“…Our data additionally show that disease morbidity has increased during the last decade. This is possibly due to two reasons: in 2010 an active search for patients with dengue was established after several environmental contingencies had occurred (in this period there were a total of 33 tropical cyclones and two hurricanes Agatha and Igor) in the coastal areas of the Pacific and the Atlantic [ 58 , 59 ]. The second reason for the heightened number of cases is possibly due to the fact that 17 state laboratories were established (certified for the diagnosis of leptospirosis) and assigned to the National Network of Public Health Laboratories [ 60 ], which increased the number of analysed samples.…”

BackgroundLeptospirosis is widespread in Mexico, yet the potential distribution and risk of the disease remain unknown.Methodology/Principal FindingsWe analysed morbidity and mortality according to age and gender based on three sources of data reported by the Ministry of Health and the National Institute of Geography and Statics of Mexico, for the decade 2000–2010. A total of 1,547 cases were reported in 27 states, the majority of which were registered during the rainy season, and the most affected age group was 25–44 years old. Although leptospirosis has been reported as an occupational disease of males, analysis of morbidity in Mexico showed no male preference. A total number of 198 deaths were registered in 21 states, mainly in urban settings. Mortality was higher in males (61.1%) as compared to females (38.9%), and the case fatality ratio was also increased in males. The overall case fatality ratio in Mexico was elevated (12.8%), as compared to other countries. We additionally determined the potential disease distribution by examining the spatial epidemiology combined with spatial modeling using ecological niche modeling techniques. We identified regions where leptospirosis could be present and created a potential distribution map using bioclimatic variables derived from temperature and precipitation. Our data show that the distribution of the cases was more related to temperature (75%) than to precipitation variables. Ecological niche modeling showed predictive areas that were widely distributed in central and southern Mexico, excluding areas characterized by extreme climates.Conclusions/SignificanceIn conclusion, an epidemiological surveillance of leptospirosis is recommended in Mexico, since 55.7% of the country has environmental conditions fulfilling the criteria that favor the presence of the disease.

Urbanisation has modified the distribution and community composition of mosquito species (Culicidae). Habitat disturbance may increase the risk of loss of species diversity and the occurrence of vector-borne diseases. Studies on the presence of larvae and the eco-physicochemical characteristics of water bodies near urban areas provide information on the risk of these diseases. In this study, the presence of larvae in different types of urban and periurban water bodies in Villahermosa City, Tabasco, Mexico was analysed. The eco-physicochemical characteristics of each collecting site were measured. A total of 67 528 larvae were collected, 1366 were identified to species, and 15 species were observed. Although Culex spp. were the most dominant species, Anopheles albimanus was the only species present in all habitats. Despite the large variability in the parameters measured (especially in physicochemical parameters; e.g., pH, electrical conductivity, total dissolved solids), differences were observed among the breeding sites. Weak correlations were found between eco-physicochemical parameters and species presence. Predators may have a major role in determining community processes in the region. Habitat disturbance may be responsible for eco-physicochemical variations altering mosquito community composition, resulting in the loss of endemic mosquito species and increasing the risk of vector-borne diseases in Villahermosa.

“…Antes de estos sucesos y a lo largo de su historia, México se ha caracterizado por ser un país vulnerable a diversos fenómenos hidro-meteorológicos y geofísicos, debido a su ubicación geográfica (2), principalmente la formación de ciclones tropicales en la costa del Pacífico y del Golfo de México (3,4), además de los que se asocian con la inestabilidad de los suelos (5-7). Respecto a la incidencia de desastres en México, Naciones Unidas ha expresado que se encuentra entre los 30 países con mayor exposición a desastres, tres o más, de múltiples magnitudes al año (8).…”

RESUMEN Objetivo Caracterizar los patrones de ocurrencia de desastres, defunciones, población afectada y daños económicos en México en el período 1900-2016. Métodos Se realizó un estudio descriptivo de las frecuencias de desastres, de defunciones y de personas afectadas y se estimaron los daños económicos para México en el período señalado. Se utilizó la base de datos EM-DAT del International Disaster Database, del Centre de Recherche sur l'Epidémiologie des Désastres de L'École de Santé Publique de l'Université Catholique de Louvain, Belgique. Resultados Se observó un aumento de la frecuencia de desastres a partir de la década de los noventa. Los patrones de ocurrencia de desastres en México indican que el porcentaje más alto es el de los de origen meteorológico e hidrológico (tormentas, temperaturas extremas, inundaciones, aludes y acción de los oleajes), que representan la mitad de los desastres registrados. El pocentaje de los desastres de origen meteorológico, hidrológico y climatológico oscila entre 50%-60% y son los que han provocado mayores daños a México en la serie analizada. Los que más defunciones han causado son los geofísicos, seguidos de los hidrológicos y los meteorológicos. El costo de los daños asciende con el paso de las décadas. Conclusiones De los 219 desastres analizados en el período mencionado, 63,4% se ha registrado a partir de 1990. La frecuencia de los desastres y las necesidades de inversión en su prevnción y mitigación van en aumento.
