March 21 is World Down Syndrome Day

What is World Down Syndrome Day? World Down Syndrome Day (WDSD), 21 March, is a global awareness day which has been officially observed by the United Nations since 2012. The date for WDSD being the 21st day of the 3rd month, was selected to signify the uniqueness of the triplication (trisomy) of the 21st chromosome which causes Down syndrome.

Join us to promote full inclusion - On this day, people with Down syndrome and those who live and work with them throughout the world organize and participate in activities and events to raise public awareness and create a single global voice advocating for the rights, inclusion and well being of people with Down syndrome. Here are some ways you can take action.

What is Down syndrome? Down syndrome (or Trisomy 21) is a naturally occurring chromosomal arrangement that has always been a part of the human condition, being universally present across racial, gender or socioeconomic lines in approximately 1 in 800 live births, although there is considerable variation worldwide. Down syndrome usually causes varying degrees of intellectual and physical disability and associated medical issues.
