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

open access: yesJ Comput Appl Math, 2021
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.

Estimating epidemic exponential growth rate and basic reproduction number

open access: yesInfectious Disease Modelling, 2020
The initial exponential growth rate of an epidemic is an important measure of the severeness of the epidemic, and is also closely related to the basic reproduction number.

On the basic reproduction number $R_0$ in sexual activity models for HIV/AIDS epidemics: Example from Yunnan, China

open access: hybridMathematical Biosciences and Engineering, 2007
Heterogeneity in sexual behavior is known to play an important role in the spread of HIV. In 1986, a mathematical model based on ordinary differential equations was introduced to take into account the distribution of sexual activity.

Estimation of the basic reproduction number of measles during an outbreak in a partially vaccinated population [PDF]

open access: bronze, 2000
From March to July 1996 a measles outbreak occurred in northern Luxembourg with 110 reported cases centered around two primary schools (85 cases) and the surrounding community (25 cases). Eighty four suspected cases were confirmed serologically.

The Dynamic Effective Reproductive Number of COVID-19 during the Epidemic in Iran

open access: yesIranian Journal of Public Health, 2022
Background: We aimed to determine the generation time, the best model for estimating reproduction number (R), and to estimate the basic reproduction number (R0) and effective reproduction number (Rt) for COVID-19 in Iran.

The basic reproduction number for scrapie [PDF]

open access: yesProceedings of the Royal Society of London. Series B: Biological Sciences, 1999
The basic reproduction number R0 provides a quantitative assessment of the ability of an infectious agent to invade a susceptible host population. A mathematical expression for R0 is derived based on a recently developed model for the spread of scrapie through a flock of sheep.

Convex Optimization of the Basic Reproduction Number

open access: yesIEEE Transactions on Automatic Control, 2022
The basic reproduction number $R_0$ is a fundamental quantity in epidemiological modeling, reflecting the typical number of secondary infections that arise from a single infected individual. While $R_0$ is widely known to scientists, policymakers, and the general public, it has received comparatively little attention in the controls community.
