CDC shows only the current week, so last week comes from our own saved weekly history, which starts the first week we saw the data. "New" means that history has no level for that place last week. "No data" means CDC reported no data for it.

Find your state in the table above to see the level the Centers for Disease Control and Prevention reports for the most recent week. The key facts at the top count how many places fall at each level.

## What the level measures

The agency rates each state with a measure it calls acute respiratory illness. In its description of the data, the agency says the measure "captures a broad range of diagnoses from emergency department visits for respiratory illnesses, from the common cold to severe infections like influenza, RSV and COVID-19." The level therefore describes all of those illnesses together and is not a count of flu cases alone.

## How to read the table

The first column of levels is the most recent week the agency has published, and the date of that week is in the line under the key facts. "No data" means the agency reported no level for that place for the week.

The agency publishes only the current week, so the comparison with last week comes from the record this page keeps of each weekly release. Where that record has no level for a place for the week before, the table says "not in our history" and gives the direction as "new".

## When it updates

The agency says the data are updated once a week, on Fridays. This page is updated at the same address after each release.

## What this page is not

This page reports public health data and is not medical advice. The level for a state does not say whether any one person is ill or what that person should do, and questions about symptoms belong with a doctor or a local health department.
