It's one of those opaque big-data efforts that compiles aggregate testing data from a proprietary panel that looks for the full range of respiratory viruses. We don't know what demographics are getting tested or where they are located. The company is based in Utah and - based on my own assessment of their reported SARS-CoV2 positivity rates - it would seem that their dataset correlates with overall infection trends in the western USA and particularly California.
Anyway, the percentage of their tests coming back positive for something has reached a new high. Respiratory syncytial virus (RSV) is having a big moment, parainfluenza is running high, adenoviral infections are higher than at any point in the past few years, and influenza is rising and anomalously high for this early in the season. SARS-CoV2 is fairly low relative to recent waves and is just beginning to rise again presumably reflecting seasonality and the new variants which are already driving waves in Europe and Asia finally becoming prevalent here.
What does this mean? Who knows really, and it's easy to over-interpret these trends, but it certainly does not appear that our collective immunity against respiratory infections is in good shape, and I can think of a few reasons why that might be true...
