in the Weekly Epidemiologic Record [12]. The success of this consensus meeting shows the value of integrating results from surveillance, field experience and operational research for designing new health strategies.
