sudden
acute
latent
What immediately follows acquiring an infection?
convalescence
prodromal stage
malaise
decline
What is the last stage of a disease?
convalescence
malaise
prodromal stage
exposure
Different pathogens can affect different parts of the human body because they are designed ______________.
not to have to compete with other pathogens
not to invade minor body systems
to attach to certain types of cells
to attack the area that they are exposed to first
What makes pathogens able to only affect specific hosts and organs?
genetic material
cell receptors
toxins
cell membrane composition
Which type of polio vaccine was used first in the United States?
Injected, living virus particles
Injected, dead virus particles
Oral, living virus particles
Oral, dead virus particles
Poliomyelitis and poliovirus are different from each other because ____________.
Poliovirus is found only in humans
Poliomyelitis is found only in tropical climates
Poliomyelitis is found only in the U.S. and poliovirus is found only in under-developed countries
There is no difference between them
What is poliomyelitis?
A form of the polio virus.
The name for the oral polio vaccine.
Paralysis that is a rare adverse reaction that can occur following vaccination with the live oral polio vaccine.
Paralysis that is a rare adverse reaction that can occur following vaccination with the dead polio vaccine.
20. Variola virus is the agent of _________
AIDS
HIV
Smallpox
Polio
21. The host for smallpox is___________.
Humans
Animals
Insects
All of the Above
26. From which virus is the smallpox vaccine derived?
Vaccinia
Adenoviradae
Iridoviridae
Guttaviridae
29. Why is there no antibiotic to kill HIV?
Antibiotics only kill living particles
None are effective against retroviruses
The virus “morphs” too quickly for an antibiotic to be developed that would kill it
Antibiotics that could kill HIV are too lethal for the patient
30. What does the name AIDS tell us about the disease?
The patient’s body exhibits no immune response to any stimuli.
There is no genetic reason to have the disease; its cause is environmental.
There is an overreaction of the patient’s immune system to stimuli.
There is a normal immune response in an individual, but the overproduction of white blood cells produce HIV.
31. Why are opportunistic infections a problem for an AIDS patient?
AIDS decreases CD8+ cells, which would typically kill the infection.
AIDS wipes out CD4+ and CD8+ cells, preventing immunity from most infections.
AIDS decreases CD4+ “warrior” cells that would typically lead the attack against an infection.
AIDS increases CD4+ “killer” cells, which kill white blood cells.
32. How does your body try to fight HIV?
By creating antibodies to fight the virus.
By getting a high fever to kill the virus.
It does not attempt to fight the virus.
The immune system is completely destroyed upon infection, so the body is unable to put up any resistance.
35. When HIV infects humans, which cells does it infect most often?
CD8+ cells
CD4+ cells
Macrophages
Microphages
46. The allele that causes an individual to be resistant to HIV may have evolved as a resistance to __________.
Tuberculosis
Black Death
Malaria
Bubonic plague
2W. Which class of virus is characterized by a single negative strand of RNA?
Class I
Class IV
Class V
Class VI
