“…El control de la leptospirosis canina dependerá de la higiene del entorno, mediante la eliminación de los roedores, control de reservorios, como también manteniendo un control sanitario en las mascotas (28). El uso de sistemas de georeferencia (SIG) y el análisis estadístico espacial, son métodos que en el campo de la salud permiten establecer y asociar ambientes y reproducción de la leptospirosis (29), ya que está íntimamente relacionado las características ecológicas de la leptospirosis con el medio ambiente, dando un análisis completo y estableciendo las zonas de mayor incidencia de la enfermedad permitiendo la participación de los distintos profesionales en el ámbito de salud humana y animal para así tomar medidas de prevención (29).…”

Introducción: La leptospirosis como una enfermedad de carácter zoonótico en los últimos años ha sido de gran preocupación en el mundo siendo una enfermedad de declaración ante la OMS a medida del pasar de los años en ciertas zonas preferentemente las ligadas a climas tropicales y subtropicales se ha establecido que tiene un aumento su presencia especialmente en estaciones lluviosas, esta bacteria causa enfermedad en varios pacientes sea animales o humanos, y por esa causa en importante conocer su distribución y propagación. Objetivos: El objetivo principal de la presente investigación es tener un documento actualizado sobre la leptospirosis su potencial zoonosis y el estado actual en el país Ecuador. Determinar la leptospirosis como una enfermedad zoonótica de importancia epidemiológica a nivel nacional. Conocer la distribución de la leptospirosis en cuánto a sus investigaciones a nivel nacional. Metodología: Bibliográfica para leptospirosis como enfermedad de importancia zoonótica para elaborar un documento con una actualización de esta importante, se encontraron 23 publicaciones, pero se tomaron en cuenta 13 esto con la finalidad de conocer la situación actual y real de la leptospirosis en el Ecuador. Resultados: Esta investigación se apreció que los casos positivos para leptospirosis utilizando cualquier técnica diagnostica se obtuvieron diversos resultados los cuales en promedio fue de 58.04% de prevalencia siendo la región costa la que presenta la mayoría de los casos. Conclusiones: La leptospirosis es una enfermedad que afecta a varias especies incluido al humano a nivel mundial, pero en nuestro país es sub considerada, se puede concluir que en todas las investigaciones que se reportan existe una alta prevalencia y la región más estudiada es la costa.

“…Therefore, we consider that the analysis of real-time data on the incidence of confirmed leptospirosis cases collected from information systems derived from the official surveillance of the disease in Brazil can contribute to elucidate the difficulties in disease control and to understand the dynamics of occurrence of this endemic disease in the country. These observations can be used as tools to help healthcare managers to design appropriate prevention strategies and promote public health safety efforts [ 12 , 13 ].…”

Spatial and temporal dynamics of leptospirosis in South Brazil: A forecasting and nonlinear regression analysis

et al. 2023

Although leptospirosis is endemic in most Brazilian regions, South Brazil shows the highest morbidity and mortality rates in the country. The present study aimed to analyze the spatial and temporal dynamics of leptospirosis cases in South Brazil to identify the temporal trends and high-risk areas for transmission and to propose a model to predict the disease incidence. An ecological study of leptospirosis cases in the 497 municipalities of the state of Rio Grande do Sul, Brazil, was conducted from 2007 to 2019. The spatial distribution of disease incidence in southern Rio Grande do Sul municipalities was evaluated, and a high incidence of the disease was identified using the hotspot density technique. The trend of leptospirosis over the study period was evaluated by time series analyses using a generalized additive model and a seasonal autoregressive integrated moving average model to predict its future incidence. The highest incidence was recorded in the Centro Oriental Rio Grandense and metropolitan of Porto Alegre mesoregions, which were also identified as clusters with a high incidence and high risk of contagion. The analysis of the incidence temporal series identified peaks in the years 2011, 2014, and 2019. The SARIMA model predicted a decline in incidence in the first half of 2020, followed by an increase in the second half. Thus, the developed model proved to be adequate for predicting leptospirosis incidence and can be used as a tool for epidemiological analyses and healthcare services.Temporal and spatial clustering of leptospirosis cases highlights the demand for intersectorial surveillance and community control policies, with a focus on reducing the disparity among municipalities in Brazil.

“…In the fight against CS, its epidemiological scenery should first be determined. In this context, spatial analysis techniques are useful tools to visualise the areas with higher epidemiological pressure and associate the studied phenomenon with the sociopolitical and economic factors that contribute to the problem 11 12. The results generated by the spatial analysis provide information to health authorities to evaluate the already implemented strategies and to possibly implement new ones.…”

ObjectiveTo analysis the epidemiological scenery of the congenital syphilis (CS) in Brazil employing spatial analysis techniques.DesignEcological study.SettingsThis study was conducted in BrazilSampleA total of 151 601 CS cases notified to the Diseases and Notification Information System from 2007 to 2018 from children aged 0–23 months and born from mothers living in Brazil were included in this study.Primary outcome measuresThe CS incidence rates were calculated by triad (2007–2010, 2011–2014 and 2015–2018) for all Brazilian municipalities following the Boxcox transformation to remove the discrepant values. The transformed rates were analysed through the spatial autocorrelation of Moran, Kernel density estimative and spatial scan.ResultsFrom 2007 to 2018, the CS incidence rates increased in all Brazilian regions. The CS spread towards the interior of Brazil, and a higher expansion was noticed between 2015 and 2018. The municipalities that were greatly affected by the CS were those having a high migration of people, such as the ones bordering other countries and the touristic cities. Recife, Campo Grande, Rio de Janeiro, Porto Alegre and Manaus were the capitals with the greatest spatial and spatiotemporal risk.ConclusionThis study provides assistance to health authorities to fight CS in Brazil. More investment is necessary in prenatal care quality focusing on pregnant women and their partners to guarantee their full access to preventive resources against sexually transmitted infections.
