When Sharadindu Ghosh was young, he was taught not to speak about his father's leprosy. He, like many others, grew up in the lanes of Jamuria Leprosy Colony, in West Bengal, facing stigma and discrimination. Today, years after his father's passing and an endless struggle through poverty, Ghosh is an electrical supervisor and a mentor to local children. “Among the uneducated population in India, people believe that this disease is given by God,” said Mervyn Basil, communications specialist at NGO Until No Leprosy Remains-India (NLR-India).

Leprosy was eliminated as a public health problem in India as per the World Health Organization's criteria of less than 1 case per 10,000 population, at the national level, in 2005. However now, experts say, it is quietly resurfacing, particularly in climate stressed States including West Bengal and Bihar. Floods, displacement and overcrowding have become frequent, leading to these States seeing the disease re-emerge in pockets.

India reported total 1,03,819 new leprosy cases for the year 2022-23 out of which grade 2 disability (G2D) cases were 2,363 (2.28%), amounting to 25% of the new G2D cases of the world, as per a statement given in the Lok Sabha in February 2024.
