Flu Interpretation
Why Do Flu Numbers and How People Feel Sometimes Disagree?
Both can be true. A CDC FluView number can be the right statewide surveillance signal and still feel different from what you hear locally, because ILINet measures a weekly outpatient sample, not every infection, school absence, workplace illness, or city-level cluster.
15-second answer
- CDC FluView / ILINet is a surveillance signal. It tracks the share of outpatient visits that look like flu-like illness, not every flu infection or every person staying home sick.
- The current national ILINet signal is low at 1.6% of outpatient visits for flu-like illness in the week ending May 23.
- Local experience can feel different because clinics, schools, workplaces, households, and cities can run hotter or cooler than the statewide sample.
- Weekly reporting lag also matters. The number can trail what people are noticing this week, especially when activity is turning or when a local pocket is busy.
Why this matters 1
This question comes up on winner flu pages when a statewide number looks lower than what someone is hearing from a school, clinic, or workplace.
Why this matters 2
A useful flu answer should protect both ideas: respect the source signal, and explain why it is not the same thing as a live city-level illness count.

This page should clarify source scope without turning anecdotal reports into a stronger signal than the CDC data. It is interpretation and routing, not medical advice.
FAQ
Quick questions about this answer
Does a lower state flu number mean nobody around me has flu?
No. It means the statewide outpatient surveillance signal is lower. Your city, school, workplace, or household can still have people sick, and ILINet is not a live count of every infection.
Should I trust the number or what people around me are saying?
Use them for different jobs. The number is better for broad trend and intensity. Local experience is a clue that your immediate setting may differ from the statewide average.
