Call it "Bronco-itis" or "The Orange Flu" or "Blue Pneumonia". More than a quarter of all Denver Public Schools students were out sick on Tuesday, the day of the Broncos Super Bowl victory parade and rally.

According to 9 News:

Of the 90,000 students who attend early childhood education through high school at DPS, 24,152 were out for one class period or more Tuesday...And that's not counting the Northern Colorado kids.

Attendance on Wednesday seemed to be back to normal.
