Leishmaniasis, which is caused by protozoan parasites, which originate in a certain species of sand fly can cause skin sores, which don't actually appear until weeks or even months after one is bitten. The disease can also cause spleen and liver damage, fever and anemia, all of which can again not occur in one until months or sometimes year after the original bite.
Human leishmaniasis is a disease caused by parasites of the Leishmania genus, transmitted through the bites of infected sandflies. It can manifest as cutaneous, mucocutaneous, or visceral forms, with symptoms ranging from skin ulcers to organ damage, and can be fatal if left untreated. Leishmaniasis is mainly found in tropical and subtropical regions, affecting millions of people worldwide each year.
The common name for leishmaniasis is "sandfly disease." It is caused by parasites of the genus Leishmania and is transmitted to humans through the bites of infected sandflies. The disease can manifest in different forms, including cutaneous, mucocutaneous, and visceral leishmaniasis, depending on the species of the parasite and the immune response of the host.
The body's immune system apparently fails to battle the protozoa, which are free to spread throughout. The characteristic lesions resemble those of the dread biblical disease, leprosy.
