Multiple students and staff members in a Wisconsin school district were sickened by a mysterious illness, according to the Forest County Sheriff’s Department.

In a March 14 news release, the Sheriff’s Department wrote that three students and five staff members at Crandon Elementary, Middle, and High Schools became ill with the mysterious illness.

In a letter to the school community, the superintendent of the Crandon School District wrote that the cause was not clear.

However, in a later update, the Forest County Sheriff’s Department revealed the cause, writing:

On March 14, 2024 the Crandon School District Building was evacuated. The Oneida County HazMat and Wausau HazMat Teams were requested by the Forest County Sheriff’s Office to assist. Oneida and Wausau Hazmat determined it was a mechanical issue with the furnace that created elevated levels of Carbon Monoxide inside the school.

Area hospitals were contacted and it was reported 39 patients received medical attention related to this event at the Crandon School. Of the 39 patients, two had reported elevated levels of Carbon Monoxide.

Classes and school events for the Crandon School District have been cancelled for today. The School District reports it is making an active effort to make the school safe and rectify the situation to open campus for classes. See the Crandon School District website for information when classes will resume.

This afternoon, at approximately 1:00 p.m., we began to receive reports that a few of our students were experiencing shortness of breath, light-headedness and increased pulse rate. As the day progressed, several staff members also reported these symptoms. In response to these concerns, we made the decision to evacuate the building and sought assistance from the Sheriff’s Department to help us determine the cause of these symptoms.

Despite our best efforts, we were unable to identify a specific cause. With the safety of our students and staff as our top priority, we made the difficult decision to cancel school for the remainder of the day.

We have law enforcement and other relevant authorities remaining on-site as we continue our investigation into the cause of today’s events. At this time, the investigation remains ongoing, and as a precaution, we have decided to cancel school tomorrow, Friday March 15, 2024 as well as all after school events tonight and tomorrow.
