## HOw do you find the relative mortality?

### take rate exposed divided by rate unexposed

10

## How do you find mortality diffference?

### subtract rate exposed by rate unexposed

11

## What is a PUI?

### a person who touched something questionable in the last 21 days

12

## What is the definition of legionnaires?
