CNUR401 Final Review– Comprehensive Study Guide and
Practice Questions
Emerging infectious disease - correct answer ✔✔those in which the incidence has actually
increased in the past two decades or had the potential to increase in the near future
How is west nile virus spread? - correct answer ✔✔new to Canada and by mosquitos
what is Anthrax caused by? - correct answer ✔✔spore forming bacterium Bacillus anthracis.
highly resistant to disinfection and environmental destruction
What is avian influenza? - correct answer ✔✔birds that transmit it to humans
what is H1N1? - correct answer ✔✔a strain of influenza that is transmissible to humans
what is middle east respiratory syndrome? - correct answer ✔✔a viral respiratory illness that is
new to humans
cryptococcal disease - correct answer ✔✔fungal infection
Hantavirus Pulmonary Syndrome - correct answer ✔✔disease caused by the hantavirus that
begins with flu like symptoms and become life threatening because it can affect the lungs and
cause respiratory problems. carriers are deer mice and affects humans from inhaling the virus or
by ingestion
necrotizing fasciitis (flesh eating disease) - correct answer ✔✔condition that follows a skin
injury that is caused by the group A streptococci
,E coli - correct answer ✔✔strain of the E. coli bacteria that is transmitted through the
consumption of contaminated food. can cause severe diarrhea, kidney damage and death. often
arises as a result of lower standards of water quality, sanitation, and food prep
Bovine Spongiform Encephalopathy (mad cow disease) - correct answer ✔✔transmitted
through the consumption of contaminated beef
Creutzfeldt-Jakob disease - correct answer ✔✔fatal disease that affects the CNS. two types
including classic and variant. can cause severe acute respiratory syndrome with no definitive
treatment
Classic Creutzfeldt-Jakob Disease - correct answer ✔✔CJD that occurs in the general population
without a known ccause
Variant Creutzfeldt-Jakob Disease - correct answer ✔✔CJD that is linked to eating beef
communicable disease - correct answer ✔✔contagious disease of the human or animal origin
caused by an
infectious agent
transmission - correct answer ✔✔depends on the successful interaction of the agent, host and
environment
what is the goal of preventing communicable disease? - correct answer ✔✔Goal is to reduce
prevalence to a level at which the disease no longer poses a
major public health problem
goal of elimination - correct answer ✔✔remove disease from a large geographical area
, goal of eradication - correct answer ✔✔permanently eliminate disease worldwide
agent factor - correct answer ✔✔described as the ability to cause disease and by the nature
and severity of disease
environmental factor - correct answer ✔✔all that is external to the human host that facilitates
transmission
host factor - correct answer ✔✔human or animal host that can harbour and infectious agent
resistance - correct answer ✔✔ability of the host to withstand infection (natural or acquired
immunity)
natural immunity - correct answer ✔✔innate resistance to infectious agent
acquired immunity - correct answer ✔✔resistance due to previous natured exposure
active immunity - correct answer ✔✔immunization against an agent through vaccine
passive immunity - correct answer ✔✔transfer of antibodies from immunized to non-
immunized person
herd immunity - correct answer ✔✔immunity of a group of community. resistance to an agent
based on high number of the individuals being immune to an infection
infectiousness - correct answer ✔✔measure of the potential ability of an infected host to transit
infection to other hostts
