D) Infectious disease epidemiology

Answer 1

Infectious disease epidemiology

Question 2

Which of the following is the only infectious disease to be successfully eradicated globally?

A) Smallpox
B) Poliovirus
C) Dracunculiasis
D) Tuberculosis

Answer 2

Smallpox

Question 3

In infectious disease epidemiology, a case is a person who has been exposed to an infectious agent.

Answer 3

False

Question 4

An animal or insect that carries an infectious disease is called an):

A) Vector
B) Host
C) Microbe
D) Fomite

Question 5

Which scientist proposed that if a microbe was responsible for a specific disease then it should be possible to isolate that microbe from an individual with the illness, grow the microbe in a laboratory, infect another individual, and re-isolate the same microbe from the newly infected individual?

A) John Snow
B) Robert Koch
C) Louis Pasteur
D) Antoine van Leeuwenhoek

Question 6

If you create an epidemic curve for an outbreak and see that there are multiple peaks in the number of infections over time, indicating the disease is spreading from person to person, what type of outbreak has occurred?

A) Point source
B) Propagated
C) Continuous source
D) Vector-borne

Question 7

A vaccine that is made up of an infectious microbe that has been altered weakened) in the laboratory so that it will cause an immune response but will not cause illness is called an):

A) Live vaccine
B) Live attenuated vaccine
C) Inactivated vaccine
D) Component vaccine

Question 8

Dracunculiasis Guinea worm disease) is a vaccine-preventable disease that requires a single dose for lifelong immunity.

Question 9

The final step of an outbreak investigation should be to report the findings to others so that future outbreaks might be prevented.

Question 10

Severe Acute Respiratory Syndrome SARS) was a completely unique type of coronavirus that had not been seen before it caused a pandemic in 2002.

Question 11

An infectious disease outbreak occurs when there is a higher than expected number of cases of a particular disease.

Question 12

The descriptive epidemiology practice of identifying person, place, and time factors is also used in infectious disease epidemiology to describe an outbreak.

Question 13

Which of the following factors makes a disease a good candidate for eradication?

A) It mutates frequently
B) There is limited funding available in developing nations to control the disease.
C) There are multiple animal reservoirs.
D) It can be prevented with a single dose of vaccine.

Question 14

In infectious disease epidemiology, what measure is a useful indicator of the severity of an outbreak, calculated as the number of cases out of the number of susceptible people?

A) Relative risk
B) Odds ratio
C) Attack rate
D) Incubation period

Question 15

When an infectious disease is spread by contact transmission, the source releases the microbe into the air, usually by breathing, coughing, or spitting, and the host is exposed.

Question 16

Which of the following terms is used to describe the phenomenon that not all members of a community must be vaccinated in order to protect the community from an infectious disease outbreak?

A) Eradication
B) Variolation
C) Herd immunity
D) Inapparent infection

Question 17

The process of identifying people who came into contact with an infected person is known in infectious disease epidemiology as the chain of infection.

Question 18

Poliovirus is spread through the fecal-oral route and causes inapparent infection in the vast majority of people who contract it.

Question 19

The emergence of Human Immunodeficiency Virus HIV) has led to an increase in the number of cases of which other infectious disease, previously in decline for over 30 years?

A) Smallpox
B) Poliovirus
C) Dracunculiasis
D) Tuberculosis

Question 20

Variolation, an early practice of preventing the spread of disease, was developed using an influenza-like virus from pigs and infecting humans to prevent more serious disease.
