Interpret the meaning of an odds ratio if there is an odds ratio of 1.7 for a case-control study involving the link between E. coli and the lettuce from a certain Mexican restaurant.

Answer:People who eat lettuce from that Mexican restaurant are 1.7 times more likely to get E.coli than people who didn't eat the lettuce(or something like that).

Wouldn't that be the relationship though? Was my wording off anywhere or did I get the type of relationship wrong?

It's not 1.7 more likely; it's that [i]the odds are 1.7 times as much[/i]. Note that odds is different than risk/probability because it can be used in a case-control study. That said, the OR is not necessarily a good predictor of the RR. I would say something along the lines of "Eating lettuce at the Mexican restaurant and developing E. coli are somewhat related." Note that you can't establish causation or a specific probability.
Your turn!

What would a continuous common source epi curve look like?

Instead of a single peak, it'd have a long, prolonged span of new cases being developed.

What is a case definition and what are the criteria?

it is a standard criteria for determining who has the disease or condition. The case definition must have clinical information, characteristics of the people affected (i.e. age, occupation, gender), location, and the time.
