For now, the health department is working with school officials to encourage habits to ward off the virus.
"Though they (the schools) usually put these things into place before we even get to them," she said.
That means encouraging hand washing, especially after bathroom visits, and roping off water fountains where kids are likely to spread germs.
"Especially the elementary kids, it's hard for them to keep their mouths off the different parts of the fountain like you're supposed to," Isaac said. "We cover those up and go with paper cups."
Parents are also being encouraged to keep their kids away from school if they're not feeling well, and to make sure they are completely well before they send them back to school. Generally, Isaac said, students should be symptom free for at least 24 hours before they return to school.
"I appreciate that parents want the child to come back to school and we do, too," Isaac said.
"But their resistance is down and we don't want them getting sick again, so they need to stay home."
