After an acute and seemingly widespread case of Ravens Fever afflicted many students early this week, attendance at Baltimore County Public Schools was back to normal on Wednesday, school officials said.

Charles Herndon, a spokesman for Baltimore County Public Schools, said 94.9-percent of the county’s 107,033 students were in school on Wednesday, the closest to the January average of 93.5-percent as attendance has been since the Ravens’ Super Bowl victory on Sunday.

Herndon said just 83.5-percent of students were in school on Tuesday, meaning around 18,000 students were absent.

Officials estimate over 200,000 people filled M&T Bank Stadium and lined the streets of Baltimore on Tuesday for a celebration of the Ravens’ 34-31 win over San Francisco in Super Bowl XLVII.

“While that may not seem like a lot, keep in mind we have more than 107,000 students, so a drop of 10-percent or so is a lot of students,” Herndon said in an email.

On Monday, the day after the Super Bowl, Herndon said attendance countywide was 89.8 percent, meaning over 10,000 students were absent.

"It appears Ravens Fever has run its course...for this year," Herndon said.
