1) You are exposed to influenza viruses, and alas, you have notyet had your influenza vaccine this year! Unfortunately, theviruses manage to bind successfully to epithelial cells in yournasal passageways, initiating an infection.
a) Follow the pathway of a single virus as it initiates itsinfection, resulting in the production of numerous virusparticles.
b) Describe your immune system and its response: both innate(first line, that was breached, and second line of defense) andadaptive. Which components may not have played a role in protectingyou, and which ones will ultimately hopefully clear thisinfection?
2) Consider a group of humans all exposed to pathogens (i.e.,the same disease-causing organism, but presumably a population ofsuch!) Examples might be a group of people eating at a restaurant,or all exposed to a respiratory pathogen in a shopping mall,classroom, or on an airplane, etc.
a) Would everyone come down with the illness? Why or whynot?
b) If not, how would you explain the variability in response interms of 1) differences attributable to pathogens and 2)differences attributable to humans?
