Children are more susceptible to leprosy than are the adults. Bacteria gain entrance into the human beings through the nasal mucosa or through skin.

Types : Two types –

  1. Tuberculoid, granuloma formation in the skin and nerves, less bacilli; giant cells, epitheloid cells are present, chronic course, less infectious.
  2. Cutaneous nodules; popular, and diffuse infiltrative lesions, plenty of lepra bacilli and lepra cell.

Cardinal signs of Leprosy:

  1. Thickened nerves.
  2. Presence of acid-fast bacilli (by examination of nasal scrapings or nodule under microscope).
