World Leprosy Day is a celebration of the leprosy community and an opportunity to raise public awareness of leprosy, also known as Hansen's disease.

The 2023 Campaign: Act Now. End Leprosy.

This year, we celebrate World Leprosy Day on 29 January 2023. The theme of World Leprosy Day 2023 is “Act Now. End Leprosy.”

Our campaign, informed by persons affected by leprosy and developed in partnership with ILEP organizations, draws attention to the fact that we have the tools to interrupt transmission and calls for countries to prioritize leprosy elimination.

We will also share videos from many persons affected, who share the challenges they have experienced as a result of their leprosy diagnosis. Suffering from leprosy is needless, and we have much to learn from people with lived experience of this disease.

We invite you to join us in recognizing World Leprosy Day on Twitter and Facebook.

About World Leprosy Day

On the last Sunday of January*, the international community advocates for the rights of people who have experienced Hansen’s disease and joins in the work to combat the medical and social implications of this neglected tropical disease.

World Leprosy Day was established in 1954 by French journalist and activist, Raoul Follereau. Follereau created World Leprosy Day with two goals: to advocate for the equal treatment of persons affected by leprosy and to reeducate the public about leprosy by correcting historical misconceptions surrounding the disease.

*In India, Leprosy Day is always celebrated on 30 January, the anniversary of Mahatma Gandhi’s death.
