Brazil is a tropical country that largely covered by rainforests and other natural ecosystems, which provide ideal conditions for the existence of many arboviruses. However, few analyses have examined associations between environmental factors arboviral diseases. Thus, based on hypothesis correlation environment epidemiology, proposals this study were (1) to obtain probability occurrence Oropouche, Mayaro, Saint Louis Rocio fevers in corresponding periods outbreaks; (2) describe...

Brazil experiences a large number of visceral leishmaniasis (VL) cases. Our objective was to examine both spatial patterns dispersion and space-time trends for this disease.We used all autochthonous confirmed cases VL in from 2001 2017.Throughout Brazil, 53,715 human were recorded. The Northeast, Southeast, Midwest regions the most affected areas presented higher risk transmission. Regarding spatiotemporal variation, significant differences observed each year, with peak 2005.The dynamics...

Dengue is a mosquito-borne febrile disease infecting millions of people worldwide. Identification high-risk areas will allow public health services to concentrate their efforts in where outbreaks are most likely occur. The present study focuses on describing the spatiotemporal evolution dengue Brazil from 2000 2018.To assess pattern behaviour and trend outbreaks, non-parametric kernel estimator method Mann-Kendall test, respectively, were used. Bivariate global Moran's I statistic was used...

In 1909, Arthur Neiva published an article titled “Contribuição para os estudos dos dipteros. Observação sobre a biolojia e sistematica das anofelinas brasileiras suas relações com o impaludismo”, highlighting the biology, ecology, and distribution of Anophelinae mosquitoes need for more taxonomic studies in Brazil. This came 11 years after Ronald Ross Grassi demonstrated mosquito roles transmitting Plasmodium to birds humans. Despite considerable advances understanding species, knowledge...

Scorpion envenomation is a significant public health concern in São Paulo, Brazil, and its incidence mortality have increased recent decades. The present study analyzed documented scorpion notifications from 2008 to 2018 throughout the 645 municipalities of Paulo. Annual rates were calculated stratified according sex age. local empirical Bayesian method Getis-Ord Gi* statistic used represent standardized identify high- low-risk agglomerates. rate quintupled between 2018. Overall, risk was...

Abstract Background West Nile virus (WNV) is a vector-borne pathogen of global relevance and currently the most widely distributed flavivirus causing encephalitis worldwide. Climate conditions have direct indirect impacts on vector abundance dynamics within mosquito. The significance environmental variables as drivers in WNV epidemiology increasing under current climate change scenario. In this study we used machine learning algorithm to model distributions South America. Methods Our...

We addressed the potential associations among temporal and spatial distribution of larval habitats Aedes (Stegomyia) aegypti, presence urban heat islands socioeconomic factors. Data on were collected in Santa Bárbara d’Oeste, São Paulo, Brazil, from 2004 to 2006, variations analysed using a wavelet-based approach. quantified by calculating surface temperatures results wavelet analyses grey level transformation Thematic Mapper images (Landsat 5). Ae. aegypti geo-referenced corresponding test...

The analysis of the influence edaphic finer textures, as a facilitating factor for expansion forest formations in absence fire, was possible thanks to rare characteristics found savanna fragment located State São Paulo, Brazil. total suppression fire over four decades, and occurrence two physiognomies, cerrado sensu stricto cerradão, allowed conduction this study based on hypothesis that physiognomy aspect consisting fire-sensitive tree shrubs species, is favored by higher soil hydric...

Background Seasonal fluctuations in weather are recognized as factors that affect both Aedes ( Ae .) aegypti mosquitoes and the diseases they carry, such dengue fever. The El Niño-Southern Oscillation (ENSO) is widely regarded one of most impactful atmospheric phenomena on Earth, characterized by interplay shifting ocean temperatures, trade wind intensity, pressure, resulting extensive alterations climate conditions. In this study, we investigate influence ENSO local conditions...

Abstract Background Dengue is an arbovirus disease that threatens approximately 200 million people annually worldwide. Aedes ( Stegomyia ) aegypti (Linnaeus, 1762) anthropophilic mosquito, extremely well adapted to the urban environment and utilizes varied habitats for egg-laying development. This study analysed distribution of mosquito larvae eggs in area Santa Bárbara dʼOeste, São Paulo, Brazil. The spatial correlation between locations which store recyclable materials were verified....

Scorpion stings in Brazil represent a major public health problem due to their incidence and potential ability lead severe often fatal clinical outcomes. A better understanding of scorpionism determinants is essential for precise comprehension accident dynamics guide policy. Our study the first model spatio-temporal variability across municipalities São Paulo (SP) investigate its relationship with demographic, socioeconomic, environmental, climatic variables.

Spatial evaluation of Culicidae (Diptera) larvae from different breeding sites: application a geospatial method and implications for vector control. This study investigates the spatial distribution urban informs entomological monitoring species that use artificial containers as larval habitats. Collections mosquito were conducted in São Paulo State municipality Santa Bárbara d' Oeste between 2004 2006 during house-to-house visits. A total 1,891 samples nine sampled. Species was assessed...

The control of dengue constitutes a great challenge for public health; however, the methods normally used have shown themselves to be insufficient keep indices infestation Aedes aegypti under control. Recently, beyond large number cases and deaths associated with dengue, new risks arisen such as those represented by chikungunya fever Zika. In light significance these problems within health context, two areas in municipality interior State São Paulo, Brazil were selected 2014. One them,...

A visão integrada dos problemas sociais através das variáveis sócio-econômicas e políticas conduzem a estudos multidisciplinares que buscam compreender propor soluções à complexidade crescente estudados. Porém, na maioria desta natureza, o tratamento dados é efetuado de forma tradicional. Atualmente, esta perspectiva está sendo gradualmente substituída por modernas técnicas análise espacial, contidas nos sistemas informação geográfica, possibilitam integração manipulação um grande volume...

As queimaduras causadas pelo contato com lagartas do gênero Lonomia, foi descrita pela primeira no Brasil em 1986. A partir de 1989, estes acidentes assumem dimensões epidêmicas nos Estados Santa Catariana e Rio Grande Sul. Nos últimos anos, nota-se o aumento dos casos, verificando-se a tendência expansão para outras áreas país. Assim, objetivo deste trabalho é efetuar mapeamento provocados lagarta Brasil, período 2000 2007, utilizando sistemas informação geográfica. Os resultados mostram...

In view of the adaptive ability mosquitoes and their role in transport infective agents, entomological surveys undertaken transitional environments are very important for determination risk they represent Public Health. Among principal vectors infectious agents involved occurrence arboviruses, such as dengue, example, Culicidae-insects capable installing themselves urban nuclei, which exist within areas containing vestigial forests. This present study conducted a survey mosquito species by...

Abstract Leptospirosis is an epidemic disease caused by bacteria of the Leptospira genus. Its risk closely associated with inadequate sanitation and flooding, a common public health challenge in large urban centers together environmental modifications, socio-economic factors. This retrospective observational research investigated association between three contextual factors (drainage, soil impermeability social vulnerability) distribution leptospirosis cases Campinas city, São Paulo, Brazil....
