World Down Syndrome Day

Down syndrome occurs when an individual has an extra partial (or whole) copy of chromosome 21. It is not yet know why this syndrome occurs, but Down syndrome has always been a part of the human condition. It exists in all regions across the globe and commonly results in variable effects on learning styles, physical characteristics and health.

Adequate access to health care, to early intervention programmes, and to inclusive education, as well as appropriate research, are vital to the growth and development of the individual.

In December 2011, the General Assembly declared 21 March as World Down Syndrome Day (A/RES/66/149). The General Assembly decided, with effect from 2012, to observe World Down Syndrome Day on 21 March each year. In order to raise public awareness of Down syndrome, the General Assembly invites all Member States, relevant organisations of the United Nations system and other international organisations, as well as civil society, including non-governmental organisations and the private sector, to observe World Down Syndrome Day in an appropriate manner.
