Estimates of the geographical distribution Culex mosquitoes in Americas have been limited to state and provincial levels United States Canada based on data from 1980s. Since these estimates were made, there many more documented observations new methods developed for species modeling. Moreover, mosquito distributions are affected by environmental conditions, which changed since This calls updated understand risk emerging re-emerging mosquito-borne diseases.We used contemporary data, drivers,...
Abstract Background The COVID-19 pandemic has caused more than 25 million cases and 800 thousand deaths worldwide to date. In early days of the pandemic, neither vaccines nor therapeutic drugs were available for this novel coronavirus. All measures prevent spread are thus based on reducing contact between infected susceptible individuals. Most these such as quarantine self-isolation require voluntary compliance by population. However, humans may act in their (perceived) self-interest only....
Abstract Background Vector-borne diseases (VBDs) are important contributors to the global burden of infectious due their epidemic potential, which can result in significant population and economic impacts. Oropouche fever, caused by virus (OROV), is an understudied zoonotic VBD febrile illness reported Central South America. The potential areas likely OROV spread remain unexplored, limiting capacities improve epidemiological surveillance. Methods To better understand capacity for OROV, we...
Abstract Emerging infectious diseases are increasingly understood as a hallmark of the Anthropocene 1–3 . Most experts agree that anthropogenic ecosystem change and high-risk contact among people, livestock, wildlife have contributed to recent emergence new zoonotic, vector-borne, environmentally-transmitted pathogens 1,4–6 However, extent which these factors also structure landscapes human infection outbreak risk is not well understood, beyond certain well-studied disease systems 7–9 Here,...
Abstract More than half of the world population is at risk vector-borne diseases including dengue fever, chikungunya, zika, yellow leishmaniasis, chagas disease, and malaria, with highest incidences in tropical regions. In Ecuador, are present from coastal Amazonian regions to Andes Mountains; however, a detailed characterization distribution their vectors has never been carried out. We estimate 14 above under present-day future climates. Our results consistently suggest that climate warming...
Large-scale biodiversity databases have become crucial information sources in many analyses biogeography, macroecology, and conservation biology, often involving development of empirical models species’ ecological niches predictions their geographic distributions. These analyses, however, can be impaired by the presence errors, particularly as regards taxonomic identifications accurate coordinates. Here, we present a detailed data-cleaning exercise based on two contrasting datasets; link...
Ecological niche modeling (ENM) and species distribution (SDM) are sets of tools that allow the estimation distributional areas on basis establishing relationships among known occurrences environmental variables. These have a wide range applications, particularly in biogeography, macroecology, conservation biology, granting prediction potential patterns present dynamics these different periods or scenarios. Due to their relevance practical usage methodologies has significantly increased...
Introduction: In Ecuador, poisonous snakebites are a public health problem. However, there is no recent hospital information from the Amazon. Objective: To retrospectively analyse clinical-epidemiological characteristics of in patients admitted to Ecuadorian Materials and methods: This cross-sectional study conducted at Nueva Loja-Sucumbíos Provincial Hospital, bordering Colombia (2017-2021). Demographic, epidemiological clinical variables, condition discharge, were obtained file Ministerio...
Bacillus cereus biovar anthracis (Bcbva) is an emergent bacterium closely related to anthracis, the etiological agent of anthrax. The latter has a worldwide distribution and usually causes infectious disease in mammals associated with savanna ecosystems. Bcbva was identified humid tropical forests Côte d'Ivoire 2001. Here, we characterize potential geographic distributions West Africa B. sub-Saharan using ecological niche modeling approach.Georeferenced occurrence data for were obtained from...
Oropouche virus causes fever, an arboviral disease transmitted mainly by midges of the genus Culicoides and Culex mosquitoes. Clinical presentation fever in humans includes headache, rash, myalgia, rare cases spontaneous bleeding aseptic meningitis. Landscape change has been proposed as a driver emergence.To investigate landscape epidemiology outbreak that began April 2016 Cusco, Peru.We used information vegetation multivariate spatial analyses including ecological niche modeling. Vegetation...
Starry stonewort (Nitellopsis obtusa) is an alga that has emerged as aquatic invasive species of concern in the United States. Where established, starry can interfere with recreational uses water bodies and potentially have ecological impacts. Incipient invasion Minnesota provides opportunity to predict future expansion order target early detection strategic management. We used niche models identify suitable areas for based on global occurrence records present-day climate conditions....
Ticks of the Amblyomma cajennense species complex are important vectors spotted fever in Latin America. Environmental conditions determine geographic distribution ticks, such that climate change could influence tick-borne diseases. This study aimed to analyze potential A. ticks a Brazil region under present-day and future models, assuming dispersal limitations non-evolutionary adaptation these tick populations warming. Records sensu stricto (s.s.) sculptum were analyzed. Niche models...
A countrywide epidemiological study was performed to elucidate the current geographic distribution of causative species cutaneous leishmaniasis (CL) in Ecuador by using FTA card-spotted samples and smear slides as DNA sources. Putative Leishmania 165 collected from patients with CL 16 provinces were examined at level based on cytochrome b gene sequence analysis. Of these, 125 successfully identified (Viannia) guyanensis, L. (V.) braziliensis, naiffi, lainsoni, (Leishmania) mexicana. Two...
Abstract Middle Paleolithic Neanderthal populations occupied Eurasia for at least 250,000 years prior to the arrival of anatomically modern humans. While a considerable body archaeological research has focused on material culture and subsistence strategies, little attention been paid relationship between regionally specific cultural trajectories their associated existing fundamental ecological niches, nor how latter varied across periods climatic variability. We examine record naturally...
Background In Ecuador, leptospirosis surveillance involves a mandatory notification of all cases and hospitalization for severe illness. Morbidity mortality are, nevertheless, underestimated contribute directly to the status as neglected disease. Leptospira spp. is zoonotic in Ecuador with established endemic transmission Tropics. Here, we review retrospective national data within country aid control strategies. Methodology/Principal findings population-based nationwide study, analysed...
For much of the twentieth century, many or most scholarly journals in biodiversity, ecology, biogeography and conservation were owned published by scientific societies made available to broader community at relatively low cost. However, past several decades have seen a dominant process commercialization publication this field, either commercial publishing firms taking over society (e.g., Evolution), publishers starting new fill "niches" that until then empty ecosystem. Diversity...
Hantavirus pulmonary syndrome (HPS) is an infection endemic in Chile and Argentina, caused by Andes hantavirus (ANDV). The rodent Oligoryzomys longicaudatus suggested as the main reservoir, although several other species of Sigmodontinae are known hosts ANDV. Here, we explore potential ANDV transmission risk to humans southern South America, based on eco-epidemiological associations among: six host species, seropositive rodents, human HPS cases. We used ecological niche modeling...
Abstract Primary health care is at the core of systems that aim to ensure equitable outcomes. With an estimated 36% rural population, Ecuador has a service year programme (created in 1970) for recently graduated doctors provide primary services and remote communities. However, little been done monitor or evaluate since its inception. The this study was assess Ecuador’s medical implementation with focus on distribution across country. For purpose, we analysed all doctors, including...
