Respiratory Illness Dashboard

Key Takeaways for the Week of April 10, 2025

• The number of people in the ER with COVID, flu, RSV, and all respiratory illnesses are all at low and stable levels.
• ER visits for respiratory related illnesses are still elevated in the 0-4 population. About 30% of kids under 4 years old were diagnosed with a respiratory illness in the ER.
• The percentage of people testing positive for parainfluenza continues to increase. Parainfluenza is a virus that causes colds and respiratory infections, especially in young children, older adults, and people with weak immune systems.
• The school district we share school absence data from had spring break last week, March 31st-April 4th, so there is no new data for that page this week.
