Attack rate - ANS-an incidence proportion, rather than a true rate,that is used to
measure the frequency of new cases of a disease or condition in a specific population
during a limited period. It is usually used to describe the proportion of the population
that develops a disease or condition during an outbreak.
The formula is
x÷y×10n
where x (the numerator) is the number of new cases or events in a population during a
given time period, y (the denominator) is the number in the population at risk during that
time period, and the result is usually expressed as cases per 100 population, or as a
percentage
