a. To eradicate a disease before it starts
b. To establish a baseline rate of disease oc-currence and patterns of spread
c. To target populations for triage
d. To reduce the incidence of heart disease in a community
ANS: B
Disease surveillance helps establish baseline rates of disease occurrence and patterns of spread to make it possible to initiate a rapid response to an outbreak. Disease surveillance is unable to erad-icate a disease before it starts, to target populations for triage, or to reduce the incidence of heart disease in a community. However, disease surveillance does make it possible to initiate a rapid response to an outbreak of a disease or an event that can cause a health problem.
