The Study of LeprosyBy Chris Johnson
How is it caused?Leprosy, also known as Hansen’s disease is
caused by the bacteria called Mycobacterium leprae and Mycobacterium leprae
Scientists aren’t exactly sure how it it transmitted but believe it’s usually spread from person to person through respiratory droplets, so yes, it is communicable
Who can get it?Children are more prone to get it than adultsThere is no specific group that contracts the
disease but the top 3 countries with the most reported cases are;
1. India2. Brazil3. Burma
Etiology The incubation period is on average, between
3 to 5 years. In infants, it can only take a few weeks. The maximum recorded incubation period was 30 years
The primary sign is skin lesions that are usually lighter than your normal skin tone
These lesions have a “decreased sensation to touch, heat or pain”
Some symptoms are (see next slide)
Symptoms and Signs ContinuedThe lesions persist for weeks and monthsLeft untreated, leprosy can cause permanent
damage to the skin, nerves, eyes and limbsSymptoms include; dry scalp, muscle
weakness, and eye problems If diagnosed early, you can avoid nerve
damage and disabilityFor diagnosis, you can have a Leprosy Skin Test, a Skin Lesion Biopsy, or they can take a sample of your skin to test for bacteria
Pathophysiology It is chronicGenetics are thought to play a role in contracting the
diseaseDue to these genetic factors, only 5% of the population
is susceptible to the disease (The body is naturally immune to the bacteria that causes the illness
Your skin becomes infected with the lesions but the disease is at it’s worst when left untreated
It can cause permanent nerve damageIt can also cause damage to your muscles and eyes
causing your muscles to weaken and your eyesight to falter
Prognosis and TreatmentThe earlier you catch the disease the better. This is
to avoid permanent damageAfter a few weeks of treatment you can become
noninfectious (not contagious)There are multiple types of leprosy but the most
common are Pauci-bacillary leprosy, which is up to 5 lesions and you use rifampicin and daspone for up to 6 months. But if you have more than 5 lesion, you treat it with rifampicin, daspone AND clofazimine
There are many leprosy colonies around the world to isolate and limit the disease from spreading
