Respiratory Illness Dashboard

Key Takeaways for the Week of June 4, 2026

  • COVID-19, flu, and RSV are very low, based on emergency department data.
  • The percent of positive lab tests for rhinovirus and enterovirus, which cause the common cold, has started to decrease, but remains higher than normal. There's been an uptick in the percent of positive lab tests for parainfluenza in the last several weeks. This is important for babies, as it is a leading cause of croup and bronchiolitis. 
  • Based on air sampling data from schools in Dane County, there seems to be elevated COVID-19 activity in the last few weeks, particularly amongst middle and high schoolers.
