Differentiate between pathogenicity, infectivity, and virulence.
Infectivity - ability of a pathogen to undergo horizontal transmission, or actually spread to another organism. This is taken without regard to whether the pathogen actually causes disease.
Pathogenicity - ability of a pathogen to actually cause disease once it has infected the host
Virulence - degree/extent to which the disease is; severity of the disease caused by pathogen.

Yep, your turn!

Something something no posts.
George sneezed in Lucas' face and Lucas caught his cold. Ptady, who was sitting across the room, also gets sick.
What two types of transmission are responsible here? Be specific.

Lucas - droplet
Ptady - airborne

You are conducting a study on [some disease] when a helpful friend tells you age may be a confounding variable.
1. What is confounding?
2. How can you modify your study design to account for this?
3. Which test statistic would you use after data collection?

1. If a variable is associated with both the exposure being tested and the disease/treatment being studied, but is not causally related to the exposure, then it is a confounding variable, or confounder.
2. Stratify or match the participants by age group, or just restrict the study to a certain age group (though the second may create further confounders).
3. Not sure exactly what's being asked; is this asking for a type of statistical test?
