Another mid-Michigan school is reporting students sick with the swine flu, or H1N1 virus.

The Linden Public School District told parents Friday that doctors diagnosed two Hyatt Elementary School students with the illness.

Monday a doctor diagnosed a Linden Middle School student, who is a sibling of one of the ill elementary school students.

Superintendent Ed Koledo says school will remain in session, and the buildings have been sanitized.

Students say teachers are drilling home the importance of hygiene in preventing the spread of the flu. 

Any student with flu symptoms is asked to stay home from school as the district works to prevent the spread of the illness.
