Module Objective 1: Identify the unique challenges microbes face in invading and surviving in, as well as transmitting from, each mucosal tract.

1. Connect past and present: How long are respiratory pathogens likely to survive outside the body: minutes, days, or weeks/months? Why?
2. Connect past and present: Are respiratory diseases in general likely to be serious/fatal in healthy individuals? Explain.

Module Objective 2: Describe how human social structures play a role in key human diseases--pneumonia, TB, flu, fecal/oral diseases generally, sexually transmitted diseases generally-and major public health interventions for preventing them.

1. What does the USSR experience with diphtheria tell us about the relationship between public health and individual illness?
2. What is DOT and why is it the "gold standard?"
3. How were the developments of the 1918, H5N1 and 2009 H1N1 flus each influenced by human behavior? (And what is each?)

Module Objective3: Identify the broad taxonomic class, genus/species names, symptoms, transmission modes, major virulence factors (where specified) and at-risk populations of major respiratory, digestive and genitourinary tract diseases.

1. Describe four virulence factors that make GAS especially dangerous.  Describe one for diphtheria.
2. Why do you think we distinguish HA- from CA-pneumonia, even though HA- and CA- can both be caused by many different and overlapping organisms?
