Meningitis is a serious and potentially fatal infection that causes inflammation of the linings of the brain. It can be caused by either bacterial or viral infections and transmission is thought to occur due to respiratory droplets or via close physical contact.

Symptoms can appear suddenly and include headaches, muscle and joint pain, neck pain or stiffness, fever, photophobia (sensitivity to bright light), sleepiness, confusion, seizures and loss of consciousness. Bacterial meningitis is associated with a characteristic purple (purpuric) rash.
Meningitis occurs worldwide, but particularly in the meningitis belt of sub-Saharan Africa.

The vaccine (ACWY) protects against 4 subtypes of meningitis and its effect lasts for up to 3 years.

All travelers who are vaccinated against Meningitis ACWY will also receive a certificate of vaccination. Hajj and Umrah pilgrims are required to show certification of vaccination on arrival in Saudi Arabia.
