World Encephalitis Day

World Encephalitis Day 2024 on Thursday, the 22nd of February, is the global awareness day for people who have been directly or indirectly affected by encephalitis.

Since its launch, it has reached millions of people through media features, events and social media.

It is our hope that World Encephalitis Day will play a leading role in our mission to increase global awareness of encephalitis and therefore saving lives and building better futures.

What is encephalitis?

Here are five facts about encephalitis:

1. Encephalitis is inflammation of the brain
2. It is caused by an infection or through the immune system attacking the brain
3. It can have a high death rate and survivors might be left with an acquired brain injury and life-changing consequences
4. Early diagnosis and treatment can save lives and improve outcomes
5. In some cases, encephalitis can impact mental health, causing difficult to deal with emotions and behaviours, and can lead to thoughts of self-harm and even suicide
