Epidemiological aspects of Leishmaniasis in the Pantanal region of Mato Grosso

Abstract

Abstract Leishmaniasis is a disease caused by the protozoan Leishmania parasite that is disseminated by some species of sandflies and hosted by a variety of reservoirs. The objective of the present study was to evaluate the epidemiological situation of leishmaniasis in the municipalities of the Mato Grosso Pantanal. Human data were obtained from the Information System of Notifiable Diseases, and the canine and vector results from the State Department of Health of Mato Grosso. Between 2007 and 2016, 10 cases of visceral leishmaniasis and 499 cases of tegumentary leishmaniasis were identified in the Pantanal region. The surveillance studies regarding the canine reservoir demonstrated that the parasite was present in six of the seven municipalities. Vectors of visceral leishmaniasis were present in five municipalities and vectors of tegumentary leishmaniasis in six. Enhancement of services aimed at controlling this disease is fundamental to prevent an increase in the number of cases in the region.
