That will be up to each Event Supervisor (whomever is writing the test for that particular competition), but you can probably be pretty sure it will be one that has been covered in the past, only it will not devote as much time to it as in previous years. (See Part II: Outbreak Investigation of the manual).Does this mean that they can potentially test us about any of the 3 topics (that usually rotate)?
Generally, you will be tested on what's explicitly written in the rules. Note how the event has been restructured into three main topics.Does this mean that they can potentially test us about any of the 3 topics (that usually rotate)?
It can be calculated for whole populations, but it isn't - unless the whole population is considered at risk. They will be equivalent when the population is defined down to the at-risk population, as in eaters of the potato salad, or when the agent is so widespread that the risk is defined up to include the whole population, as perhaps in the case of the flu. However, in most cases they will not be the same as each other. One might report the incidence of Hep A for a county using the whole population as the denominator, but the attack rate would likely be calculated only for diners at a particular restaurant, or even only those who ordered a particular dish.Attack rate can be calculated for the whole population or exposed populations; it's just a measure or risk.They don't mean the same thing. Incidence figures are virtually always calculated for whole populations, and attack rates for exposed populations.Why is attack rate listed on part 2, then incidence proportion is listed on part 3, even though attack rate and incidence proportion mean the same thing?
I have to assume that they are talking about this:What even is the 5 step process for surveillance? I can't find it anywhere on the internet.I noticed on this year's event description, the section about C level doing advanced statistics is gone, replaced by a requirement they do more on confounding, biases and prevention measures. Does this mean we can stop trying to teach college statistics?!! Probably will be more clear on the new DD CD from Nationals.
They are also are trying to allocate the test emphasis more evenly on Background and Surveillance, Outbreak Investigation and Patterns, Controls and Prevention. If only our state event supervisor would take note of the changes...
Also new, the "5 step Process for Surveillance and the types of Surveillance".
And most importantly, this would normally be the year that the topic would be environmental sources of disease, but there is no mention of a special area to focus on this year under the Description paragraph. Anyone know if we are moving away from doing topics?!
Food-borne illnesses aren't part of the topic this year, so it will naturally vary between competition to competitionfor me, there weren't any food-borne related questions in the test I took
