```Leishmaniasis is mainly spread by sand flies. Depending on the parasite species, symptoms of infection may include large skin lesions, fever, swelling of the spleen and liver,
Bolivia and Belgium examined data on 97 leishmaniasis patients. These were gathered through a project on drug resistance,
leishmaniasis is common in people who work in agriculture and forestry, said lead author Vanessa Adaui, Ph d,
treatment failure is a major obstacle to the control of infectious diseases like leishmaniasis, said Dujardin. t is of uppermost importance to understand the factors contributing to this failure to better tackle it.
But the failure rate was only 24 percent in patients with parasites that were free of the virus. The standard treatment for leishmaniasis differs based on the parasite species that causes the infection
The scientists are investigating how viral infection makes leishmaniasis more difficult to cure. According to Beverley, the parasites infected with the virus may be interacting with patientsimmune systems in a way that disrupts treatment.
