Reflect: Epidemiology
The prevalence rate of tuberculosis in one particular county in Texas is 7/1000 people, while the incidence rate for
2011 is 2/1000 people. Analyze this data and summarize the situation.
Incidence rate should really be higher than prevalence rate because it includes all new cases for the year.
The data were collected incorrectly because the two values should match.
Prevalence rate is higher than incidence rate because the number of people still alive with tuberculosis is higher because of
better treatments.
Prevalence rate and incidence rate cannot be determined for the same disease.
The number of new cases of a disease in a population over a specific period of time compared with the healthy
population is the ______.
incidence rate
prevalence rate
epidemic rate
mortality rate
morbidity rate
