of outpatient visits for flu-like illness
Week ending Aug 22, 2026
Yes, flu is still going around in Wisconsin, but the latest CDC ILINet signal is low: 0.4% of outpatient visits were for flu-like illness for the week ending Aug 22, 2026, and the trend is stable (similar to 0.3% last week).
Season context: 0.4% is down from 3.8% at the season peak for the week ending Dec 27, 2025.
Stable trend: Stable means the CDC ILINet share is roughly unchanged from last week; pair it with the current low level and week-ending date instead of reading it as an all-clear.
If this statewide CDC number does not match what people around you are feeling,read why flu surveillance and local experience can differ.

Where does this flu data come from?
This data comes from the CDC's ILINet (Influenza-like Illness Surveillance Network), accessed via the Delphi Epidata API. ILINet includes reports from thousands of healthcare providers in participating states who track the percentage of patient visits for flu-like symptoms each week.
How often is this page updated?
This page is updated weekly, typically on Fridays after the CDC publishes new FluView data. The data usually reflects activity from the previous week, so there is a one-to-two week delay between when illness occurs and when it appears here.
