Leprosy is caused by a slow-growing bacillus, Mycobacterium leprae. It is transmitted via droplets from the nose and mouth of untreated patients with severe disease. However, it is important to note that Leprosy is not a highly infectious disease. If left untreated, the disease can cause nerve damage, leading to muscle weakness and atrophy, and permanent disabilities.
Timely diagnosis and treatment of leprosy is the most effective way of preventing disabilities and is also effective to stop transmission.
Leprosy can be easily treated and completely cured with a 6–12-month course of multidrug therapy (MDT). MDT is available free of cost in all health facilities including those in the periphery.
