Critical fluctuations in epidemic models explain COVID‑19 post‑lockdown dynamics
Aguiar, M.; BidaurrazagaVan‑Dierdonc, J.; Mar, J.; Cusimano, N.; Knopoff, D.A.; Anam, V.; Stollenwerk, N. (2021-07-06)
As the COVID-19 pandemic progressed, research on mathematical modeling became imperative and very influential to understand the epidemiological dynamics of disease spreading. The momentary reproduction ratio r(t) of an ... -

In December 2019, a severe respiratory syndrome (COVID-19) caused by a new coronavirus (SARS-CoV-2) was identified in China and spread rapidly around the globe. COVID-19 was declared a pandemic by the World Health Organization ... -
Effect of General Cross-Immunity Protection and Antibody- Dependent Enhancement in Dengue Dynamics
Steindorf, V; Oliva, S.; Wu, J.; Aguiar, M. (2022-02-13)
A mathematical model to describe the dynamic of a multiserotype infectious disease at the population level is studied. Applied to dengue fever epidemiology, we analyse a mathematical model with time delay to describe the ... -
Ethics of a partially effective dengue vaccine: Lessons from the Philippines

Dengvaxia, a chimeric yellow fever tetravalent dengue vaccine developed by SanofiPasteur is widely licensed in dengue-endemic countries. In a large cohort study Dengvaxia was found to partially protect children who had ... -
The Impact of Serotype Cross-Protection on Vaccine Trials: DENVax as a Case Study
Aguiar, M.; Stollenwerk, N. (2020-11)
There is a growing public health need for effective preventive interventions against dengue, and a safe, effective and affordable dengue vaccine against the four serotypes would be a significant achievement for disease ... -
Mathematical models for dengue fever epidemiology: a 10-year systematic review
Aguiar, M.; Anam, V.; Blyuss, K.; Estadilla, C. D. S.; Guerrero, B.; Knopoff, D.A.; Kooi, B. W.; Srivastav, A. K.; Steindorf, V.; Stollenwerk, N. (2022-02-15)
Mathematical models have a long history in epidemiological research, and as the COVID-19 pandemic progressed, research on mathematical modeling became imperative and very influential to understand the epidemiological ... -
Modeling COVID-19: Challenges and results
Aguiar, M. (2020-10)
Weird times we are living in. While lots of technological, medical and scientific advances are generated in a short period of time, we are now fighting a pandemic, trying to stop the spread of a new virus that has not only ... -
Modeling dengue immune responses mediated by antibodies: A qualitative study
Sebayang, A.A.; Fahlena, H.; Anam, V.; Knopoff, D.A.; Stollenwerk, N.; Aguiar, M.; Soewono, E. (2021-09-01)
Dengue fever is a viral mosquito-borne infection and a major international public health concern. With 2.5 billion people at risk of acquiring the infection around the world, disease severity is influenced by the immunological ... -
Modeling Dengue Immune Responses Mediated by Antibodies: Insights on the Biological Parameters to Describe Dengue Infections
Anam, V.; Sebayang, A.A.; Fahlena, H.; Knopoff, D.A.; Stollenwerk, N.; Soewono, E.; Aguiar, M. (2022-03-18)
Dengue fever is a viral mosquito-borne disease, a significant global health concern, with more than one third of the world population at risk of acquiring the disease. Caused by 4 antigenically distinct but related virus ... -
Modelling COVID 19 in the Basque Country from introduction to control measure response
Aguiar, M.; Ortuondo, E.M.; Bidaurrazaga Van-Dierdonck, J.; Mar J; Stollenwerk, N. (2020-10)
In March 2020, a multidisciplinary task force (so‐called Basque Modelling Task Force, BMTF) was created to assist the Basque health managers and Government during the COVID‐19 responses. BMTF is a modelling team, working ... -
Modelling Holling type II functional response in deterministic and stochastic food chain models with mass conservation
Stollenwerk, N.; Aguiar, M.; Kooi, B. W. (2022-03-01)
The Rosenzweig-MacArthur predator-prey model is the building block in modeling food chain, food webs and ecosystems. There are a number of hidden assumptions involved in the derivation. For instance the prey population ... -
A multiscale network-based model of contagion dynamics: heterogeneity, spatial distancing and vaccination
Aguiar, M.; Dosi, G.; Knopoff, D.A.; Virgillito, M.E. (2021)
Lockdown and vaccination policies have been the major concern in the last year in order to contain the SARS-CoV-2 infection during the COVID-19 pandemic. In this paper we present a model able to evaluate alternative lockdown ... -
Reproduction ratio and growth rates: Measures for an unfolding pandemic
Aguiar, M.; Bidaurrazaga Van-Dierdonck, J.; Stollenwerk, N. (2020-05)
The initial exponential growth rate of an epidemic is an important measure that follows directly from data at hand, commonly used to infer the basic reproduction number. As the growth rates λ(t) of tested positive COVID-19 ... -
The role of mild and asymptomatic infections on COVID-19 vaccines performance: A modeling study
Aguiar, M.; Bidaurrazaga Van-Dierdonck, J.; Mar, J; Stollenwerk, N. (2021-11-16)
