Flu virus

It appears that we have a virus working it's way around the school.  Several students have been sick with low fevers and coughs.  The fever seems to just last about 24 hours, but the cough has been lingering.  If if your child has a fever of over 100 degrees please keep them home.  They need to be fever-free for at least 24 hours before returning to school.  I don't want to alarm you and it doesn't seem to severe or last very long.  Just thought I would pass the information along to you.
