Question 2

A number of viruses often include a similar set of symptoms when they cause an infectious disease state (fever, headache, fatigue, runny nose). Why would they all cause the same symptoms if they're different viruses?

Accepted Answer

A)  They all possess the same basic virulence genes and molecules, so they all trigger the same responses. 
B)  The symptoms are associated with the immune system's response, NOT the molecules from the pathogens themselves. Our responses against viruses are fairly similar, regardless of virus type, so the symptoms are similar. 
C)  Most viruses infect the upper respiratory tract. This leads to the common set of symptoms listed above. Only a few viruses infect areas away from this region. 
D)  Viruses specifically infect mainly epithelial membranes. As such, the virally induced reaction is similar in different areas of the body due to the same basic cell types (epithelial cells) being infected in each area. 
E)  All animal viruses must attach to and enter host cells. Since this step in the life cycle is identical in all viruses, the signs and symptoms that follow will also be identical.

Question 3

Select the INCORRECT definition regarding the progression of an infectious disease.

Accepted Answer

A)  Illness phase-period of time during which symptoms and signs of disease occur. 
B)  Incubation period-interval between the entrance of a pathogen into a susceptible host and the onset of illness caused by that pathogen. 
C)  Prodromal period-a period of early, vague symptoms indicating the onset of a disease. 
D)  Period of convalescence-period of recuperation and recovery from an illness. 
E)  Carrier phase-period in which a pathogen is harbored without noticeable ill effects, but may be transmitted to other hosts.
