Hi, 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 manifest anywhere from a few months to years after infection, include fever, damage to the spleen and liver, and anemia. Visceral leishmaniasis – the most serious form and potentially fatal if untreated. Cutaneous leishmaniasis – the most common form which causes a sore at the bite site, which heals in a few months to a year, leaving an unpleasant looking scar. This form can progress to any of the other three forms. Diffuse cutaneous leishmaniasis – this form produces widespread skin lesions which resemble leprosy and is particularly difficult to treat. Mucocutaneous leishmaniasis – commences with skin ulcers which spread causing tissue damage, to the nose and mouth.
