A fast time lapse map of coronavirus active cases in the United States. By county and per capita.

  1) Colors are like a traffic light. Green, yellow, red... but then violet, purple, blue for even higher infection rates.   

  2) Colors represent number of active cases proportional to a county's population (per capita). This is only active cases (new cases in the past two weeks) and is not total cases in a county. This is different than other maps which tend to show total cases since the beginning of the epidemic.
