Your zipcode map doesn't convey much information when the entire map is red.
Change the color ranges. The first four colors cover only <=200 cases. There's no way to determine zipcodes that are hardest hit without going through dozens of red ones. There are at least 2 zips over 2k now. Legend should be more like:
Greater than 2500
This legend will work for the next 6 wks hopefully. Then you will have to update again.
