The etiological agent of Hansen’s disease is bacteria called Mycobacterium leprae. The mode of transmission is not yet totally known but it is believed that respiratory secretions and saliva drops can spread the disease. Hansen’s disease is a chronic disease (slow progression) that generally attacks the skin and the peripheral nerves although other areas of the body can be affected. In the skin nodules, reddish spots, thickening of the dermis and lack of sensitivity appear; the mucosae, especially the nasal mucosa, may be injured and also the viscera may be affected. The main form of prevention is information, since there is available treatment; infected people should, as soon as possible, look for health services for evaluation and treatment of the disease. In the past Hansen’s disease was called leprosy.
