Epidemiology & Surveillance

Epidemiology is the study of how often diseases or other health outcomes occur in a community and who is affected by them--with the ultimate goal of learning the most appropriate strategies for prevention of the disease. 


The word “surveillance” in public health relates to the process that is used to identify, report, and count cases of disease.   Information collected and presented by epidemiologists help public health officials prioritize health concerns and plan accordingly for their community.   See below for information on local infectious disease surveillance data.
