For the basic epidemiological and public health terms, do we have to know and define every term we can find?
What exactly do we have to do for this event? There is so much information given that it gets a bit confusing.

Is there any good way to split up the work between two members of a team without having each member learning the others topic?

Ask this here in the Disease Detectives Forum: http://scioly.org/phpBB3/viewtopic.php? ... 53#p282653 You'll probably get more help.

Case control. Deduce to cohort or case control based on "relationship between a specific exposure and a disease".  Out of the two it's case-control (stated in http://epi.publichealth.nc.gov/cd/lhds/manuals/cd/training/Module_1_1.6_ppt_OutbreakInvestigation.pdf, not quite sure why, probably a good thing to search)
Your turn yay I get to screw up again
Darn I knew it was one of those two. What's the chain of infection? (Define each term in order)
An infectious agent (a bacteria, virus, etc.) leaves a reservoir (a place where it can multiply) through a portal of exit. It then infects a susceptible host (someone who cannot stop the agent from multiplying and causing an infection) after being conveyed through a mode of transmission and going through a portal of entry.

Good job. Your turn.

What is the difference between incidence and prevalence? Explain how each is calculated.

Incidence is the measure of the rate of new cases occuring in a specified population, while prevalence is the proportion of cases currently present in a specified population

Incidence is # of new cases/time observed/period
Prevalence is # of cases present during a time period/population
