Students were sent home and three schools were closed when higher than normal amounts of Legionella, the bacteria that causes Legionnaires’ disease, were found in cooling towers.
The schools were located in the U-46 school district, located 45 miles northeast of Chicago. Officials found the high level of bacteria during an annual air quality check.
The district stated in an alert on their website: “While risk of exposure to the bacteria was low, we decided, in consultation with the Kane County Health Department, to evacuate staff and students to safe locations as a precaution.”
Reuters reported that the district was properly cleaning and sanitizing all 19 water cooling towers. So far, there have been no reports of anyone within the schools contracting Legionnaires’ disease.
Illinois has been concerned with the disease after 12 residents of a western Illinois veteran home died of Legionnaires’ last month. USA Today reports that dozens of home residents have contracted the disease. Legionnaires’ also infected 119 people and killed 12 in the New York City Outbreak earlier this year.
Legionnaires’ disease is a pneumonia-like disease that is caused by inhaling bacteria infected vapor. The vapor can come from air conditioners, showers, or hot tubs. The disease can lead to kidney failure, respiratory failure, and septic shock. Most people recover, but the CDC reports that 5% to 30% who contract the disease will die. It cannot be transmitted between people.
