I'll do another vocab question:

What does specificity mean?
The proportion of persons without disease who are correctly identified by a screening test or case definition as not having disease

A vector is an organism that transmits disease.   Examples include mosquitoes (transmit malaria) , possibly dogs (transmit rabies) and ticks (transmit lime disease)

I have an idea, I'll wait 3 days before answering a question on here, if somebody doesn't answer it by then, I will.

What are false positives and false negatives and why are they important when investigating an outbreak?

Okay, not a bad idea...
False Positives are where you say something is false even though it is true.
False Negatives are where you say something is true even though it is false.

False Positives occur when there is enough random variation in the population to assume that something has changed, on the other hand False Negatives occur when the change is too small to think much has changed.

Umm...here's a question!

What's the difference between an outbreak, an epidemic, and a pandemic?

Here are my tries:
Outbreak: occurrence of more cases of a health condition than usual in a given area. Epidemic: a widely dispersed, rapidly spreading occurrence of disease in an area. Pandemic: an epidemic on a global scale.
'16, she/her, environmental-scientist-to-be: green gen, invasives, disease, ex. design, widi.
