Okay, I have yet another question (lol)
I can't seem to find a consistent mortality rate formula. Is the one featured on this webpage, http://health.mo.gov/training/epi/CrudeRate.html correct?
(it's Mortality Rate = deaths occuring during a given time period/size of the population which the deaths occurred * 10^n)
Also, I can't find one for attack rate

I believe it's # of deaths/population size for a specified unit of time.. It's literally just how many people die in a certain population, and isn't exactly the best measure (especially the crude mortality rate, which includes all sources of death and isn't a great metric). Don't worry too much about it.

Typically, though, mortality rates will be reported on a per thousand, per 10,000 or (most common, I think) per 100,000 population basis.

Also, that ID section may be mostly an NJ thing. Doesn't show up much on NY tests.

Hey! So this is my third year doing Disease Detectives, and they've never threw specific diseases on there besides just knowing the basics. What should I study about ebola? Thanks! :ugeek:

Well, we saw them at NY and PA invitationals so it may be a mid-Atlantic thing.

Definitely know that it's a hemorrhagic fever, caused by a virus, and a few of its symptoms. That should be sufficient.

I don't recall ever encountering an ID section in Disease Detectives. Maybe it's a new thing they're integrating, but as far as I know, it's not typical, and probably not necessarily something you should spend much time on.

Maybe...we've seem them a lot in NY/PA tournaments, but that could be our bad luck. Still, it's good to have a section devoted to listing the specifics of certain diseases - tiebreakers and short answers tend to focus on individual ones.

We are really confused about identifying point source, continuous source, and propagated epi curves. On certain tests it is really hard to identify the type of curve just according to the definitions. Can someone provide guidance on where we can find more information on identifying these curves?

Here is a source with sample graphs and explanations.

I feel you. This was my problem the first two years of the event. Just sit down and try to understand, it's not too difficult if you understand basic epidemiological terms. Don't fret too much, because it's easy to over complicate them! :D
