• 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 100 million people worldwide. We commissioned independent polls in 2017 and 2018 which suggest that 20 million more people now know what encephalitis is.
