National U.S. map

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 most recent weeks, in particular the most recent two weeks, may be less complete than others. The trend graph below displays the weekly national average percent of diagnostic tests positive for RSV among all the diagnostics performed to detect RSV, as reported by participating laboratories. The RSV detection graphs below display the 5 week moving average (average of the 4 previous and current weeks) in accordance with the recommendations for assessing RSV trends by detections.
