How to use this data
The RSV, COVID-19, and influenza charts display how viral activity for three of the most severe respiratory illnesses has changed over time. Some datasets allow you to explore trends by age group and location (state or county). The map slider lets you see how activity shifts week by week across regions.
The time series plots show the weekly intensity of each virus, with data standardized on a scale from 0 to 100 to make trends easier to compare across different sources. To improve clarity, the data are smoothed using a 3-week average. In some cases, data may be missing due to privacy protections; when noted, small placeholder values are used in the plots to maintain visual continuity.
Emergency department visits by state
Proportion of ED visits caused by RSV. Some states have county-level data available, while others have state-level data only. By moving the slider, you can see how the virus moves across the US each season.
