  1. 1. The Study of Leprosy<br />By Chris Johnson<br />
  2. 2. How is it caused?<br />Leprosy, also known as Hansen’s disease is caused by the bacteria called Mycobacterium leprae and Mycobacterium leprae<br />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<br />
  3. 3. Who can get it?<br />Children are more prone to get it than adults<br />There is no specific group that contracts the disease but the top 3 countries with the most reported cases are; <br />1. India<br />2. Brazil<br />3. Burma<br />
  4. 4. Etiology <br />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<br />The primary sign is skin lesions that are usually lighter than your normal skin tone<br />These lesions have a “decreased sensation to touch, heat or pain”<br />Some symptoms are (see next slide)<br />
  5. 5. Symptoms and Signs Continued<br />The lesions persist for weeks and months<br />Left untreated, leprosy can cause permanent damage to the skin, nerves, eyes and limbs<br />Symptoms include; dry scalp, muscle weakness, and eye problems<br /> If diagnosed early, you can avoid nerve damage and disability<br /> For 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<br />
  6. 6. Pathophysiology<br />It is chronic<br />Genetics are thought to play a role in contracting the disease<br />Due 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<br />Your skin becomes infected with the lesions but the disease is at it’s worst when left untreated<br />It can cause permanent nerve damage<br />It can also cause damage to your muscles and eyes causing your muscles to weaken and your eyesight to falter <br />
  7. 7. Prognosis and Treatment<br />The earlier you catch the disease the better. This is to avoid permanent damage<br />After a few weeks of treatment you can become noninfectious (not contagious)<br />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<br />There are many leprosy colonies around the world to isolate and limit the disease from spreading<br />
