Key Takeaways for the Week of January 15, 2026
- We are working to update our thresholds under the weekly summary part of the landing page, in the meanwhile we've directly applied DHS' thresholds to the more current data presented on our dashboard.
- Based on emergency department data, flu continues to spread and is at a moderate level, impacting kids aged 17 and under the most.
- In the past two weeks there have been many detections showing COVID-19 is increasing in wastewater in Madison and Oregon. Both the number of people diagnosed with COVID-19 and the percentage of positive COVID-19 lab tests have also steadily increased in that same time. Last week, over half of air samples from schools within Dane County were positive for COVID-19.
- Among kids in the emergency department last week, nearly 40% under 4 and just under 20% aged 5 to 17 were diagnosed with a respiratory illness.
