A30.0: Indeterminate leprosy

You have leprosy.

Leprosy is caused by specific bacteria. These bacteria are probably transmitted by direct contact with sick people. After infection, it can take a very long time for symptoms to appear.

Typical spots form on the skin. These spots are usually brighter than the surrounding skin or slightly reddened. The skin can feel numb at these sites.

  • V: Tentative diagnosis
  • Z: Condition after
  • A: Excluded diagnosis
  • L: Left
  • R: Right
