Respiratory Adenovirus National Trends
Updated February 22, 2024
Participating laboratories report weekly to CDC the total number of adenovirus 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 graph below displays the average number of adenovirus tests that were performed nationally, 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 general, respiratory adenoviruses (untyped, as collected in NREVSS) do not typically demonstrate discernible seasonal circulation patterns. For type-specific respiratory adenovirus results visit the National Adenovirus Type Reporting System (NATRS).
