Respiratory Illness Dashboard

Key Takeaways for the Week of September 10, 2026

• COVID-19, flu, and RSV are very low based on emergency department data. 
• The Wisconsin State Laboratory of Hygiene is currently upgrading its testing methods, temporarily pausing wastewater data updates. This means the Madison and Oregon wastewater sites have not yet received new data for September.

This dashboard is updated on Thursdays at 12:30 pm. If the dashboard is not updated then, we may be experiencing technical issues; check back at 4:30 pm. If we experience a delay in receiving data from one of our data sources, that data element will be updated the following week.
