The task was focused developing stratification based environmental (historical current), viral, social entomological situation >3,000 cities as part a system. platform, developed with open-source software pattern design, following European Agency standards...

Background Since 2009, Fundación Mundo Sano has implemented an Aedes aegypti Surveillance and Control Program in Tartagal city (Salta Province, Argentina). The purpose of this study was to analyze temporal dynamics Ae. breeding sites spatial distribution, during five years samplings, the effect control actions over vector population dynamics. Methodology/Principal Findings Seasonal entomological (larval) samplings were conducted 17,815 fixed urban area between 2009 2014. Based on information...

Fuel moisture content (FMC) is an important fuel property for assessing wildfire hazard, since it influences flammability and fire behavior. The relationship between FMC activity differs among land covers seems to be a of each ecosystem. Our objectives were analyze pre-fire different propose hazard classification the Sierras Chicas in Chaco Serrano subregion (Argentina), by analyzing distributions observed grasslands, shrublands forests using percentiles establish thresholds. For this...

Moisture content of live fuels (LFMC) is one the main factors determining fuel flammability and, therefore, a key indicator fire danger. In this study, we modeled relationship between spectral indices derived from satellite imagery and field estimations LFMC in Chaco Serrano subregion; then, analyzed danger based on calculations activity. Empirical models fitted for grasslands, forests, glossy privet forests may be considered very accurate R <sup...

ABSTRACT Background The impact of environmental factors on health is a key focus in public research. More studies are needed to explore how determinants influence birth outcomes. This study investigates the regional relationship between conditions and outcomes urban areas Argentina during 2018–2019. Methods Data from 657 localities were analyzed. Prevalence rates low weight (LBW), macrosomia, preterm births (PTB), small for gestational age (SGA) calculated using data Health Statistics...

Forecasting models were developed for predicting Aedes aegypti larval indices in an endemic area dengue (cities of Tartagal and Orán, northwestern Argentina), based on the Breteau House environmental variables considered with without time lags. Descriptive first each city index by multiple linear regressions, followed a regional model including both cities together. Finally, two forecasting (FRM) evaluated. FRM2 fit data significantly better than FRM1. An evaluation these showed higher...

Aedes aegypti is the main vector for Chikungunya, Dengue, and Zika viruses in Latin America it represents a threat our region. Taking into account this situation, several efforts have been done to use remote sensing support public health decision making. Moderate resolution imaging spectroradiometer (MODIS) sensor provides moderate-resolution products; therefore, we explore application of MODIS products vector-borne disease problems Argentina. We develop temporal forecasting models Ae....

The impact of control activities against Triatoma infestans (Klug) (Hemiptera: Reduviidae) in South America has a marked contrast within and outside the Gran Chaco region. Development geographic information system, as part an improvement program activities, allowed analysis spatial pattern house infestations by T. before after spraying with deltamethrin San Martin Department (an arid region central Argentina). overall peridomestic infestation index decreased from 48.2 to 28.2% insecticide...

Abstract The aim of this work was to explore the relationship between population density Akodon azarae (Muridae: Sigmodontinae) and climatic environmental variables, determine which them are associated within among‐year changes in rodent abundance agro‐ecosystems from south Córdoba, Argentina. study carried out a rural area central Argentina, 1983 2003. Density estimated as relative index (RDI). Temperature, precipitation humidity were obtained records National University Rio Cuarto....

The purpose of this paper is to analyze and interpret the onset some well‐characterized transient inertio‐gravity waves, observed during PYREX (Pyrénées Experiment) campaign. data used are high‐resolution soundings, launched every 6 hours on both sides ridge. In agreement with other observations made field campaign, certain among those soundings often show steady mountain waves. It appears that waves transients followed by propagating upward downward from level where initial large. To...

The application of remotely sensed data to public health has increased in Argentina the past few years, especially study vector-borne viral diseases such as dengue. normalized difference vegetation index (NDVI) been widely used for remote sensing well brightness temperature (BT) many years. Another environmental variable obtained from satellites is water (NDWI) status liquid space. aim present article was test effectiveness NDWI together with other satellite and meteorological develop two...

We use a Species Distribution Modeling (SDM) approach along with Geographic Information Systems (GIS) techniques to examine the potential distribution of hantavirus pulmonary syndrome (HPS) caused by Andes virus (ANDV) in southern Argentina and, more precisely, define and estimate area highest infection probability for humans, through combination map competent rodent host (Oligoryzomys longicaudatus). Sites confirmed cases HPS period 1995–2009 were mostly concentrated narrow strip (~90 km ×...

The main objective of this study was to obtain and analyse the space-time dynamics &lt;em&gt;Aedes aegypti&lt;/em&gt; breeding sites in Clorinda City, Formosa Province, Argentina coupled with landscape analysis using maximum entropy approach order generate a dengue vector niche model. In urban areas, without control activities, 12 entomologic (larval) samplings were performed during three years (October 2011 October 2014). surveillance area represented 16,511 houses. Predictive models for...

After elimination of the Aedes aegypti vector in South America 1960s, dengue outbreaks started to reoccur during 1990s; strongly Argentina since 1998. In 2016, Córdoba City had largest outbreak its history. this article we report including spatio-temporal analysis cases and vectors city. A total 653 were recorded by laboratory-based surveillance system georeferenced their residential addresses. Case maps generated from epidemiological week 1 (beginning January) 19 (mid-May). Dengue temporal...

The identification of Aedes aegypti breeding hotspots in urban areas is crucial for the rational design control strategies against this disease vector. Remote sensing and geographic information systems offer valuable tools mapping habitat suitability a given area. However, predicting species occurrences by means probability distribution maps based on transversal entomological surveys has limited utility local authorities. aim present study was to carefully examine temporal evolution number...

The COVID-19 outbreak measures of lockdown have generated exceptional urban behavior conditions allowing the analysis a unique scenario. We examined atmospheric emissions in Buenos Aires, Argentina, based on and industrial continuous monitoring NO2, PM10 PM2.5, NO2 (TROPOMI/Sentinel-5p) AOD (MAIAC/MODIS, Aqua) satellite products, addition with meteorological data. considered time intervals before after announcement lockdown, including same periods for 2019. results showed that concentrations...
