What is Leprosy?

·         Leprosy is a chronic infectious disease caused by Mycobacterium leprae (M. leprae).

·         It mainly affects the skin, peripheral nerves, and mucous membranes.

·         It is a disease mainly of human beings, which affects people of all races, all ages, and both sexes.

·         Similar to TB, leprosy bacilli are mainly transmitted through infectious droplets that are spread by an infectious individual through coughing and sneezing.

·         Patients carrying many leprosy bacilli are called multibacillary (MB) patients.

·         They are the main source of infection.

·         People may carry the bacilli but not develop the disease.

·         These people, called healthy carriers, are also probably able to transmit the bacilli to others.

·         Individuals with few bacilli in their body are called paucibacillary (PB).

·         Like healthy carriers, they are not a significant source of infection.
