Study Notes
Causes and Transmission of Leprosy
- The primary cause of leprosy is Mycobacterium leprae (M. leprae) bacteria.
- Leprosy is primarily spread between people through respiratory droplets, such as those produced by coughing or sneezing.
Development of Leprosy
- Around 95% of people who contract M. leprae do not develop the disease, suggesting that genetic factors and immune function play a significant role.
Nerve Damage and Consequences
- Nerve damage caused by leprosy can lead to disability, discoloration, disfiguration, and blindness if left untreated.
- The primary cause of nerve damage in leprosy is the immune system's response to M. leprae, which can cause inflammation and damage to nerve fibers.
Incubation Period
- It can take anywhere from a few months to 20 years or more for symptoms of leproy to occur in some people, making it a challenging disease to diagnose.
Mode of Spread
- The primary mode of spread of leprosy between people is through close, prolonged contact with an infected person, usually through respiratory droplets.
