Disease Detectives

I had that question too. We just did number of sick people over total number of people for incidence ratio.
For cumulative incidence ratio, we divided never smokers' incidence rate by ever smokers' incidence rate or vice versa, I can't really remember.
Do you remember the question with Koch's postulates on that test? What did you get?

For our regional, it was all statistical analysis and terminology. Last year's course in Stats helped a ton. I did not prepare for the event and I'm not sure if preparing much more would've helped (we didn't know what incidence rate was, but it it could be deduced from the evidence and wording provided). We managed to pull of a win, but I have no idea if it was just pure dumb luck.

so i am first timer to disease detectives. can someone give me some advice?

Read the DiseaseDetective Wiki......if you know all of that, you should get the bulk of the points....know how to apply it as well

that's what we did!!
for the koch's pstulates i think we wrote c not sure. it was something about re-quarantine the agent w/ the pathogens or something, i can't remember

What math (formulas/equations) actually would you need to know for Disease. I know you would need to know: Odds Ration, Relative Risk, Risk, Incidence, Prevalence, Case Fatality Rate. What else?

[doctor]

attack rate

[pjgscioisamazing]

attack rate

OK that's one more.
Cos it's:
Odds Ratio: ad/bc
Relative Risk: (a/a+b)/(c/c+d)
Case Fatality rate: # of people who died/ total # of cases

What are the equations for teh other ones (risk, incidence, prevalence, attack rate)

[doctor]

attack rate is a/a+b
i think so it would be ppl who died/sick divided by the total population

ok cool. Do you know any of the other ones I mentioned? If you don't I'll check the wiki/internet, but I think it is good practice to have the competitors help each other out and such.
