How long after exposure until you see the first symptom of kala azar?

Leishmaniasis. There are different forms of leishmaniasis. Cutaneous leishmaniasis affects the skin and mucous membranes. Skin sores usually start at the site of the sandfly bite. In a few people, sores may develop on mucous membranes. Systemic, or visceral, leishmaniasis affects the entire body. This form occurs 2 - 8 months after a person is bitten by the sandfly.
