This event seems so confusing!!!!!!! :? Can anyone explain to me what we have to learn? I know there is a certain type of graph and that we have to know some vocabulary, but what else? Could you explain that again, in more simple terms? Please? :oops:
For this event, you need to understand how outbreaks of diseases are investigated. This involves interpreting data, being comfortable with terminology, and showing good understanding of the presented scenarios.

There are more than enough resources on the Science Olympiad event page
A VERY good place to start is with the Training Handout
You can also take a look at the PowerPoint, and at the SciOly Wiki page.
Once you're comfortable with the event, you can do somepractice tests.

Good luck!
Thank you! Good luck to you too! :lol:

Does anyone really understand what this event is about? I thought at first it was just about diagnosing a food borne-illness. So should we be studying epidemiology too or what?... confused but getting there

This event is all about epidemiology. Your main task in the event will often be to follow epidemiological procedure on several case studies. You'll have to calculate comparative rates and ratios, evaluate and apply different epidemiological study designs, and suggest courses of action to prevent or combat epidemics. Sometimes you'll get questions about diagnoses, but by no means is that a major part of the event.

I don't mean to be rude here when I say this, but it might come off as such because I'm tired and beginning to get sick, so bear with me.

When you're new to an event, and you come to the forums for help, please do not just ask "What do I need to know to be good at this event" or "What is this event about." You waste everyone's time. You should have a copy of the rules, and they list everything you need to know. If you have questions about what a certain part of the rules mean, or don't understand a certain topic, feel free to ask, and people will be more than happy to help. But don't walk in here and say "Teach me" and expect to get anything worthwhile out of it.

Anyways, looking forward to this event again this year, hoping to grab a gold for the first time. Gonna be rough since Solon is the reigning champion in the event, but I should be able to sneak one out, or get it at regionals when Solon isn't there.

Um, excuse me? I asked for help on this because I lost my copy of the rules, so i asked so I could get working. And also, even though you think I didn't get anything out of this, I learned that the wiki existed and how to get to the practice tests. And while I can't speak for everyone, I feel your comment was slightly rude, although I can see where you were coming from. Sorry if this angers you. I'm not looking for a fight.

So, I'm doing this event again this year, and I was wondering: What food-borne illnesses do you guys memorize the symptoms and stuff of - if any at all? I have some basics down, like Botulism, Clostridium, E. coli, Listeriosis, Salmonela, Shigella, and Staphylococcus. I've taken multiple tests where they have matching questions on associated foods and symptoms, and also others where food-borne illness is only incorporated in the outbreak, so I was just wondering if you guys had any other food-borne illnesses that are pretty common and often appear on tests. Thanks in advance!

That list you have should be plenty. (I'd include Trichinosis, though.)
The most important ones are E. Coli and Salmonella.

Can someone explain the difference between Cohort and Case Control? For instance, when one would be used as opposed to the other? I know one compares the exposed and non-exposed vs those with the disease and not - however, what is the real difference between Odds ratio and Relative Risk?

Well, I just started learning this event, but I'm pretty sure relative risk is "the association between an exposure and a disease. It estimates the likelihood of developing the disease in the exposed group as compares to the unexposed group." Basically, it determines how likely it is that something caused the disease. Odds ratio is kind of finding out the percent chance of contracting a disease. Say if a restarunt was suspected of making people sick. The odds ratio would conclude something like "People who ate at Restaurant A were 5.8 x more likely to contract Hepatitas A then people who did not eat there." I know this is kind of a confusing explanation. Sorry! I hope this is a little less confusing then I think it is. :D

Phrases in quotation marks and examples were taken directly from my Training Handout. If you recieved it, it has a lot of info on odds ratio and relative risk.
