In line with the Defeating meningitis by 2030: a global road map, the WHO guidelines on meningitis diagnosis, treatment and care Executive Summary provides a summary of the evidence-based recommendations for the clinical management of children and adults with community-acquired meningitis, including acute and long-term care.

The burden of morbidity and mortality from meningitis remains high, particularly in low- and middle-income countries and in settings experiencing large-scale, disruptive epidemics.
