Which among the following is  a bacterial disease ?

Leprosy

The correct answer is Option (2) – Leprosy

Leprosy is a bacterial disease.

Leprosy, also known as Hansen's disease, is a chronic infectious disease caused by the bacterium Mycobacterium leprae. This bacterium primarily affects the skin, peripheral nerves, mucosal surfaces of the upper respiratory tract, and the eyes. Leprosy is transmitted through prolonged close contact with untreated individuals who have the active, infectious form of the disease. It mainly affects the skin and peripheral nerves, leading to characteristic skin lesions, nerve damage, and deformities if left untreated. Leprosy has been known since ancient times and continues to be a significant public health concern in some regions of the world, particularly in tropical and subtropical areas with poor healthcare infrastructure. Treatment for leprosy involves multidrug therapy, which can effectively cure the disease and prevent further transmission when administered appropriately.
