Question 3

denominator

Answer 3

population at risk

Question 4

incidence rate

Answer 4

rate of new cases appearing in a population during a period of time
new cases/ 100,000

Question 5

prevalence

Answer 5

frequency in a population at any given time total cases/ 100,000

Question 6

mortality rate

Answer 6

deaths that occur within a population over a specific period of time (deaths/100,000)

Question 7

Epidemic Curve

Answer 7

Graphs when an outbreak is & the number of cases day by day
can help calculate the time of incubation and the infectious window
as cases go down, the transmission slows

Question 8

Cohort Study

Answer 8

This study design involves following a group of people over time to determine if an exposure (e.g., smoking) is associated with an outcome (e.g., lung cancer)

Question 9

Case Control

Answer 9

In this design, people with the outcome (cases) are compared to those without the outcome (controls) to determine the probability of previous exposure to a risk factor (e.g., smoking)

Question 10

Intervention study
