The public health department and the state board of education say schools need to keep track of absences so they can spot signs of an outbreak. They're encouraging schools to isolate students and staff who show signs of the virus and send them home.
"I want to reassure parents, their teachers, and staff and students that the Illinois Department of Public Health and the Illinois State Board of Education are working together with local districts to protect the health of students and staff," said Dr. Damon Arnold, Illinois Department of Public Health.
The board of education says flu vaccinations will be offered at many schools. However, there won't be a formal statewide vaccination program.
