Leishmaniasis is a disease caused by what is known as “protozoan parasites”. Protozoa are microscopic, one-celled organisms that are able to multiply in humans, causing serious infections. Leishmansis is transmitted to humans by the bite of infected female sandflies.
The worst form of the disease is called Visceral Leishmaniasis (VL), and it is endemic in more than 80 countries. People usually suffer from irregular bouts of fever, weight loss, enlargement of the spleen and liver, and anaemia.
