a. During which stages of an infectious disease does the host exhibit signs and symptoms? Is there a
correlation between this and when a disease is communicable?
b. Why are some viral diseases, like smallpox and polio, no longer seen in the United States? Why are
many bacterial disease, like syphilis, no longer a death sentence? Think about how these two types
of microbes infect humans. Why might we make an effort to treat viral diseases before infection but
continue to treat bacterial diseases after infection?
c. Based on the graph below, which pathogen is more virulent: Agent 1 or Agent 2? Explain.
