Time for me to start studying for this event again...
Assuming I'm just suppose to halve the number lost to follow up and add it on: 0.0521
Hm, may I see your work? I got a different answer of 1.17 cases per 1,000 person-years. This is the source I used: https://www.cdc.gov/ophss/csels/dsepd/s ... tion2.html
I also got that answer. I added it up and ended up doing:
answer
16 new cases in 13710 person-years for an incidence of 1.167 cases per 1000 person-years.
Ok, that makes a lot more sense. I had no idea what you meant by "assume those lost to follow-up are disease free for half of the year;" apparently I didn't need that?

You still have to count them toward the person-years observed. I ended up with 13717.5 person-years. Ignoring them here just doesn't have much of an impact due to the number of participants. Feel free to PM me if you have anymore questions.

Your turn to pose a problem.
So much to do, so little time.

I'm assuming you're referring to only indirect transmissions

During the beginning of an outbreak investigation, should you use a specific or sensitive case definition, and why?

[spoiler]Depending on the deadliness of the disease, how fast it is traveling, and how many people are potential reservoirs, you should use different types of case definitions to possibly stop the disease faster.[/spoiler]

My answer
You should use a sensitive case definition, especially in the beginning of an out break investigation, in order identify as many possible cases as you can and implement treatments for the disease

Both seem like good answers...

In general, your case definition should be relatively sensitive. As the investigation continues, you can refine the case definition and drop suspected cases from the case definition.

What are the two types of misclassification bias? In what types of studies are they usually found?

---
Nondiffrential and differential. They are typically found in observation studies
What is the most accurate measure of risk?

I'm a little rusty on this event but hopefully I remember this
Relative risk; however, it requires a complete control group so it sometimes cannot be used.
