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

Iranian 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.

Convex Optimization of the Basic Reproduction Number

IEEE 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.

The basic reproduction number for scrapie [PDF]

Proceedings 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.

A network immuno-epidemiological model of HIV and opioid epidemics

Mathematical 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 (R0) for the novel coronavirus disease in Sri Lanka

Virology Journal, 2020
Background The basic reproduction number (R0) is the number of cases directly caused by an infected individual throughout his infectious period. R0 is used to determine the ability of a disease to spread within a given population. The reproduction number
