What is leprosy?
What causes leprosy?
Leprosy (Hansen's Disease) is caused by a bacillus (germ) called Mycobacterium leprae (M. leprae). It mainly affects the skin, nerves and eyes.
Leprosy is not a highly contagious disease, it has a long incubation period (the period between infection and seeing symptoms). For leprosy, this is five years on average, but can be anything between one year and 20 years. During the incubation period, an infected person does not have any visible signs or symptoms but may already be infectious.
Anyone can be diagnosed with leprosy, but 90-95 percent of people never develop leprosy, however much they are exposed to M. leprae.Find out more about how leprosy is transmitted
What are the signs and symptoms of leprosy?
- Skin patches which are a different colour from the rest of your skin (in brown/black skin the patches are lighter; in light-skinned people the patches are reddish in colour) and with no feeling (meaning that it is numb and has no sensation)
- Loss of feeling or numbness of the hands and feet.
- Muscle weakness or paralysis - struggling to hold things in your hands, unable to lift your foot up so that your toes are pointing upwards; unable to close your eyes,
If you notice any of these - please go to the nearest health centre or hospital.Find out what leprosy looks like with our photo gallery
How is leprosy treated?
Leprosy is curable with Multi-Drug Therapy (MDT) - a combination of three antibiotics that has been used to treat leprosy for decades. MDT is highly effective in killing M. leprae and people are no longer infectious a few days after starting treatment. MDT is the only effective treatment for leprosy and you should not consider herbal remedies or any other forms of treatment.
Multi-Drug Therapy (MDT) is given to people diagnosed with leprosy completely free of cost.
