One current respiratory check
Flu-like illness, RSV, and COVID-19 are all tracked below for the latest national source week. Start with direction and activity level, then open the metric note before comparing anything.
Latest source week: week ending Sep 26, 2026
15-second answer
Updated from checked-in source data Oct 3, 2026
Flu-like illness
1.7%
→ Stable — relatively steady across the latest three weekly reports
A symptom-based outpatient signal. ILI can include flu, COVID-19, RSV, or other respiratory illnesses.
RSV hospital admissions
0.1 per 100K
→ Stable — relatively steady across the latest three weekly reports
A hospital-burden signal. It does not count every RSV infection in the community.
COVID-19 hospital admissions
1.3 per 100K
→ Stable — relatively steady across the latest three weekly reports
A hospital-burden signal. It does not estimate every COVID-19 infection in the community.
Do not compare unlike numbers
The flu card uses outpatient visits for influenza-like illness. The RSV and COVID-19 cards use hospital admissions per 100,000 people. A higher raw flu percentage does not mean flu is “more common” than the other viruses. Compare each series with its own recent history, and use the source date and scope before sharing a conclusion.
Why health sources can disagree →Make it local
National signals are orientation, not a local answer. Search a real place to open its overview or switch directly to flu, RSV, or COVID-19.
Verify and reuse
The files include the full checked-in national time series for each signal, plus metric, unit, activity label, official source name, and official source URL. They update with the site’s weekly data refresh.

Read the scope before the number
The latest national source week ends Sep 26, 2026. Flu-like illness, RSV hospital admissions, and COVID-19 hospital admissions are all shown above with their current activity label and direction. These signals describe different parts of respiratory illness, so use a state or city page for the local picture.
No. Flu is the percentage of outpatient visits for influenza-like illness, while RSV and COVID-19 are new hospital admissions per 100,000 people. Compare each signal with its own recent trend and activity label, not with the raw magnitude of another metric.
No. Low is a surveillance activity label, not zero illness. These weekly systems also have reporting lag and do not count every infection, so they are best for orientation and trend checks rather than diagnosis or clinical decisions.
