DENVER — Health officials are investigating after between 25 and 30 students at a southwest Denver middle school got hives Wednesday.
Denver Public Schools spokesperson Will Jones said the students attend DSST: Henry Middle School in the Bear Valley neighborhood.
Most of the students are in eighth grade.
All after-school activities were canceled Wednesday.
The school nurse asked some of the affected students to stay home Thursday, Jones said.
It’s unknown what caused the outbreak.
