Assignment:

1. Why can you get the flu over and over again throughout your life, even though your immune system prevents this with most other pathogens? How does this property of influenza affect its epidemiology the way it comes and goes in populations and how can we protect those most at risk?

2. We learned about five different herpes viruses: herpes simplex 1 and 2, herpes zoster (causes chicken pox/shingles), Epstein-Barr virus, and cytomegalovirus. Describe two ways in which these viruses are the same in their behavior in the human host, despite the very different diseases they cause.

3. A 6-month-old boy presents at the ER with lethargy, high fever, and labored breathing. His six-year-old brother has an upper respiratory infection. You are worried about meningitis or encephalitis. What bodily fluid(s) could help test this? What would be done with the fluid to get results quickly? How could the results help one determine whether a virus or bacterium was responsible?

4. Tell two ways in which either of these diseases (smallpox or measles) gives us insight into how humans and pathogens interact to influence each other. You may use examples from history or modern times.
