The following images plot the number of new cases for 30 days,  The images are ordered from most recent to oldest.  Compare the trendlines of each graph to see how the 30 day trend of new cases is changing.  If you see the trend getting steeper in an upward direction from day to day, COVID is increasing in the county.

Remember the new cases today are the result of our behavior about two weeks ago.  If the trendlines are steadily getting steeper, the rate of COVID increase is probably greater than the trendlines indicate.
