About World Meningitis Day
World Meningitis Day is marked on October 5 as a global effort to improve awareness of meningitis, prevention, survivor support and timely access to healthcare.
The Confederation of Meningitis Organisations (CoMO) founded the campaign in 2009; Meningitis Research Foundation coordinates the current international network.
Why World Meningitis Day matters
Meningitis can be caused by different infections, and bacterial meningitis in particular can become a medical emergency.
Awareness activities should highlight official public-health information and respectful survivor advocacy, never use a personal story without permission or offer individualized diagnosis.
History of World Meningitis Day
CoMO initiated World Meningitis Day in 2009, with later international collaboration from Meningitis Research Foundation and public-health bodies.
The date has changed: the World Health Organization records World Meningitis Day on April 24 in 2021, while its 2024 materials and current CoMO campaign use October 5. Earlier editions must not be retroactively described as October 5.
