==Overview==
Human leishmanial infections can result in 2 main forms of disease, cutaneous leishmaniasis and visceral leishmaniasis ([[kala-azar]]).  The factors determining the form of disease include leishmanial species, geographic location, and immune response of the host.
==Symptoms==
===Cutaneous leishmaniasis===
*Cutaneous leishmaniasis is characterized by one or more cutaneous lesions on areas where sandflies have fed. 
*Persons who have cutaneous leishmaniasis have one or more sores on their skin. 
*The sores can change in size and appearance over time.  They often end up looking somewhat like a volcano, with a raised edge and central crater. 
*A scab covers some sores. 
*The sores can be painless or painful. 
*Some people have swollen glands near the sores (for example, in the armpit if the sores are on the arm or hand).
*People with cutaneous leishmaniasis usually develop skin sores within a few weeks (sometimes as long as months) of when they were bitten.
===Visceral leishmaniasis===
*Persons who have ''visceral leishmaniasis'' usually have [[fever]], [[weight loss]], and an enlarged spleen and liver (usually the spleen is bigger than the liver).  Some patients have swollen glands. 
*People with visceral leishmaniasis usually become sick within several months (rarely as long as years) of when they were bitten.
*The symptoms of leishmaniasis are skin sores which erupt weeks to months after the person affected is bitten by sand flies.
*Other consequences, which can become manifest anywhere from a few months to years after infection, include fever, damage to the [[spleen]] and [[liver]], and [[anaemia]].

Overview

Human leishmanial infections can result in 2 main forms of disease, cutaneous leishmaniasis and visceral leishmaniasis (kala-azar). The factors determining the form of disease include leishmanial species, geographic location, and immune response of the host.

Symptoms

Cutaneous leishmaniasis

  • Cutaneous leishmaniasis is characterized by one or more cutaneous lesions on areas where sandflies have fed.
  • Persons who have cutaneous leishmaniasis have one or more sores on their skin.
  • The sores can change in size and appearance over time. They often end up looking somewhat like a volcano, with a raised edge and central crater.
  • A scab covers some sores.
  • The sores can be painless or painful.
  • Some people have swollen glands near the sores (for example, in the armpit if the sores are on the arm or hand).
  • People with cutaneous leishmaniasis usually develop skin sores within a few weeks (sometimes as long as months) of when they were bitten.

Visceral leishmaniasis

  • Persons who have visceral leishmaniasis usually have fever, weight loss, and an enlarged spleen and liver (usually the spleen is bigger than the liver). Some patients have swollen glands.
  • People with visceral leishmaniasis usually become sick within several months (rarely as long as years) of when they were bitten.
  • The symptoms of leishmaniasis are skin sores which erupt weeks to months after the person affected is bitten by sand flies.
  • Other consequences, which can become manifest anywhere from a few months to years after infection, include fever, damage to the spleen and liver, and anaemia.
