You go to visit a friend who has chickenpox. While visiting what are 2
things you will be sure to avoid so that you don't also become infected? -
THE CORRECT ANSWER -1) keep a distance if your friend is coughing
or sneezing: chickenpox transmitted through airborne droplets
2. avoid direct contact with blisters of an infected individual.
True or False. The development of shingles is most often seen in an
older adult population (> 60 years old). - THE CORRECT ANSWER -
True: The most common age for VZV reactivation and shingle diagnosis
tends to occur in people around 60 years of age.
True or False. Unlike chickenpox, the blisters that appear with shingles
are localized and limited to small areas. - THE CORRECT ANSWER -
True: While chickenpox blisters often cover the en!re body, the blisters
associated with shingles are localized and limited to small areas.
A person who has never had chickenpox nor administered the
VZV/shingles vaccine is exposed to someone with an active VZV
(shingles) outbreak and becomes infected.
Explain why (or why not) the person will only develop shingles. - THE
CORRECT ANSWER -The infected individual will NOT develop shingles
but WILL develop chickenpox
, - Unvaccinated and unexposed individuals first develop chickenpox
because shingles is the reactivation of the dormant VZV virus from the
chickenpox infection.
What linear, double-stranded, enveloped DNA virus is the first virus (as
of Oct. 26, 1977) to be officially declared eradicated? - THE CORRECT
ANSWER -Smallpox (Variola virus).
What small (~30nm) single-stranded, non-enveloped RNA virus targets
the CNS, causing potentially catastrophic damage to motor neurons? -
THE CORRECT ANSWER -Polio, also known as poliomyelitis.
Describe the main underlining differences between the Salk and Sabin
polio vaccine. - THE CORRECT ANSWER -- Salk vaccine: contained
inactivated form of virus and was injected
- Sabin vaccine: contained a live attenuated (weakened) form of the
virus and was administered orally
Which subtype of Influenza is the most virulent? - THE CORRECT
ANSWER -Influenza A
A drug company is trying to develop a new drug that will inhibit the
release of newly produced viral particles. Would the drug company
target hemagglutinin proteins or neuraminidase proteins? - THE
CORRECT ANSWER -- Neuraminidase (N) proteins because they are
directly involved in the budding and release of new viral particles
Explain why the flu shot given each year may not be 100% effective at
preventing the flu? - THE CORRECT ANSWER -It is possible if you are
exposed to a viral strain that was not included in the vaccine
- large number of variants and the flu vaccine is unable to vaccinate
against all subtypes
