About World Conjoined Twins Day

World Conjoined Twins Day is observed on 24 November. The United Nations General Assembly created the Day to raise awareness of conjoined twins and to promote their health, well-being, human rights and social inclusion.

The observance concerns a rare congenital condition and should be handled with respectful, person-centred language. Medical outcomes vary widely, so general awareness material should not be treated as individual clinical guidance.

Why World Conjoined Twins Day matters

Conjoined twins develop when a single early embryo does not fully separate. Their anatomy, shared organs and medical needs differ from case to case, which means treatment decisions require highly specialized multidisciplinary assessment.

The UN resolution places the observance within a broader health and inclusion framework: improving awareness, strengthening cooperation, supporting families and reducing stigma rather than treating affected people as medical curiosities.

History of World Conjoined Twins Day

Draft resolution A/78/L.72 was sponsored by Bahrain, Comoros, Djibouti, Kuwait, Morocco, Oman, Qatar, Saudi Arabia, Singapore, Turkmenistan, Uganda and Yemen, with Saudi Arabia introducing the text in the General Assembly.

On 1 July 2024, the General Assembly adopted the draft without a vote as A/RES/78/313 and proclaimed 24 November as World Conjoined Twins Day.

The resolution explicitly states that the Day is to be observed each year beginning in 2024. WHO marked the 24 November 2024 observance during the first-ever International Conference on Conjoined Twins in Riyadh.
