Re: Disease Detectives B/C

You can also have hierarchical case definitions - suspect, probable, confirmed. Usually suspect may just have signs or symptoms, probables have those plus some epi linkage and/or nondefinitive lab result while confirmed have a lab test to support

Re: Disease Detectives B/C

What is the difference between Division B and Division C? As others have said, ideally Division C exams are more difficult - for Division B you should be able to define, describe and calculate, in Division C you should be able to discuss, explain and evaluate. Division C includes experimental error...

Re: Disease Detectives B/C

monumentai -

Tough to be put into something you're not prepared for at the last minute but it sounds like you did your best and certainly came out of the experience with a great attitude. How one responds to adversity says a lot about character and you can be proud. Good luck in the future.

Re: Disease Detectives B/C

Do not rely on your cheat sheet. You will pay in time lost for using it. After you've finished - a cheat sheet might be useful in checking things you are unsure of but that is about it. As for stats - it is more important to be able to use, interpret and understand them than to calculate them. Compu...

Re: Disease Detectives B/C

Sorry, one more question; I was looking at some old tests on the 2016 exchange for practice, and many had some statistics (standard deviation/Z measure/Chi-squared/etc...); what statistics are required for division B ? Although one could argue the point, not all calculations used by epidemiologists...

Re: Disease Detectives B/C

is this event very hard, I've never done it before but am very interested. It isn't very difficult. It just has many aspects to it. I suggest you start studying the basics such as modes of transmission and calculations of measures of risk, but from this being my third year I have began to notice th...

CDC is redesigning its Sci Oly-Disease Detectives website

I understand that CDC is thinking of redesigning the Science Olympiad/Disease Detectives part of its website at http://www.cdc.gov/excite. It is not intended to compete with SciOly.org and is not likely to be very interactive but the prime target group is Science Olympiad Disease Detectives competit...

Re: Disease Detectives B/C

I guess I would start with the basic rates - know what they are and how they are calculated, modes of transmission, different types of studies (case-control, cohort), steps to an outbreak investigation, sensitivity/specificity, criteria for causation. If you know these and can use them well - to the...

Re: Disease Detectives B/C

How well you need to know the material depends on the level you are competing at and how well you expect to do. If you are competing in a regional middle school tournament and are satisfied with just not embarrassing yourself and your school too much - a perfunctory knowledge of the glossary in Prin...

Re: Disease Detectives B/C

We have little control over what is asked at the Regional and State competitions but I would suggest using Principles of Epidemiology 3rd edition (available free online from CDC) as a resource. We use it as the basis for our national competitions - those are the definitions, terms, principles, categ...
