A total of 156 landmarks lit up red in support of World Encephalitis Day on 22nd February, 2021.

World Encephalitis Day 2021 on 22nd February, 2021, saw us reach over 50 million people through our media campaign as well as turn social media into a sea of red as our supporters joined us in going #Red4WED.

The centrepiece of our annual campaign was lighting up 156 landmarks in 23 countries around the world, including Niagara Falls, the Cameroon Reunification Monument, Alexandra Palace in London, the Sails of Light in Vancouver and more than 50 hospitals in India.

The response in 2021 sincerely blew us away and made all our hard work worthwhile.

THANK YOU to each and everyone of you who has come out to raise awareness of encephalitis and gone #Red4WED - it means the world to all of us and shows what can be achieved when we all come together.

Oxford Autoimmune Neurology Group

Dr Christopher Uy is a Clinical Research Fellow with the Oxford Autoimmune Neurology Group. He is also a talented videographer and together with his research colleagues, including Professor Sarosh Irani, put together this film which explores what happens when a patient is admitted to John Radcliffe Hospital, Oxford, with autoimmune encephalitis.

Fun and interesting - it gives you an idea of just how many experts care for a patient and also tackles bigger questions leading to insights and discoveries about the causes of these diseases.


Speaking of Christopher - he is also a talented acrobat!
