Question 17

Question 19

1 / 1 pts

Which of the following could be an exposure variable?

Behavior

Pathogens

Environment

All of the above

Question 20

1 / 1 pts

Point incidence is

There is no such thing as point incidence because incidence must always be determined over time.

New cases examined at just one point in time.

Used in every epidemiological study.

Question 21

1 / 1 pts

A rate can be represented as a

1 / 1 pts

Incidence is

New cases of a disease

Existing cases of a disease

Number of people in the population

People at risk of a disease

Question 23

1 / 1 pts

What is a suspect case?

A patient who meets all of the characteristics and symptoms of a case but does not have a formal diagnosis.

The person responsible for an epidemic, also known as the index case.

A patient who has been diagnosed with a case but has no or few symptoms at the time of diagnosis.

An outbreak of bioterrorism, such as Anthrax.

Question 24

1 / 1 pts

Prevalence is

Existing cases of a disease

New cases of a disease

People at risk of a disease

IncorrectQuestion 25

0 / 1 pts
