    This state hasn't yet permitted us to use its CDC-reported ILI data.
    This state's DoH permitted us to use its CDC-reported ILI data, which leads to much more accurate nowcasting. We love you!
    This state's DoH doesn't yet post its ILI data online.
    This state's DoH posts its ILI data online, which leads to more accurate nowcasting. Thank you!
