Conceptual framework on leprosy

Webster
(1997) viewed leprosy as a contagious disease caused by the bacterium called
mycobacterium leprae, it affects the skin, mucous membranes and nerves, causing
discoloration and lumps on the skin and in severe cases, disfigurement and
deformities.
World
Health Organization (1993) see leprosy as a chronic infectious disease caused
by a bacterial mycobacterium leprae, it also know as hansen’s disease named
after its discover Gerhard Henrick Armeuer Itansen who said the disease affect
the peripheral nerves, mucosa of the upper respiratory tracts and also the eyes
apart from some other structures.

The
Leprosy Mission International (1961) explained that leprosy is a medical
condition also know as Hansen’s disease caused by mycobacterium. It is an
airborne infection, it can be spread by sneezing droplet from an infected
person, coughing and full of droplet from the mouth of an infected person. The
first outward sign of leprosy is a patch on the skin usually associated with
loss of feeding.
American
Heritage (2005) see leprosy as a chronic and infectious disease, characterized
by patches of altered skin and nerves tissue (lesions) that gradually spread to
cause muscle weakness, deformities, and paralysis. Some forms of antibiotics
are now used to treat this disease, and plastic surgery can help correct the
deformities it causes. Also called Hansen’s disease.
Leprosy
has been well know since ancient times, when widespread fear of those afflicted
with the disease caused them to be treated outcasts. Today the term leper is
often used to refer to a person excluded from society.
They
further said it is a slowly progressive, chronic infections disease caused by
the bacterium mycobacterium leprae, that damages nerves, skin and mucous
membranes, and can lead to loss of sensation, paralysis gangrene, and deformity
if untreated.
Akinsola
(1993) said leprosy (Hansen’s Disease) is a chronic infectious disease that
primarily affects the peripheral nerves, skin, upper respiratory tract, eyes,
and nasal mucosa. The disease is caused by a bacillus (rod-shaped) bacterium
known as mycobacterium leprae.
He
further said the disease was discovered by G.A. Hansen in 1873, is a
slow-growing intracellular pathogen that cannot live outside its hos because it
can only be grown in animals, not in a laboratory, it is more difficult to
study than other bacteria. Anmadillos and Immuno compromised mice are the two
primary sources for growing the bacteria for research purposes. He said another
factor complicating studies of leprosy is that in leprae (multiplies slowly),
and symptoms can take as long as 20 years to appear, Amadillos are the only
animals other than humans that have been found to become naturally infected
with the disease.
World
Health Organization (2010) viewed leprosy as a chronic disease caused by a
bacillus, mycobacterium leprae. Official figures show that more than 213,000
people mainly in Asia and Africa are infected with approximately 249,000 new
cases reported in 2008. in leprae multiplies very slowly and the incubation
period of the disease is about five year symptoms can take as long as 20 years
to appear. They further stated that leprosy is not highly infectious. It is
transmitted through (via) droplets from the nose and mouth, during close and
frequent contacts with untreated cases.
Untreated
leprosy can cause progressive permanent damage to the skin, nerves, limbs and
eyes. Early diagnosis and treatment with multidrug therapy (MDT) remain the key
elements in eliminating the disease as a public health concern.
