Many people mistakenly believe that leprosy has been eradicated. It has an almost historical aura and even the name suggests an ailment from an earlier era. But for sufferers, the disease is a reality they must live with every day.

Leprosy, also known as Hansen's disease, has afflicted humanity for more than 4,000 years. It is caused by bacteria, Mycobacterium leprae, that damage the skin, nerves, limbs and eyes. The disease can result in severe scarring, especially on the face and limbs.

The symptoms can take months or even years to appear. The limbs of the afflicted person lose all sensitivity, resulting in easy damage to extremities such as fingers and toes. Sometimes, tissue loss results in shortened fingers and legs.
