How We Monitor Illness Activity
The Health Department monitors flu and COVID-19 activity and vaccine coverage in the state throughout the year. Timely data helps us understand how diseases are spreading. We collaborate with health care providers, laboratories, clinics, emergency departments, CDC, and other state health departments to track measures like:
- Emergency department visits for flu-like illness
- Emergency department visits among people with confirmed COVID-19
- Wastewater monitoring
- Flu subtype and strain testing
- Reported outbreaks
