Stochastic two-patch epidemic model with nonlinear recidivism
Juan G. Calvo, Mario I. Simoy, Juan P. Aparicio +2
We develop a stochastic two-patch epidemic model with nonlinear recidivism to investigate infectious disease dynamics in heterogeneous populations. Extending a deterministic framew…
Robust domain decomposition methods for high-contrast multiscale problems on irregular domains with virtual element discretizations
Juan G. Calvo, Juan Galvis
Our research focuses on the development of domain decomposition preconditioners tailored for second-order elliptic partial differential equations. Our approach addresses two major…
Bayesian spatio-temporal model with INLA for dengue fever risk prediction in Costa Rica
Shu-Wei Chou-Chen, Luis A. Barboza, Paola Vásquez +4
Due to the rapid geographic spread of the Aedes mosquito and the increase in dengue incidence, dengue fever has been an increasing concern for public health authorities in tropical…
A nonlinear relapse model with disaggregated contact rates: analysis of a forward-backward bifurcation
Jimmy Calvo-Monge, Fabio Sanchez, Juan G. Calvo +1
We developed a nonlinear differential equation model to explore the dynamics of relapse phenomena. Our incidence rate function is formulated, taking inspiration from recent adaptiv…
Common patterns between dengue cases, climate, and local environmental variables in Costa Rica: A Wavelet Approach
Yury E. Garcia, Shu-Wei Chou-Chen, Luis A. Barboza +6
Throughout history, prevention and control of dengue transmission have challenged public health authorities worldwide. In the last decades, the interaction of multiple factors, suc…
A mathematical model with nonlinear relapse: conditions for a forward-backward bifurcation
Fabio Sanchez, Jorge Arroyo-Esquivel, Juan Gabriel Calvo
We constructed a Susceptible-Addicted-Reformed model and explored the dynamics of nonlinear relapse in the Reformed population. The transition from susceptible considered {\it at-r…
Assessing dengue fever risk in Costa Rica by using climate variables and machine learning techniques
Luis A. Barboza, Shu-Wei Chou, Paola Vásquez +4
Dengue fever is a vector-borne disease mostly endemic to tropical and subtropical countries that affect millions every year and is considered a significant burden for public health…
Projecting the Impact of Covid-19 Variants and Vaccination Strategies in Disease Transmission using a Multilayer Network Model in Costa Rica
Yury E. García, Gustavo Mery, Paola Vásquez +4
For countries starting to receive steady supplies of vaccines against SARS-CoV-2, the course of Covid-19 for the following months will be determined by the emergence of new variant…
A multilayer network model of Covid-19: implications in public health policy in Costa Rica
Fabio Sanchez, Juan G. Calvo, Gustavo Mery +5
Successful partnerships between researchers, experts and public health authorities has been critical to navigate the challenges of the Covid-19 pandemic worldwide. In Costa Rica, w…
Wavelet Analysis of Dengue Incidence and its Correlation with Weather and Vegetation Variables in Costa Rica
Yury E. García, Luis A. Barboza, Fabio Sanchez +2
Dengue represents a serious public health problem in tropical and subtropical regions worldwide. The number of dengue cases and its geographical expansion has increased in recent d…
A Multilayer Network Model implementation for Covid-19
Juan G. Calvo, Fabio Sanchez, Luis A. Barboza +2
We present a numerical implementation for a multilayer network used to model the transmission of Covid-19 or other diseases with a similar transmission mechanism. The model incorpo…
The role of mobility and sanitary measures on Covid-19 in Costa Rica, March through July 2020
Luis A. Barboza, Paola Vásquez, Gustavo Mery +5
The aim of this paper is to infer the effects that changes on human mobility had on the transmission dynamics during the first four months of the SARS-CoV-2 outbreak in Costa Rica,…
Dengue model with early-life stage of vectors and age-structure within host
Fabio Sanchez, Juan G. Calvo
We construct an epidemic model for the transmission of dengue fever with an early-life stage in the vector dynamics and age-structure within hosts. The early-life stage of the vect…
A two-patch epidemic model with nonlinear reinfection
Juan G. Calvo, Alberto Hernández, Mason A. Porter +1
The propagation of infectious diseases and its impact on individuals play a major role in disease dynamics, and it is important to incorporate population heterogeneity into efforts…
The role of short-term immigration on disease dynamics: An SIR model with age-structure
Fabio Sanchez, Juan Gabriel Calvo
We formulate an age-structured nonlinear partial differential equation model that features short-term immigration effects in a population. Individuals can immigrate into the popula…
A Partial Differential Equation Model with Age-Structure and Nonlinear Recidivism: Conditions for a Backward Bifurcation and a General Numerical Implementation
Fabio Sanchez, Juan G. Calvo, Esteban Segura +1
\noindent We formulate an age-structured three-staged nonlinear partial differential equation model that features {\it nonlinear} recidivism to the infected ({\it infectious}) clas…
