Question 1
Epidemiologists gather a lot of information from patients about what they have been doing in their lives in order to get clues about their illness, how they caught it, how it spreads, what type of interactions with people put other people at risk, etc. They compile the information and use it to determine the risks associated with different behaviors.
Can epidemiology predict the likelihood that you, as an individual, will become infected at some point in your life? Explain your answer.

Explain how the presence of different subgroups and clades of the HIV can make it easier for epidemiologists to track the route of transmission of the virus, while at the same time, complicate the detection of the virus in patients.

Question 6 10 pts
Look at Figure 6-1. The graph on the top half of the figure shows the total number of new AIDS cases in each year, as well as the total number of deaths during that year. According to the graph, how has the incidence rate and death rate of AIDS changed since 2000. Choose the best answer:
The death rate has increased, while the incidence rate has decreased.
Both the death rate and the incidence rate have remained the same.
Both the death rate and the incidence rate have increased slightly.
Both the death rate and the incidence rate have decreased slightly.

Question 9 10 pts
Look at Figure 6-4. Epidemiology has allowed us to track changes in disease patterns over time. Discuss:
1. Which risk group in the USA was most impacted by the AIDS epidemic as of 1986,
2. How had this changed by 2010?
3. Can you explain any of these differences in terms of the historical events or other changes in society between 1986 and 2010?
