The basic reproduction number R0 and effectiveness of reactive interventions during dengue epidemics: the 2002 dengue outbreak in Easter Island, Chile.
(American Institute of Mathematical Sciences, 2013)
We use a stochastic simulation model to explore the effect of reactive intervention strategies during the 2002 dengue outbreak in the small population of Easter Island, Chile. We quantified the effect of interventions on ...
A comparative analysis of the relative efficacy of vector-control strategies against dengue fever
(SpringerNova York, 2014-03-12)
Dengue is considered one of the most important vector-borne infection, affecting almost half of the world population with 50 to 100 million cases every year. In this paper, we present one of the simplest models that can ...
Dinâmica de um sistema presa-predador com predador infectado por uma doença
(Universidade Federal de Santa MariaBRMatemáticaUFSMPrograma de Pós-Graduação em Matemática, 2013-05-10)
The aim of this work is to study the temporal and spatiotemporal evolution of a threedimensional
system that describes a predator-prey dynamics, where the predator population
can develop an infectious disease.
Thus, the ...
Morphology, reproduction and karyology in the rare Andean Poa gymnantha
(International Association for Plant Taxonomy, 2008-02)
We report agamic reproduction in Poa gymnantha, an endemic species from the high Andes of Peru, Bolivia and Chile, known only from pistillate plants. This is the first description of apomixis in Poa from South America. The ...
A MATHEMATICAL ANALYSIS of ZIKA VIRUS EPIDEMIC in RIO de JANEIRO AS A VECTOR-BORNE and SEXUALLY TRANSMITTED DISEASE
(2019-03-01)
In this work we formulate a mathematical model to assess the importance of sexual transmission during the Zika virus outbreak that occurred in Rio de Janeiro, Brazil, in 2015. To this end, we deduce from the model an ...
Assessing the Impact of Prophylactic Vaccines on HPV Prevalence
(Sociedade Brasileira de Matemática Aplicada e Computacional, 2019-09-16)
A mathematical model considering female and male individuals is proposed to evaluate vaccination strategies applied to control of HPV transmission in human population. The basic reproductive number of the disease, R 0 is ...
Coronavirus pandemic: A predictive analysis of the peak outbreak epidemic in South Africa, Turkey, and Brazil
In this research, we are interested in predicting the epidemic peak outbreak of the Coronavirus in South
Africa, Turkey, and Brazil. Until now, there is no known safe treatment, hence the immunity system of the
individual ...
Vector borne diseases on an urban environment: the effects of heterogeneity and human circulation
(Elsevier Science Bv, 2017-06)
We study the effect of human circulation and host/vector heterogeneities on the onset of epidemics of arboviruses. From a meta-population dynamics based on the classical Bailey-Dietz model, we derive a multi-group model ...
Landscape Diversity Influences Dispersal and Establishment of Pest with Complex Nutritional Ecology
(Springer, 2014-07-01)
We studied the effects of landscape structure on species with resource nutritional partition between the immature and adult stages by investigating how food quality and spatial structure of a landscape may affect the ...
