This concept will apply to bacteria also. We are all exposed to
microorganisms yet seldom get sick from them. You can quantitate the
number of people or animals who are exposed vs. the number who fall ill
to the infection. You can also quantitate the number of fatalities in
the population that does get sick.
Does that help?
