An educational intervention on the risk perception of pesticides exposure and organophosphate metabolites urinary concentrations in rural school children in Maule Region, Chile
Muñoz-Quezada, María Teresa; Lucero-Mondaca, Boris; Bradman, Asa; Steenland, Kyle; Zúñiga-Venegas, Liliana A.; Calafat, Antonia M.; Ospina, Maria; Iglesias, Verónica; Muñoz, María Pía; Buralli, Rafael J.; Fredes-Monsalve, Claudio; Gutiérrez-Jara, Juan P. (2019)Background: Organophosphate (OP) pesticides can be hazardous to human health if not applied with appropriate precautions. There is evidence in the Maule region of Chile that rural schoolchildren are exposed to OP ...

An index to quantify individual social responsibility in the decision to be vaccinated
In the context of generic infectious disease studies, the aim of this paper is to quantify and represent the individual social responsibility based on whether or not a single individual is vaccinated. Although the objective ...

An SIR-type epidemiological model that integrates social distancing as a dynamic law based on point prevalence and socio-behavioral factors
Cabrera-Hernández, Maritza; Cordova-Lepe, Fernando ; Gutiérrez-Jara, Juan P.; Vogt-Geisse, Katia (2021)Modeling human behavior within mathematical models of infectious diseases is a key component to understand and control disease spread. We present a mathematical compartmental model of Susceptible–Infectious–Removed to ...

Collateral effects of insecticide-treated nets on human and environmental safety in an epidemiological model for malaria with human risk perception
Gutiérrez-Jara, Juan P.; Vogt-Geisse, Katia; Cabrera, Maritza Guadalupe (2022)Malaria remains a major health problem in many parts of the world, including Sub-Saharan Africa. Insecticide-treated nets, in combination with other control measures, have been effective in reducing malaria incidence over ...

Dynamics between infectious diseases with two susceptibility conditions: a mathematical model
Gutiérrez-Jara, Juan P.; Córdova-Lepe, Fernando; Muñoz-Quezada, María Teresa (2019)This paper presents a novel epidemiological transmission model of a population affected by two different susceptible-infected-susceptible infectious diseases. For each disease, individuals fall into one of the two ...

Efects of human mobility and behavior on disease transmission in a COVID‑19 mathematical model
Gutiérrez-Jara, Juan P.; Vogt-Geisse, Katia; Cabrera, Maritza; Córdova-Lepe, Fernando; Muñoz-Quezada, María Teresa (2022)Human interactions and perceptions about health risk are essential to understand the evolution over the course of a pandemic. We present a Susceptible-Exposed-Asymptomatic-Infectious-Recovered-Susceptible mathematical model ...

Health effects of pesticide exposure in latin american and the caribbean populations: a scoping review
Zúñiga-Venegas, Liliana A.; Hyland, Carly; Muñoz-Quezada, María Teresa; Quiros-Alcala, Lesliam; Butinof, Mariana; Junqueira Buralli, Rafael; Cardenas, Andres; Fernández, Ricardo Antonio; Foerster, Claudia; Gouveia, Nelson; Gutiérrez-Jara, Juan P.; Lucero-Mondaca, Boris; Muñoz, María Pía; Ramirez, Muriel; Smith, Anna R; Tirado, Noemi; Wendel de Joode, Berna van; Calaf, Gloria M; Handal, Alexis J; Soares da Silva, Agnes; Cortés, Sandra; Mora, Ana Maria (2022)Background: Multiple epidemiological studies have shown that exposure to pesticides is associated with adverse health outcomes. However, the literature on pesticide-related health effects in the Latin American and the ...

Longitudinal exposure to pyrethroids (3-PBA and trans-DCCA) and 2,4-D herbicide in rural schoolchildren of Maule region, Chile
Muñoz-Quezada, María Teresa; Lucero-Mondaca, Boris; Gutiérrez-Jara, Juan P.; Buralli, Rafael J.; Zúñiga-Venegas, Liliana A.; Muñoz, María Pía; Vilches-Ponce, Karina; Iglesias, Verónica (2020)Background: Several studies showed that early exposure to pesticides affects the development and health of children. In Maule, there is previous evidence of the high exposure to organophosphate pesticides (OP) of schoolchildren. ...

Mathematical approach to the prevention-immigration causality of outbreaks of sexually transmitted diseases in Chile using HIV as a model
Cordova-Lepe, Fernando ; Cabrera-Hernández, Maritza; Gutiérrez-Jara, Juan P.; Gutiérrez, Rodrigo I. (2019)In Chile, in the contingent public debate about the alarming indicators of the prevalence of infectious diseases (such sexually transmitted ones), two factors stand out as determinants: inefficient or scarce preventive ...

Modelización del impacto epidemiológico de la existencia de un grupo conductual preventivo
En lo que concierne a salud, la experiencia indica que en toda población humana existe un porcentaje de individuos que se comporta en forma consciente ante la presencia de enfermedades infectocontagiosas. Esto implica que ...

Modelo de umbral de reducción de tasa diaria de casos COVID-19 para evitar el colapso hospitalario en Chile
Gutiérrez Aguilar, Rodrigo; Cordova-Lepe, Fernando ; Muñoz-Quezada, María Teresa; Gutiérrez-Jara, Juan P. (2020)Mediante un modelo matemático este trabajo explora la problemática de la disponibilidad versus sobredemanda de procesos críticos hospitalarias (por ejemplo, camas críticas) ante una fuerte expansión epidémica como la que ...

Number of COVID-19 cases in Chile at 120 days with data at 21/03/2020 and threshold of daily effort to flatten the epi-curve
Realizamos una prospectiva básica, con datos al 21/03/2020 de la evolución del número de casos COVID-19 diarios en Chile con datos del Ministerio de Salud. Asumiendo un crecimiento aritmético en la segunda variación de los ...

Pesticide application, educational treatment and infectious respiratory diseases. A mechanistic model with two impulsive controls
In this paper, we develop and analyze an SIS-type epidemiological-mathematical model of the interaction between pesticide use and infectious respiratory disease transmission for investigating the impact of pesticide ...

Susceptibility to organophosphates pesticides and the development of infectious-contagious respiratory diseases
In this paper we develop an SIRS compartmental model to investigate the dynamic interplay between pesticide intoxication and the spread of infectious-contagious respiratory diseases. We are particularly interested in ...
