BATAVIA – School officials in Batavia say they’ve found traces of the bacteria that can cause Legionnaires’ disease in the northern Illinois community’s schools.

WNIJ Radio reported that the school district has notified parents that a water analysis detected the Legionella bacteria. The contamination was found at Alice Gustafson Elementary School, Batavia High School and Hoover-Wood Elementary School.

Such bacteria are commonly found in water and water fixtures but can cause Legionnaires’ disease in people with weak immune systems. So far, no illnesses have been reported in Batavia.
