What is Leishmaniasis and How is it Transmitted?

Leishmaniasis is a parasitic disease caused by Leishmania parasites, which are transmitted through the bites of infected sandflies. There are different forms of leishmaniasis, including cutaneous leishmaniasis, mucocutaneous leishmaniasis, and visceral leishmaniasis.
