Probably a confluence of factors are at work besides the pattern of waves and lulls . The people most likely to get infected (zero precautions, frequent exposure) have probably been infected by now. Those most likely to run to be tested as well as those most likely to become seriously ill have mostly begun or completed the vaccination process. These, along with the available treatments to prevent progression to serious illness are likely the driving factor behind the low numbers and really low hospitalizations. Hopefully things continue to trend this way going forward......
