Also known as Hansen's disease, leprosy is an infectious disease that has progresses slowly, and mostly affects the cooler parts of the body. According to experts, the time taken by this disease to develop may range from a mere six months to 40 years. The areas of the body such as the eyes, earlobes, hands, testicles and nose are the ones which show the first signs of this disease. If left untreated, the disease may cause permanent damage to the skin, nerves, as well as the eyes and limbs.

Causes of leprosy

Mycobacterium leprae and M. lepromatosis are the organisms responsible for causing this disease. The first bacterium is aerobic and rod-shaped organism that is known to thrive in certain human and animal cells. In case of humans, cells that cover and protect the nerve axons are known to be the targets of these bacteria. The latter one, however, has been identified recently, and is being characterised and studied. These bacteria show an optimum growth at temperatures of 80.9-86 °F, and hence the cooler areas of the body tend to be affected.

Symptoms of leprosy

As mentioned, leprosy progresses slowly, and the symptoms tend to be of a subtle nature and are not detected easily. Moreover, by the time the classic symptoms occur, the disease might already have reached an extreme stage. The common symptoms include:

Treatment of leprosy

Most cases of leprosy are generally treated with the help of antibiotics. The nature and stage of the disease determines the dosage and duration for which the drugs would be administered. According to experts, antibiotic treatment is prescribed for about 6-12 months, or more in some cases. Also, it is known that, whatever damage that has been incurred by the body because of the condition, before the administration of antibiotics, is irreversible.

Avoiding contact with the fluids of the patient is considered to be the only way to prevent the spread of infection to others. If antibiotics are administered properly, then the risk of spreading the disease to others reduces by a great extent. However, it should also be known, that unlike what most people think this disease is not highly contagious. In fact, about 95% of exposures result in no disease.

As of now, there is no vaccine which can provide immunity against leprosy. However, proper usage of drugs is highly effective in treating this disease. The World Health Organisation has made diligent efforts to reduce the incidence of leprosy. There has been a significant reduction in the number of leprosy cases.

Nice information shared. Efforts should be made to treat the patients of this disease as they are high in number.

I was just 10 years old when I had a Leprosy, I went through the treatment and the results are getting well day by day.
