Efficient numerical computation of the basic reproduction number for structured populations [PDF]

open access: yesJournal of Computational and Applied Mathematics, 2020
As widely known, the basic reproduction number plays a key role in weighing birth/infection and death/recovery processes in several models of population dynamics. In this general setting, its characterization as the spectral radius of next generation operators is rather elegant, but simultaneously poses serious obstacles to its practical determination.

A network immuno-epidemiological model of HIV and opioid epidemics

open access: yesMathematical Biosciences and Engineering, 2023
In this paper, we introduce a novel multi-scale network model of two epidemics: HIV infection and opioid addiction. The HIV infection dynamics is modeled on a complex network. We determine the basic reproduction number of HIV infection, $ \mathcal{R}_{v}

Estimation of the basic reproduction number, average incubation time, asymptomatic infection rate, and case fatality rate for COVID‐19: Meta‐analysis and sensitivity analysis

open access: yesmedRxiv, 2020
The coronavirus disease‐2019 (COVID‐19) has been found to be caused by the severe acute respiratory syndrome coronavirus 2 (SARS‐CoV‐2). However, comprehensive knowledge of COVID‐19 remains incomplete and many important features are still unknown.

Bacteria–bacteriophage cycles facilitate Cholera outbreak cycles: an indirect Susceptible-Infected-Recovered-Bacteria- Phage (iSIRBP) model-based mathematical study

open access: yesJournal of Biological Dynamics, 2022
Cholera is an acute enteric infectious disease caused by the Gram-negative bacterium Vibrio cholerae. Despite a huge body of research, the precise nature of its transmission dynamics has yet to be fully elucidated.

Global dynamics of a periodic SEIRS model with general incidence rate [PDF]

open access: yes, 2017
We consider a family of periodic SEIRS epidemic models with a fairly general incidence rate and it is shown the basic reproduction number determines the global dynamics of the models and it is a threshold parameter for persistence.

REPRODUCTION AND HABITAT OF TEN BRAZILIAN FROGS (ANURA) [PDF]

open access: yes, 2008
Basic data on habitat, behavior, and reproduction arelacking for most Neotropical frog species and even highertaxonomic groups (Crump 1974; Haddad and Prado2005), particularly for those restricted to the AtlanticForest.

Estimation of the Reproductive Number Trend of the Novel Coronavirus ”COVID-19“ in Southern Iran from July to November 2020 [PDF]

open access: yesIranian Journal of Medical Sciences, 2022
Background: Effective measures to control COVID-19 should be based on an understanding of its epidemiological pattern and the evaluation of its prevalence in the community. This study aimed to examine the reproductive number (R) of COVID-19 and its trend

Lyapunov Functions for Tuberculosis Models with Fast and Slow Progression [PDF]

open access: yes, 2006
The spread of tuberculosis is studied through two models which include fast and slow progression to the infected class. For each model, Lyapunov functions are used to show that when the basic reproduction number is less than or equal to one, the disease ...
