COMMUNICABLE DISEASES
Epidemiologists collect and analyze data to help keep our communities healthy and to reduce the spread of communicable diseases. They work closely with healthcare providers. The process of monitoring a reportable disease begins with a patient seeking care. Once a patient is tested and receives a positive result, the healthcare provider informs the local public health department. We then contact the patient to provide education, guidance, and resources to help slow or stop the spread of the disease.
Case numbers are monitored by our epidemiologists to detect outbreaks, clusters, and trends.

Understanding the Incident Rate
The numbers in the 2024 Rate and 2025 Rate columns represent the incidence rate for each disease.
- Definition: Incidence is the measure of new cases of a disease that occur in a specific population over a defined period (in this case, one year).
- The Calculation: This is expressed as the number of cases per 100,000 people.
