About World Encephalitis Day

World Encephalitis Day (WED) is a global awareness day where individuals and families affected by encephalitis come together to shine a light on the condition. Founded by The Encephalitis Society in 2014, it is held on February 22 each year and has reached millions of people over the years through media features, events and social media.

WED has a special meaning to all those affected by encephalitis. It is a day to become vocal and raise awareness, to share your journey with others. WEDA has chosen this important day to host their yearly conference, to support and strengthen those affected by encephalitis through education and connection.
