I think
1. Microorganisms have to be found in all organisms that have the disease but not in the ones that don't.
2. Microorganism has to be separate from organisms with the disease.
3. Microorganism must cause a disease.
4. Uhh... Said microorganism must be the same as another microorganism (?)

Kochs postulates:
Pathogen is present in every case of the disease, can be isolated from host and cultured, can be used to infect animals in the lab, and then be isolated from that animal again, right?

A vector is
A quantity having direction as well as magnitude, especially as determining the position of one point in space relative to another. Or
An organism, typically a biting insect or tick, that transmits a disease or parasite from one animal or plant to another.


The most recent and severe flue epidemic was
The H1N1 of 1918

The point of Question Marathons is for people to pose questions and others to answer them. For example:
Person 1 wrote:What are the three main modes of transmission?

Person 2 wrote:Airborne, Vectorborne, and Vehicleborne.

Correct! Your turn. (Susan, your answer is correct too, but since Froggie answered first, I'll let him ask the next question)

To be a bit more specific
There is an index case (the first case) followed by a sudden spike in cases roughly one incubation period later. There is little person-to-person transmission, so the outbreak does not last much longer than one incubation period after the date of the index case, and accordingly the graph slopes back down quickly.
