Q. What are the symptoms of leprosy?
Doctor Answer is medically reviewed by SecondMedic medical review team.
Leprosy, also known as Hansen's disease, is a chronic bacterial infection caused by the bacterium Mycobacterium leprae. It primarily affects the skin, peripheral nerves, and mucous membranes. Leprosy can present with a wide range of symptoms, and the severity of the disease can vary greatly from person to person. The symptoms of leprosy typically develop slowly over a period of several years and can include:
Skin Lesions: Leprosy often first manifests as skin lesions, which may appear as discolored patches with decreased sensation. These patches can be pale, reddish, or copper-colored and may be raised or flat.
Numbness or Loss of Sensation: Leprosy can lead to a loss of sensation in the affected areas, making it difficult for individuals to feel pain, heat, or cold. This can result in injuries or burns going unnoticed.
Muscle Weakness: Over time, leprosy can cause muscle weakness and atrophy (shrinkage) in the hands and feet, which can lead to deformities and disabilities.
Thickened Nerves: Leprosy can affect the peripheral nerves, causing them to become thickened and tender. These nerve involvement can lead to various complications.
Eye Problems: Leprosy can affect the eyes, leading to symptoms such as dryness, reduced blinking reflex, and, in severe cases, blindness.
Nasal Congestion: Some individuals with leprosy may experience chronic nasal congestion and nosebleeds due to mucous membrane involvement.
Loss of Eyebrows and Lashes: Leprosy can cause the loss of eyebrows and eyelashes, which can contribute to eye-related problems.
Ulcers and Skin Disfigurement: Untreated leprosy can result in the formation of skin ulcers and nodules, leading to disfigurement and functional impairment.
It's important to note that leprosy is not highly contagious, and it is primarily spread through prolonged close contact with an untreated, infectious individual. The disease is curable with multidrug therapy (MDT) provided by healthcare professionals. Early diagnosis and treatment are crucial to preventing complications and reducing the spread of the disease. If you suspect you or someone you know may have leprosy, it is essential to seek medical evaluation and treatment promptly.
