World Down Syndrome Day

World Down Syndrome Day History

World Down Syndrome Day (WDSD) seeks to raise awareness about Down Syndrome. Originally instituted by the United Nations General Assembly in 2011, the day aims to promote inclusivity, understanding, acceptance and well-being of people with Down Syndrome. The observance seeks to highlight the inherent rights, contributions and potentials of those affected and to challenge the prejudices or misinformation associated with the genetic condition.

WDSD’s relevance to South Africa is steeped in the global context. The genetic disorder is one of the most common chromosomal abnormalities in the human population, including South Africa. The National Down Syndrome Association of South Africa reports that one in every 500 to 600 births in South Africa are children with Down Syndrome. This makes WDSD a significant event for many South African families. South Africa’s history with Down Syndrome has seen significant steps taken in raising awareness, promoting inclusivity and providing support. The observance day helps to further these causes.

In South Africa, World Down Syndrome Day is commemorated through various activities designed to educate the public and advocate for the rights and well-being of individuals with Down Syndrome. These include awareness campaigns, education programs, public forums, and media engagements. These efforts are undertaken by multiple stakeholders, including families, communities, advocacy groups, government and non-government institutions. These activities also serve to echo the global theme of WDSD. As with the rest of the world, World Down Syndrome Day is observed in South Africa on the 21st of March, a date symbolically representing the triplication of the 21st chromosome, which results in Down Syndrome.
