“…To better understand the differences in the spatial distribution of leprosy, studies have been conducted in Brazil; however, the scientific literature is not proportional to the intensity of the disease (8) . Of the various analytical methods used, the identification of clusters is considered a potential approach, since it does not disregard the silent areas due to a low detection effort or favors municipalities with a larger number of cases due to the size of their population and not the higher risk (9) .…”

Objectives: to identify high-risk areas of leprosy in Brazil from 2001 to 2015. Methods: this is an ecological study of spatial analysis based on Brazilian municipalities. Spatial scan statistics were used to identify spatial clustering and measure the relative risk from the annual detection rate of new cases of leprosy. By criterion based on the Gini index, only secondary clusters were considered. Results: spatial scan statistics detected 26 clusters, in which the detection rate was 59.19 cases per 100 thousand inhabitants, while in the remainder of the country it was 11.76. Large part of the cluster area is located in the Legal Amazon. These groups included only 21.34% of the total population, but 60.40% of the new cases of the disease. Conclusions: Leprosy remains concentrated in some areas, showing the need for control programs to intensify actions in these municipalities.

“…Spatial-temporal analysis enables a better understanding of the hyperendemic situation of the disease in addition to assisting the creation, implementation and reorientation of control measures. This type of study has become common for leprosy control in several regions of Brazil 14,15,16,17,18 .…”

This study aimed to identify the distribution pattern of leprosy in a hyperendemic municipality in Brazil and determine its relationship with the clinico-epidemiological situation over 11 years. The geographic information system, MapInfo, spatial scan statistics and the Moran I index were used to analyze new cases. The digital cartographic base was used to map clusters of new paucibacillary and multibacillary cases and cases in minors under 15 years old. Socioeconomic indicators are shown using the choropleth mapping technique. A reduction in the detection coefficient, increases in high-risk spatial clusters, marked changes in the distribution of high-risk and low-risk clusters, and high-risk clusters of minors under 15 years old were observed from 2006 to 2010, showing recent illness, the presence of active foci, and overlapping of high-risk clusters of multibacillary infection in minors under 15 years old. Leprosy remains a public health problem in Rondonópolis, Mato Grosso State; the high-risk areas require an intensification of control measures and active search strategies to detect new cases.

“…In relation to ethnicity, there was a predominance of leprosy in brown color individuals, which reflects the historical process of colonization in Brazil and its miscegenation, migratory movements, dynamics of territorial occupation and spatial organization, as pointed out by other studies (Lima et al, 2009;Lima et al, 2010;Silva et al, 2010;Silva et al, 2017). The most prevalent age group was between 20 and 40 years old, which is in accordance with another study also carried out in the city of Anápolis (Nascimento et al, 2007).…”

Leprosy is a chronic bacterial granulomatous disease that affects skin and peripheral nerves and shows slow progression. This study was to trace the epidemiological and clinical profile of leprosy among cases reported in the Information System for Notifiable Diseases in Anápolis, Goiás, Central-West region of Brazil. This is an epidemiological, descriptive and a cross-sectional study. Between January 2011 and December 2016, assistance was provided to 484 patients with leprosy. Among the patients, 59.5% male and the most prevalent age group was between 20-40 years old. Brown population in 47.3% of the cases and 51.7% of the patients completed elementary education. The majority of the cases were multibacillary and Virchowian clinical forms were prevalent, with zero degree of disability detected in 79.56% of the patients. There was no death due to leprosy during the study period. The epidemiological data indicates that a greater integration between the population and primary care must be encouraged, a crucial step for health education and strategies in order to combat the disease.
