Leishmaniasis is transmitted by the bite of infected female phlebotomine sandflies. The sandflies inject the infective stage (i.e., promastigotes) from their proboscis during blood meals . Promastigotes that reach the puncture wound are phagocytized by macrophages and other types of mononuclear phagocytic cells.

Non-drug therapy including cauterization, surgical excision, cryotherapy, but the simplest of these treatments is the local application of heat. As Leishmania species are heat labile, this topical therapy has been proven effective in placebo-controlled studies.

Where do Leishmania Amastigotes transform Promastigotes?
Sand flies become infected by ingesting infected cells during blood meals ( , ). In sand flies, amastigotes transform into promastigotes, develop in the gut (in the hindgut for leishmanial organisms in the Viannia subgenus; in the midgut for organisms in the Leishmania subgenus), and migrate to the proboscis .
