Notes

  1. A number of states have discontinued reporting COVID data on a daily basis. Therefore, many state charts may show the most recent date with zero tests. This daily test number is represented on each chart as the number next to the end data point for each state’s respective data line.

  2. The median line represents the median of the most recent seven-day average of daily testing reported by all states. Taking a median of only the most recent date when many states no longer report daily numbers would provide a highly distorted value for a median.
