Here is another movie generated by my Kinsa fever data display program.
This video uses color to show which US counties have similar Kinsa fever thermometer statistics. This particular video colors counties with recent (previous 15 days) higher-than-other-county-fever-percentages in red tones, less recent high percentages in green tones, and high percentages older than 45 days in blue.
Watch red to see how fever moves around the country over time. Watch for blue to see counties that have had fever, but not for a while. Green counties were feverish around a month before the end date.
During the video, the end date runs from mid-March to August 7th.
