Analyzing Disease Frequency
Assessment Brief
Analyzing Disease
Frequency
(500 words minimum)When
epidemiologists measure disease frequency, they analyze the incidence and
prevalence of a disease. Incidence is the number of new cases of a disease in a
particular population during a specific time period. This measure is useful when
public health officials and epidemiologists are looking at the first occurrence
of a disease. It is also important when comparing populations to determine
disease risk.
For
each problem, answer the following questions:
Name the appropriate measure of disease frequency
that should be used in each scenario and justify its use (why that particular
measure is the appropriate one).
