“…CVL is generally more prevalent in rural areas than in urban areas (Amóra et al 2006, Almeida et al 2012). However, in some regions changes in this pattern occurred, with the expansion of the disease to urban areas (França-Silva et al 2003, Guimarães et al 2017, which was also observed in the present study. This urbanization process has occurred since the 1980s and is associated with several phenomena such as the migration of humans and their pets from the countryside to the urban area (associated with disorderly occupation and precarious living conditions), climate change and deforestation, in addition to the dispersion and adaptation of the vector (WHO 2002, Costa 2008, Salomón et al 2015.…”

The objective of this study was to estimate the prevalence of canine visceral leishmaniasis (CVL) and to identify the differences in associated factors to its occurrence in urban area and countrysides in the municipality of Santa Luzia located in the semi-arid region of Paraíba. In the years 2015 and 2016, 779 blood samples from dogs were collected. The prevalence was determined by three serological techniques, ELISA-S7® Kit, DPP® Rapid Test and EIE-LVC® Kit, considering positive the samples that reacted in at least two assays. Associated factors were determined by univariate and multivariate analyzes of the guardians’ responses to the epidemiological questionnaire. The prevalence of anti-Leishmania infantum antibodies in the studied municipality was 15.00% (117/779), being higher in the urban area (15.20%) than in the countryside (13.60%). The neighborhood with the highest prevalence was Frei Damião with 26.40% (33/125), being considered a hotspot (OR 1.245, p=0.007). Other associated factors were the semi-domiciliary breeding (OR 1.798, p=0.025), in the urban area, and hunting dog (OR 18.505, p=0.016), contact with cattle (OR 17.298, p=0.022) and environment where the dog is raised (OR 4.802, p=0.024) in the countryside. In the municipality of Santa Luzia, the prevalence of canine visceral leishmaniasis is high and the disease is widely distributed. Epidemiological differences between urban area and the countryside could be observed demonstrating the need for more adequate control measures for each locality and proving the urbanization process.

“…In the present study, the prevalence of canine Leishmania infection was higher in the rural area (26.6%), and this variable was considered a risk factor for the occurrence of the disease, reinforcing the old dynamics of endemicity of visceral leishmaniasis in rural areas (Amóra et al, 2006). Although the disease has expanded to urbanized areas since 1950 (Figueiredo et al, 2012;Guimarães et al, 2017), this factor does not apply to the municipality studied, as the area is small and there is a close contact between the urban and rural areas.…”

Visceral leishmaniasis (VL) is a zoonosis with a worldwide distribution that has a major impact on public health. The aim of this study was to verify the prevalence of canine infection by Leishmania infantum, the factors associated with the infection and its spatial distribution in the municipality of Mãe D’Água, in the Sertão region of Paraíba State, Northeast Brazil. Blood samples were collected from 150 dogs for diagnosis by the DPP®, ELISA-S7®, ELISA-EIE® and qPCR assays. The prevalence was calculated considering the positivity in at least two tests. SaTScan® was used for spatial analysis. The prevalence of canine infection with Leishmania was 18.6% (28/150), with the rural area being identified as a risk factor (Odds Ratio (OR) = 2.93). The permanence of the dog loose during the night (OR = 0.33) and deworming (OR = 0.30) were identified as protective factors. A risk cluster was formed in the northern region of the urban area. Mãe D’Água showed a pattern of active transmission in the rural area, but VL control measures also need to be carried out in the urban area to prevent human cases and the spread of the disease in the risk zone.

“… 14 In order to understand the epidemiology of canine leishmaniasis, many studies were dedicated to serological investigation, where they found the presence of Leishmania antibodies in the analyzed samples. 15 – 21 Other studies showed the participation of dogs in the process of urbanization 22 , 23 and resurgence of leishmaniasis, 22 as well as suggesting that the disease is expanding in urban areas, with an exponential increase of positivity within dogs. 24 …”

This work describes a systematic and bibliometric review of the factors that contribute to the expansion of leishmaniasis in urban areas. Three scientific databases were used: Scientific Electronic Library (Sci ELO), Scopus and Web of Science, encompassing all original and review articles between 1959 and 2021. Three descriptors were used: “leishmaniasis” AND “urban” AND “rural.” Planning, execution, summarization, and selection processes were performed using StArt ( State of the Art through Systematic Review) software. We obtained a total of 304 articles, 60 of which concerned canine leishmaniasis. The factors associated with the expansion of leishmaniasis in urban areas are interrelated, including socioenvironmental and economic complexity, the type of leishmaniasis, the reservoirs, vectors, deforestation, disorderly occupation of space, poor sanitary conditions, and human migration trends. A lack of diagnosis and underreporting of cases in some regions may reflect the increase of cases seen in urban areas. A majority ( n = 121) of studies were conducted in Brazil, followed by Iran ( n = 43). In relation to publications; in general, output has increased over the years, particularly in 2021. The majority of published studies were in the area of epidemiology ( n = 158).
