Questions -
Question 1 - 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 2 - Look at the lower graph in Figure 6-1. This represents the cumulative number of AIDS cases and deaths to date for the given year.
Approximately how many patients had been diagnosed with AIDS in the USA by the year 2010?
What fraction of these patients had died by the end of 1998?
What fraction of these patients had died by the end of 2010?
1,000,000; 1/2; 7/8
1,000,000; 1/3; 2/3
1,200,000; 1/3; 1/2
1,200,000; 1/2; 2/3
Question 3 - 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 4 - 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?
Question 5 - According to the epidemiology data presented in Chapter 6, what sexual practice has been shown to be associated with the highest risk of HIV transmission?
