The basic reproduction number is not to be confused with the effective reproduction number $${\displaystyle R}$$ (or $${\displaystyle R_{e}}$$), which is the number of cases generated in the current state of a population, which does not have to be the uninfected state. Online demography calculator to calculate the number of live births per 1000 women between the ages of 15 and 49 years using general fertility rate (GFR) formula.Fertility is a child bearing capacity of the population represented by women between the ages of 15 and 49 years. Blower and coauthors calculated from a simple model of TB the following reproduction number:In their model, it is assumed that the infected individuals can develop active TB by either direct progression (the disease develops immediately after infection) considered above as FAST tuberculosis or endogenous reactivation (the disease develops years after the infection) considered above as SLOW tuberculosis.In populations that are not homogeneous, the definition of During an epidemic, typically the number of diagnosed infections If an individual, after getting infected, infects exactly In this model, an individual infection has the following stages: c. Suppose now that age-specific fertility changes, so that women have (on average) one-half child at ages 25, 28, 32, and 35. First, we show how to calculate the net reproductive rate using a graphical approach. BibTeX

A New Method for Calculating Net Reproductive Rate from Graph Reduction with Applications to the Control of Invasive Species June 2007 Bulletin of Mathematical Biology 69(4):1341-54 The definition describes the state where no other individuals are infected or immunized (naturally or through vaccination). (2) applied to the single-node graph given in D: 1 − L(1) = 0, where L(1) = a12a21λ −2 The gross reproduction rate (GRR) is the average number of daughters a woman would have if she survived all of her childbearing years, which is roughly to the age of 45, subject to the age-specific fertility rate and sex ratio at birth throughout that period.This rate is a measure of replacement fertility if mortality is not in the equation.

2. It is calculated by adding up the average number of births per woman across five-year age groups (i.e. Définitions. A New Method for Calculating Net Reproductive Rate 1343 Fig.
