RSV State Trends

« Back to Respiratory Syncytial Virus (RSV) Surveillance

Participating laboratories report weekly to CDC the total number or RSV tests performed that week, and the number of those tests that were positive. Because reporting delays may be expected for some laboratories, data shown for the more recent weeks may be less complete than others. Each point on the trend graphs below displays the average number of RSV tests that were performed, and the average percent of those that were positive from three adjacent weeks: the specified week, and the weeks preceding and following it. This is also known as a centered 3-week moving average.

State-level trends are only displayed when two or more labs report RSV antigen testing data for at least 36 of the prior 52 weeks. If data for a state are too sparse to display during a particular week, we recommend viewing the trends at the HHS Region or Census Division level that contains the state of interest.

In the United States, RSV infections typically occur at the time of annual community outbreaks, during late fall, winter, and early spring. There may be variation in the timing of outbreaks between regions and between communities in the same region.
