A measure of the transmission potential of a disease, which corresponds to the number of secondary infections produced by a typical case of an infection in a population that is totally susceptible, and can be quantified by counting the number of secondary cases following the introduction of an infection into a totally susceptible population. Unfortunately when vaccines are not given, serious illnesses can spread freely.

The latter, a phenomenon called herd immunity , occurs as more and more people get vaccinate further restricting the ease with which the disease-causing germ can spread. Though there has been a tendency to emphasize the eradication implications of herd immunity in much of the theoretical literature, eradication programs are the exception in public health, because most programs aim at disease reduction to some “tolerable” level.
