World Encephalitis Day 2. Camera Every year we ask our supporters to wear something red on World Encephalitis Day – 22nd February - and then share their photos on social media accounts and telling their followers and friends about why they are wearing red. Wearing something red for our supporters could mean anything - from a red onesie through to a red hat, red shoes, red umbrella, a red bow tie or even our official World Encephalitis Day t-shirts. If you want to take part on World Encephalitis Day, please make sure to use the hashtag #Red4WED on Twitter and Instagram so we can share it to our official World Encephalitis Day website. We also have official #Red4WED t-shirts available from our shop and resources which can be downloaded for either social media or as posters.
