Abstract:
The basic reproductive number (R
0
) is a threshold parameter for a population-level model of infectious disease control. The basic reproduction number
is derived by epidemiologists using different techniques. It is used to estimate the basic reproductive rates of infected and susceptible hosts and to
guide intervention strategies. In this paper, we give an overview of the methods used in the derivation of R
0
and assess the use of R
0
in the literature.
Finally, we discuss some of the limitations and alternatives to the basic reproduction number that have been identified in the literature. The main
contribution of this paper is to provide a guideline and shed light on the basic reproduction number to mathematical modellers and policy makers
in order to prevent the possible blown out of the epidemic in the susceptible population.
