learned about the pathology of the disease.
6 What does an epidemiologist mean when he or she refers to a "Chinese menu" case definition.
7 What are some of the benefits derived from applying a uniform case definition
for
a vague syndrome like Chronic Fatigue Syndrome.
8 Do you think Major Criteria #2 for for Chronic Fatigue Syndrome as
described in Table 5.1, p. 114 ("other conditions that produce similar
symptoms excluded") was included in order to increase the specificity or
sensitivity of the case definition?
9 Discuss how the AIDS case definition has evolved over time.

1 List factors that may cause an artifactual
increase or decrease in reported rates of disease.
2 List factors that may cause an artifactual increase or decrease in the
