Health is a common aspect in most cultures, infact all communities have their concepts of health as a part of their culture.

WHO defines health as “a state of complete physical, mental and social wellbeing and not merely an absence of disease or infirmity.” Health and disease lie alongside and there is no single cut off point. Diseases may be of many types and are categorized differently. Leprosy is a chronic disease and is probably the oldest disease known to mankind.

It’s an infectious disease which mainly affects the peripheral nerves; it majorly affects the skin, muscles, eyes, bones, testes and internal organs. It is characterized by hypo pigmented patches, partial or total loss of sensation in the affected areas and presence of thickened nerves. Leprosy is caused by M.leprae. They occur characteristically in clumps or bundles. Its diagnosis is through interrogation, physical examination through inspection of the body, testing loss of sensation in the skin patches. Chemotherapy alone is not likely to solve the whole problem of leprosy and leprosy is a long term activity, therefore planning and programme management is essential. The other disease is Hepatitis B which is an acute systematic infection with major pathology in the liver, caused by hepatitis B virus and transmitted usually by the parenteral route.

Hepatitis B is endemic throughout the world. It has been estimated that more than 2 billion people are infected with the disease globally.HBV occurs in three morphological forms in the serum of a patient (a)small particles with an average diameter (b)tubules of varying length and diameter and (c) the Dane particle which corresponds morphologically to hepatitis. Many adults have many or no symptoms, some of the symptoms are loss of appetite, malaise i.e. feeling of ill health, dark urine, abdominal pain and jaundice. Few patients experience severe course of illness, and may collapse with fatigue and develop swelling in the abdomen.
