“…En la pasada década, el interés se concentró en definir las zonas geográficas donde la leptospirosis fue un problema de salud pública y un riesgo potencial para los visitantes (Pappas et al 2008). La magnitud de esta enfermedad infecciosa refleja alta endemicidad, principalmente en la región del Caribe (Batchelor et al 2012, CAREC 2008, Vega-Corredor et al 2014, en la región Central y Sur de América, en el Sureste de Asia y Oceanía (Pappas et al 2008). De acuerdo a esta recopilación de datos, los primeros cinco países con mayor incidencia de casos anuales de leptospirosis : "Análisis espacial y epidemiológico sobre leptospirosis humana en Puerto Rico, 1996", GeoFocus (Artículos), nº 21, p. 227-251.…”

“…Puerto Rico al ser parte de la región caribeña comparte características ambientales y climatológicas muy similares. Por lo tanto, es importante realizar estudios descriptivos que evalúen y analicen las variaciones geo-temporo-espaciales de la ocurrencia de leptospirosis con factores ambientales y climatológicos similares a la ubicación geográfica (Batchelor et al 2012, Vega-Corredor et al 2014.…”

“…A través de la herramienta "Spatial Statistics" de ArcGIS 10, se crearon centroides espaciales por cada tramo censal dentro de cada municipio. A cada centroide espacial se le asignó el número total de casos confirmados de leptospirosis como el número absoluto de casos para cada tramo censal (Vega-Corredor et al 2014). El uso de los tramos censales permitió un acercamiento más real para adjudicarle a cada centroide espacial el número de casos confirmados de leptospirosis.…”

RESUMENSe realizó un estudio ecológico sobre los casos confirmados de leptospirosis humana reportados al Sistema de Vigilancia del Departamento de Salud de Puerto Rico entre 1996 y 2014. El propósito principal fue evaluar la distribución espacial de la ocurrencia de leptospirosis humana y asociar dicha distribución con determinados factores ambientales, climatológicos y demográficos socioeconómicos mediante el uso de los Sistemas de Información Geográfica y modelos de regresión de Poisson. Se observó que los habitantes ubicados en lugares con alta precipitación promedio anual (1,882 -2,726 mm) tuvieron 65 % (IRR = 1.65; IC 95 %: 1.32, 2.08) exceso de riesgo de leptospirosis que aquellos que no se expusieron. Además, los datos sugirieron que los casos de leptospirosis se agruparon espacialmente mostrándose los puntos calientes al centro oeste de Puerto Rico.Palabras clave: leptospirosis, zoonosis, distribución espacial, sistemas de información geográfica, enfermedad infecciosa, precipitación SPATIAL AND EPIDEMIOLOGICAL ANALYSIS OF HUMAN LEPTOSPIROSIS IN PUERTO RICO, 1996 TO 2014 ABSTRACTAn ecological study was conducted with the confirmed cases of human leptospirosis reported to the Surveillance System of the Puerto Rico Department of Health between 1996 and 2014. The main purpose was to evaluate the spatial distribution of the occurrence of human leptospirosis and to associate this distribution with certain environmental and hydroclimatic factors through the use of Geographic Information Systems and Poisson regression models. It was observed that the population in census tracts with high annual average precipitation (1,882 -2,726 mm) had 65 % (IRR = 1.65, 95 % CI: 1.32, 2.08) of excess risk of leptospirosis than those who did not expose themselves. In addition, the data suggested that cases of leptospirosis were spatially clustered showing hot spots in the central west of Puerto Rico.

“…To do this, we have investigated the spatial distribution of S. mansoni using spatially structured and systematically recorded incidence data (chapter 3). The data was found to be valuable in detecting a spatial pattern of this highly focalized disease with dynamic distribution in time and space such as schistosomiasis (chapter 5), similarly to others water based diseases (Odoi et al, 2003;Osei & Duker, 2008;Vega-Corredor & Opadeyi, 2014). The study demonstrated that schistosomiasis was not distributed randomly and is significantly associated with wetlands and their use (agricultural).…”

“…Consequently, there is a clear need to explore the value of other sources of health data and alternative mapping approaches to complement prevalence inventories and support planning and implementation of S. mansoni control programs. For other water based diseases, incidence data from routine health statistics have been successfully used to complement prevalence studies and identify the spatial distribution of a given disease (Odoi et al, 2003;Osei & Duker, 2008;Vega-Corredor & Opadeyi, 2014). Given the availability of good quality spatially structured and systematically collected data at the health facility level, use of such incidence data seems feasible in Rwanda.…”

Leptospirosis is a disease usually acquired by humans through water contaminated with the urine of rodents that comes into direct contact with the cutaneous lesions, eyes, or mucous membranes. The disease has an important environmental component associated with climatic conditions and natural disasters, such as floods. We analyzed the relationship between rainfall and temperature and the incidence of leptospirosis in the top 30 municipalities with the highest numbers of cases of the disease in the period of 2007 to 2016. It was an ecological study of the time series of cases of leptospirosis, rainfall, and temperature with lags of 0, 1, 2, 3, and 4 weeks. A multilevel negative binomial regression model was implemented to evaluate the relationship between leptospirosis and both meteorological factors. In the 30 evaluated municipalities during the study period, a total of 5136 cases of leptospirosis were reported. According to the implemented statistical model, there was a positive association between the incidence of leptospirosis and rainfall with a lag of 1 week and a negative association with temperature with a lag of 4 weeks. Our results show the importance of short-term lags in rainfall and temperature for the occurrence of new cases of leptospirosis in Colombia.

Hydrology and public health: linking human leptospirosis and local hydrological dynamics in Trinidad, West Indies

Abstract: Background: Human leptospirosis is currently one of the most widespread bacterial zoonoses and is the only epidemic-prone infection that can be transmitted directly from contaminated water.
