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.
Is flu getting better or worse in Tennessee?
Based on the CDC's reproduction number (Rt) estimate, flu in Tennessee is growing with an Rt of 1.12. This means each flu case may be generating more than one new case, so activity could increase. There is a 100% probability that flu is growing.
