Leishmaniasis Photo Gallery: Vector, Reservoirs, Parasite

Leishmaniasis is a tropical disease transmitted by the bite of the phlebotomine sandfly, which transmits the Amastigotes leishmania parasite. It affects vast areas of the Americas and puts millions of people at risk. Those affected by it tend to be the most vulnerable, indigenous peoples and others living in isolated rural areas or the many poor living in poverty in shantytowns on the fringes of large cities where access to health services is scarce. In addition, certain animals can act as a reservoir, including the family pet.
