18. In the investigation of an epidemic of food poisoning at a banquet, high attack rates were found for people who ate roast beef as well as those who ate mush room sauce. Table 1 shows combinations of the two foods that were then considered. Calculate appropriate Attack Rates.  

Solution

14.

There are 974 cases out of 3465 women.

Thus,

prevalence = 974/3465 = 0.281096681

or

prevalence = 28.11% [answer]

****************************

15.

During the first quarter, a total of 112 + 10 + 6 = 128 cases.

Thus,

prevalence = 128/210000 = 0.000609524

or

prevalence = 0.06095% [answer]

***************************

16.

We are just talking about the holiday.

So, there are 22 out of 65000 that have injuries requiring hospitalization.

Thus,

prevalence = 22/65000 = 0.000338462 = 0.0338462% [answer]

************************

17.

For the entire period, the total number of cases is 22 + 8 = 30.

Thus,

prevalence = 30/65000 = 0.046153846% [answer]
