“…The relevance of these findings stems from the unprecedented nature of these records, indicating a recent spread of the disease, and from the constant notification of autochthonous cases of VL in the metropolitan region, Cuiabá, and Várzea Grande, as well as in smaller municipalities. These findings, allied to earlier investigations, indicate the presence of the disease in different biomes that make up the State ( Queiroz et al, 2012 ; Thies et al, 2018 ; Brito et al, 2019 ; Menegatti et al, 2020 ).…”

Visceral leishmaniasis (VL) is considered a globally neglected disease. To address the problem of VL endemic to Brazil, the Visceral Leishmaniasis Control Program (VLCP) was created, which recommends the development of health surveillance actions such as the identification of human and canine cases, vector control and prevention of disease. We aimed to investigate the epidemiological situation of VL in municipalities of the State of Mato Grosso (MT) and assess the execution of VLCP activities. Data on human cases were obtained from the Information System for Notifiable Diseases (SINAN), and data from entomological and canine inquiry were provided by the State’s Health Department. Analyzes from the period 2019 - 2021 recorded 30 cases of human VL, distributed among 16 municipalities. Vectors were identified in 50% of the municipalities where entomological investigations were carried out, and the predominant specie was Lutzomyia longipalpis. A total of 15,585 dogs were subjected to serological examination, of which 18.91% tested seropositive for Leishmania infantum. However, it must be emphasized that only three municipalities conducted consecutive inquiries involving canine VL. Although VL is distributed widely throughout the State, only a few municipalities have undertaken the actions of the VLCP, thus highlighting the neglected status of the disease.

Introduction: The Visceral and American Cutaneous Leishmaniases are a public health problem in the Americas, in the municipality of Altos, state of Piauí, are considered endemic. Aim: To carry out a faunal survey of the phlebotomine species in the areas of transmission of visceral and cutaneous, both human and canine, leishmaniases, in the municipality of Altos, Piauí. Outlining: It was carried out through entomological survey, it encompassed capture, separation, identification, and analysis of phlebotomine species in determined regions in the municipality of Altos, Piauí, between August 2017 and July 2019. Results: The most found species was Lutzomyia longipalpis, with 1,399 sandflies captured, 1,299 males and 140 females. Some other species were also found, such as Nyssomyia whitmani, Lutzomyia dispar, Evandromyia evandroi. Implications: The research helps to provide data that can contribute to the formulation of surveillance and control actions for these vectors, enabling responsible entities to develop public policies to control leishmaniasis.

Visceral leishmaniasis is a disease caused by protozoa of the species Leishmania (Leishmania) infantum (syn = Leishmania chagasi) and Leishmania (Leishmania) donovani, which are transmitted by hematophagous insects of the genera Lutzomyia and Phlebotomus. The domestic dog (Canis familiaris) is considered the main urban reservoir of the parasite due to the high parasite load on its skin, serving as a source of infection for sandfly vectors and, consequently, perpetuating the disease in the urban environment. Some factors are considered important in the perpetuation and spread of canine visceral leishmaniasis (CVL) in urban areas, such as stray dogs, with their errant behavior, and houses that have backyards with trees, shade, and organic materials, creating an attractive environment for sandfly vectors. CVL is found in approximately 50 countries, with the number of infected dogs reaching millions. However, due to the difficulty of controlling and diagnosing the disease, the number of infected animals could be even greater. In the four continents endemic for CVL, there are reports of disease expansion in endemic countries such as Brazil, Italy, Morocco, and Tunisia, as well as in areas where CVL is not endemic, for example, Uruguay. Socio-environmental factors, such as migration, drought, deforestation, and global warming, have been pointed out as reasons for the expansion into areas where it had been absent. Thus, the objective of this review is to address (i) the distribution of CVL in endemic areas, (ii) the role of the dog in the visceral leishmaniasis epidemiology and the factors that influence dog infection and the spread of the disease, and (iii) the challenges faced in the control of CVL.
