Leprosy aka Hansen’s disease after the Norwegian scientist Gerhard Henrik Armauer Hansen, who in 1873 discovered the slow-growing bacterium now known as Mycobacterium Leprae.
Just don't believe old wives' tales. You cannot get leprosy through casual contact, a quite prolonged close contact is needed to catch it. It's believed that the primary mode of transmission is via droplets. Moreover, most of us, nearly 95% of adults has some natural immunity against it. The wonder of evolution.
Also the BCG vaccination could offer some protection because the bacteria that causes Leprosy is closely related to the one that causes TB.
More than half the World's cases are in India, then also in Indonesia, Brazil etc. Then WHO reports countries over 1000 cases annually as Bangladesh, Democratic Republic of the Congo, Ethiopia, Madagascar, Mozambique, Myanmar, Nepal, Nigeria, Philippines, Somalia, South Sudan, Sri Lanka and the United Republic of Tanzania. Leprosy is present in over 120 countries in the world.
Even though we eliminated Leprosy in 1995, sadly we are back in the list. There's an Anti-Leprosy Campaign in action and they say that the Covid time and the fuel shortage had a negative impact on the campaign and these factors caused the cases to go undetected and ramp up.
More than 1,300 new cases were reported in 2022, with 10.6% of the patients being children. The number of cases for the year 2021 was 1,026 and in 2020, 1,213. The number of cases in 2015 was nearly 2,000.
They also say that from 2020 to 2022 they have missed around 3,272 cases.
Treatment is easy using Multi Drug Therapy (MDT) - a combination of drugs are used instead of a monotherapy (one drug) as this could result in developing drug resistance to that particular drug. Seeking proper medical advice during the early stages is the key.
