On December 18, 2007, the United Nations General Assembly adopted resolution 62/139, tabled by the State of Qatar, which declares April 2 as World Autism Awareness Day (WAAD) in perpetuity. Her Highness Sheikha Mozah Bint Nasser Al-Missned, Consort of His Highness Sheikh Hamad Bin Khalifa Al-Thani, the Emir of the State of Qatar, supported the campaign for a World Autism Awareness Day through the current 62nd UN General Assembly Session, garnering consensus support from all United Nations Member States.

The United Nations Secretary-General Ban Ki-moon welcomed the UN World Autism Awareness Day last year. Mr.Ban ki-moon said: 'As we advance the universal human rights of children with disabilities, let us focus on building enabling environments for them to prosper as future members of their communities, citizens of their countries and as fully-fledged members of the global community. Let us pay tribute to the courage of children with autism and their families, as they strive every day to confront the disability with a powerful combination of determination, creativity and hope. Let us empower them and respond to their needs today, so as to make our societies more accessible, enabling and empowering for all our children tomorrow. 

This UN resolution is one of only three official disease-specific United Nations Days and will bring the world's attention to autism, a pervasive disorder that affects tens of millions. The World Autism Awareness Day resolution encourages all Member States to take measures to raise awareness about autism throughout society and to encourage early diagnosis and early intervention. It further expresses deep concern at the prevalence and high rate of autism in children in all regions of the world and the consequent developmental challenges.
