RSV Census Division Trends

« Back to Respiratory Syncytial Virus (RSV) Surveillance

Participating laboratories report weekly to CDC the total number of 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.

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.
