### Re: Disease Detectives B/C

Sorry if this is long... I got carried away.

General questions
1. Distribution is defined as the _________ and ____________ of the disease. (fill in the blanks)
2. Define surveillance.
3. The epidemiological triangle is made up of what 3 (or 4) things?
4. Define latency period.

Outbreak investigation
5. Drake hosted a party in celebration of the launch of "More Life." 314 people at the party ate from the buffet, which contained food contaminated with a pathogen. In total, 159 people who attended the party were infected with the pathogen. Of those, 2 died as a result of the disease. Many of those infected experienced an onset of vomiting within 6 hours of exposure. Many also experienced watery diarrhea and abdominal cramps between 5 and 35 hours after exposure.
a. What is the case fatality rate for this outbreak?
b. Based on the symptoms, name one pathogen that might have caused this outbreak.
c. If 89 people at the party did not eat from the buffet, and 7 of them were infected with the pathogen, calculate the relative risk of infection associated with eating from the buffet.

Hm, may I see your work? I got a different answer of 1.17 cases per 1,000 person-years. This is the source I used: https://www.cdc.gov/ophss/csels/dsepd/s ... tion2.html
