Leprosy is a chronic infectious disease caused by the bacterium Mycobacterium Leprae. To date, the exact transmission mechanism of leprosy has not been clearly defined. However, in recent times, statistics show that the disease can be transmitted through contact between sick and healthy people, especially the trend of respiratory leprosy transmission is increasing sharply.
In addition, the disease can also be transmitted through insects – vectors. Leprosy most commonly affects the nerves of the extremities, skin, nasal mucosa, and upper respiratory tract, causing skin ulcers, nerve damage, and muscle weakness. If not detected and treated in time, the disease can cause body disfigurement and even permanent disability. In addition, a number of other complications can also occur if this disease is not intervened:
Hair loss and hair loss, especially eyebrows, eyelashes... Chronic nasal congestion, nosebleeds and collapse nasal septum. Iritis . Increased risk of glaucoma - one of the eye diseases that damage the optic nerve, causing blindness. CKD . Reduced physiological capacity... According to the Centers for Disease Control and Prevention (CDC), leprosy occurs especially in countries with tropical or subtropical climates.

Usually, leprosy can be diagnosed based on clinical signs of the disease. In addition, the doctor will perform some biopsies such as taking a piece of skin/nerve from the patient and sending it in for testing.
Skin tests to diagnose leprosy will also be done to determine the type of disease by injecting a small amount of the causative (but inactivated) bacteria into the skin, typically in the upper forearm. People with grade 1 or grade 2 leprosy will test positive at the injection site.
