Leprosy symptoms

What is Leprosy? Leprosy is a chronic, progressive bacterial infection caused by the bacterium Mycobacterium leprae. It primarily affects the nerves of the extremities, the skin, the lining of the nose, and the upper respiratory tract. Leprosy is also known as Hansen’s disease. Hansen’s disease produces skin ulcers, nerve damage, and muscle weakness. If it isn’t treated, it can cause severe disfigurement and significant disability. Hansen’s disease is one of the oldest diseases in recorded history. The first known written reference to Hansen’s disease is from around Hansen’s disease is common in many countries, especially those with tropical or subtropical climates. It’s not very common in the United States. The The Mycobacterium leprae causes Hansen’s disease. It’s thought that Hansen’s disease spreads through contact with the mucosal secretions of a person with the infection. This usually occurs when a person with Hansen’s disease sneezes or coughs. The disease isn’t highly contagious. However, close, repeated contact with an untreated person for a longer period of time can lead to contracting Hansen’s disease. The bacterium responsible for Hansen’s disease multiplies very slowly. The disease has an average incubation period (the time between infection and the appearance of the first symptoms) of Symptoms may not appear for as long as 20 years. According to the There are three systems for classifying Hansen’s disease. 1. Tuberculoid Hansen’s disease vs. lepromatous Hanse...

Leprosy, also known as Hansen’s disease, is a chronic infectious disease caused by Mycobacterium leprae. The disease affects the skin, the peripheral nerves, mucosal surfaces of the upper respiratory tract and the eyes. Leprosy is known to occur at all ages ranging from early childhood to old age. Leprosy is curable and treatment during early stages can prevent disability. Leprosy is transmitted via droplets, from the nose and mouth, during close and frequent contact with untreated cases. Symptoms may occur within one year but can also take as long as 20 years or even more to occur. The disease manifests commonly through skin lesion and peripheral nerve involvement. Leprosy is diagnosed by finding at least one of the following cardinal signs: (1) definite loss of sensation in a pale (hypopigmented) or reddish skin patch; (2) thickened or enlarged peripheral nerve, with loss of sensation and/or weakness of the muscles supplied by that nerve; (3) presence of acid-fast bacilli in a slit-skin smear. Skin lesion has usually a different pigmentation than the surrounding normal skin (less pigmented, reddish or copper-coloured) and may have various aspects (flat, raised or nodules). Skin lesion can be single or multiple with a definite loss of sensation. Leprosy is a highly variable disease, affecting different people in different ways, according to their immune response. Those at one end of the spectrum, with a high level of immunity, harbour a low number of bacilli and are refer...

What is leprosy? Leprosy is a chronic infection caused by Mycobacterium leprae ( M. leprae) bacteria. It can affect the skin and the nerves of the hands and feet as well as the eyes and the lining of the nose. In some cases, leprosy can also affect other organs, such as the kidneys and testicles in men. If left untreated, leprosy can cause deformities of the hands and feet, blindness, and kidney failure. Leprosy is also called Hansen’s disease. Symptoms of leprosy Leprosy progresses very slowly. Most people who have leprosy do not develop symptoms for at least a year after being infected by the bacteria. In most cases, it takes 5 to 7 years for symptoms to develop. Leprosy damages the nerves and muscles. It may cause sores, lesions, lumps, and bumps to appear on the skin. There are 2 types of leprosy: tuberculoid leprosy and lepromatous leprosy. Tuberculoid leprosy is the less severe and less contagious form of the disease. Lepromatous leprosy is more severe and generalized. It is also more contagious. This type of leprosy may affect organs such as the kidneys, testicles (in men), eyes, and nose. Depending on the type of leprosy, symptoms may include: • Skin sores or lesions that do not heal after several months (lesions are flat or slightly elevated and light in color or slightly red) • Skin lumps and bumps that can be disfiguring • Numbness of the skin because of damage to the nerves under the skin • Muscle weakness What causes leprosy? Doctors aren’t exactly sure how le...

What Is Leprosy? But leprosy isn’t that contagious. You can catch it only if you come into close and repeated contact with nose and Today, about 208,000 people worldwide are infected with leprosy, according to the World Health Organization, most of them in Africa and Asia. About 100 people are diagnosed with leprosy in the U.S. every year, mostly in the South, California, Hawaii, and some U.S. territories. Leprosy Symptoms Leprosy primarily affects your skin and nerves outside The main symptom of leprosy is disfiguring skin sores, lumps, or bumps that don’t go away after several weeks or months. The skin sores are pale-colored. Nerve damage can lead to: • Loss of feeling in the arms and legs • Muscle weakness It usually takes about 3 to 5 years for symptoms to appear after coming into contact with the bacteria that causes leprosy. Some people do not develop symptoms until 20 years later. The time between contact with the bacteria and the appearance of symptoms is called the incubation period. Leprosy's long incubation period makes it very difficult for doctors to determine when and where a person with leprosy got infected. What Causes Leprosy? Leprosy is caused by a slow-growing type of bacteria called Mycobacterium leprae ( M. leprae). Leprosy is also known as Hansen's disease, after the scientist who discovered M. leprae in 1873. It isn’t clear exactly how leprosy is transmitted. When a person with leprosy M. leprae bacteria that another person breathes in. Close physica...

For centuries, leprosy was considered a highly contagious and dangerous disease that only struck — and deformed — those who were unlucky enough to be cursed. ( tzaraat) not only refers to a skin condition, but also “the state of ritual impurity” and punishment for sins . The real meaning of leprosy was simply lost in translation somewhere along the way. ( Despite the lingering mystery and stigma, the medical community now understands that leprosy, also known as Hansen’s disease, is a chronic and progressive infectious disease caused by a slow-to-grow bacterium called Mycobacterium leprae ( M. leprae). (3) This bacterium invades the skin, eyes, nasal lining, and peripheral nerves (nerves outside the brain and spinal cord). (3) And while leprosy is, in fact, contagious, it’s not nearly as transmissible as was thought in ancient times, which means that isolating those infected is never warranted. (1, Unfortunately, there are usually no immediate leprosy symptoms to clue you in that you’ve become infected by M. leprae. Instead, it can take at least a year to develop symptoms, with most people showing signs of leprosy only five to seven years after contracting the disease. ( In general, leprosy affects the skin (in the form of rashes, lesions, and bumps) and the peripheral nerves. Numbness on skin spots, loss of feeling in the hands and feet, and muscle weakness are all symptoms of peripheral nerve loss. Leprosy symptoms vary depending on how far the disease has progressed.
