What is leprosy and what are the leprosy eradication programs world wide?
7 answers
Leprosy, also known as Hansen's disease, is a chronic infectious disease caused by the bacterium *Mycobacterium leprae*. It primarily affects the skin, peripheral nerves, mucosa of the upper respiratory tract, and eyes, leading to significant disabilities if left untreated. The disease is characterized by a long incubation period, with symptoms that can take years to appear, making early diagnosis and treatment crucial to prevent long-term disabilities and transmission. Despite being one of the oldest diseases known to humanity, leprosy continues to infect over 200,000 people annually, with significant numbers in under-developed countries. Worldwide, several leprosy eradication programs have been implemented to combat this disease. The World Health Organization (WHO) launched a global strategy in 1982, introducing multidrug therapy (MDT) consisting of dapsone, rifampin, and clofazimine, which significantly reduced the global prevalence of leprosy. Following this, the WHO coordinated efforts from 1990 to 2000 aimed at eliminating leprosy as a public health problem through the widespread use of MDT. The National Leprosy Eradication Programme (NLEP) in India, initiated in 1955, is another example, which adopted MDT in the 1980s with the goal of eradicating leprosy. More recent strategies include the WHO's Global Leprosy Strategy 2016-2020, aiming for a leprosy-free world through active case finding, surveillance, and managing complications and disabilities associated with the disease. The new Global Leprosy (Hansen’s disease) Strategy 2021-2030, 'Towards Zero Leprosy', sets ambitious targets for reducing the disease burden, including a significant reduction in new cases and disabilities, and eliminating stigma and discrimination. Despite these efforts, challenges remain, including drug resistance, the need for new diagnostic tools, vaccines, and the persistent stigma and discrimination faced by those affected. Achieving the goal of zero leprosy requires continued global commitment, innovative strategies, and addressing the social and economic factors that contribute to the disease's persistence.
