Questions All Solved.
Morbidity rate is an important parameter used by epidemiologists to measure disease. If there
are 10 new cases of measles per 10,000 individuals in a population in a two-month period, the
morbidity rate is _______________. - Answer 0.1%
The first epidemiologist was ___________. - Answer John Snow
Control measures should be directed toward the part of the infectious disease cycle that is
_________. - Answer most susceptible to control
Brian lives in a town where 98% of the population is immunized against measles. Brian is
unlikely to get measles, despite the fact that he has never been immunized. This situation
demonstrates the concept of - Answer herd immunity
The vaccine used to prevent measles consists of live measles viruses. This type of vaccine is
most likely - Answer an attenuated vaccine
A subunit vaccine is composed of - Answer purified parts of a microorganism
T/F. Vaccines made from attenuated microorganisms are better at boosting the immune
response than vaccines made from inactivated microorganisms. - Answer True
T/F. Vaccines present antibodies from a pathogen to stimulate immunity. - Answer False
The U.S. government has invested national effort into creating a biological weapons defense.
The initiatives include:
(check all that apply) - Answer - development of improved detection and diagnostic systems
- preparation of clinical microbiologists and their laboratories as first-responder teams
- a stockpile of specialized vaccines and medicines for civilian protection
The total number of individuals infected in a population at any one time is referred to as -
Answer prevalence rate
Epidemiology - Answer The study of the origin, cause, distribution, and spread of disease
, What were John Snow's studies? - Answer Studied series of Cholera outbreaks; discovered
the disease came from infected drinking water
T/F. Control measures for microorganisms should be directed toward the part of the disease
cycle that is most susceptible to control. - Answer True
What governmental agency focuses on national and environmental health, as well as designs a
set of health education activities to improve general health of the population? - Answer
Center for Disease Control and Prevention (CDC)
What is the supranational agency involved in tracking and controlling the spread of disease
worldwide? - Answer World Health Organizations (WHO)
What is the U.S. Biological Weapons Defense Initiative? - Answer Based on developing,
producing, and stockpiling specific antibody reagents hat can be used to protect the population
against biological warfare threats
Sporadic disease - Answer Occurs occasionally, at irregular intervals
Endemic disease - Answer Occurs regularly at a low level of frequency and at moderately
regular intervals
Hyperendemic disease - Answer Increases gradually above the level of an endemic disease,
but not enough to qualify as an epidemic
Outbreak - Answer An abrupt, unexpected occurrence of a disease, usually in a limited
segment of the population
Epidemic - Answer An abrupt increase in the frequency of the disease above the expected
number
Index case - Answer First case in an epidemic
Pandemic - Answer An increase in the occurrence of disease within a large population
What does public health surveillance involve? - Answer The proactive evaluation of emerging
infectious agents, human behaviors, lifestyle choices, and genetic backgrounds
T/F. Epidemiologists frequently draw on knowledge from the field of statistics. - Answer True
