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.

Estimation of the basic reproduction number (R0) for the novel coronavirus disease in Sri Lanka

open access: yesVirology 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

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.

Estimating the Basic Reproductive Number from Viral Sequence Data [PDF]

open access: yesMolecular Biology and Evolution, 2011
Epidemiological processes leave a fingerprint in the pattern of genetic structure of virus populations. Here, we provide a new method to infer epidemiological parameters directly from viral sequence data. The method is based on phylogenetic analysis using a birth-death model (BDM) rather than the commonly used coalescent as the model for the ...

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
