Welcome everyone to World Leprosy Day, occurring on January 28, a crucial day that shines a spotlight on an age-old disease that many perhaps, mistakenly, consider a thing of the past. Begun by French humanitarian Raoul Follereau in 1954, World Leprosy Day is a springboard for global initiatives to combat this misunderstood disease, which is completely curable but suffers from centuries of misinformation and stigma. As we unite in positive action, let's unmask the truth about leprosy together, challenge misconceptions and catalyze the crucial work towards a future where no one suffers from this curable condition. Join us to lend your voice and spread awareness about leprosy, because together, we can make a difference!

TIMELINE

World Leprosy Day Timeline

Cause of Leprosy Discovered

Norwegian physician Gerhard Hansen discovered Mycobacterium leprae, the bacterium that causes leprosy, making it the first bacterium to be identified as causing disease in humans.

Dapsone Treatment

The antibiotic Dapsone was introduced in the 1940s as the first effective treatment for leprosy, although it later proved to be insufficient as a standalone therapy.

World Leprosy Day Established

French humanitarian Raoul Follereau established World Leprosy Day to raise awareness about leprosy and its victims, and to advocate for research and funding.

WHO Multidrug Therapy

The World Health Organization introduced a multidrug therapy regime for leprosy, dramatically improving cure rates and marking a significant milestone in the fight against the disease.

Leprosy Elimination Target

The WHO announced that leprosy had been eliminated as a public health problem worldwide. The target was defined as reducing the global prevalence of the disease to less than one case per 10,000 population.

Continued Awareness Efforts

On World Leprosy Day 2022, organizations and advocates worldwide continue to fight stigma, raise awareness, and support ongoing research for a leprosy-free future.
