Attack Rate
The attack rate is given by the formula (Ahrens et al., 2014),
Attack rate= number of new afflictions in the population under risk
size of population under risk
The number of attack for persons who ate either tuna salad or egg salad or neither or both is
given in the following table.
1.
The attack rate for people who ate only egg salad is given by,
number of sick persons who ate egg salad and did not eat tuna salad
number of people who ate egg salad and not tuna salad ×100 %= 25
50 ×100 %
¿50%
2.
The attack rate for people who ate only tuna salad is given by,
number of sick persons who ate tuna salad and did not eat egg salad
number of people who ate tuna salad and not egg salad ×100 %= 140
198 ×100 %
=70.70%
