It is a Tuesday evening at 4:59pm and you are leaving the local health department where you serve as the lead epidemiologist. The phone rings, when you answer, it is the Health Services director at a local, residential college.  The students arrived on Campus on Saturday, by today, several dozen students have reported to the college health clinic with nausea, vomiting, stomach cramps and diarrhea.  The first student reported to the clinic at 8:15am, by 4:30, the clinic had seen 3 dozen cases.  There are 3001 students at the college.

The next question asks:

What is the current attack rate of the disease? (show your work)

I'm slightly confused by this. I'm assuming you divide 3 dozen, which is 36 by the total number of students, which is 3001.

Therefore, the attack rate is: \(\frac{36}{3001}\times 100\%=1.2\%\)

Hope we're on the right track Slight Smile
