• Encephalitis is inflammation of the brain – a devastating neurological condition.
  • Anyone can be affected by encephalitis irrespective of age, sex or ethnicity.
  • 500,000 children and adults are affected by encephalitis every year, that is one person every minute.
  • Symptoms of encephalitis vary but can include flu-like illness or headache, drowsiness, uncharacteristic behaviour, inability to speak or control movement and seizures.
  • Death rates are high.
  • Survivors can be left with an acquired brain injury resulting in epilepsy, fatigue, cognitive difficulties, problems with memory and personality.
  • There is low awareness of the condition – 78% of the general public worldwide do not know what encephalitis is.*
  • World Encephalitis Day on 22 February is a day which celebrates and honours the millions of lives affected by encephalitis, which is brain inflammation.
  • Encephalitis Society leads World Encephalitis Day every year and asks people to show their support by wearing red as part of their #Red4Wed campaign.
  • Since its launch in 2014, World Encephalitis Day has reached over 187 million people worldwide through social and traditional media.
