When to keep your child home sick from school (and when they can go back)

Quick answer: As a general rule, the AAP says to keep kids home if they've had a fever above 101°F in the past 24 hours, vomiting or diarrhea in the past 24 hours, or aren't well enough to take part in class. CDC school guidance says they can usually return once they've had no fever for 24 hours without fever-reducing medicine and are getting better overall. Your school's policy comes first.

Steps

  1. Find your school's illness policy now, in the handbook or on the nurse's page. Fever cutoffs and return rules vary by district, so use your school's numbers when they differ.
  2. On a sick morning, ask three questions: Fever above 101°F in the past 24 hours? Vomiting or diarrhea in the past 24 hours? Well enough to join in class? A yes to any of them means a home day.
  3. Just a leftover runny nose or a slight headache? The AAP says that, depending on local attendance policy, kids can go to school if none of the three apply. Make sure the school can reach you during the day.
  4. Going back: wait until there's been no fever for at least 24 hours without fever-reducing medicine and symptoms are getting better overall.
  5. Report the absence the way your school asks (attendance line, app or email) and ask how to get any missed work.
  6. Line up a backup caregiver before cold and flu season peaks.
  7. Call your pediatrician with questions. For emergency warning signs such as trouble breathing or chest pain, get emergency care right away.

What CDC tells schools

  • Stay home with: a fever (including a fever with a new rash); vomiting more than twice in the past 24 hours; diarrhea that causes accidents, is bloody, or means more than two extra bowel movements in 24 hours; draining skin sores that can't be covered; or respiratory symptoms that are getting worse or not improving.
  • In general, CDC says children with improving symptoms should be able to take part in school.
  • CDC also asks schools to think carefully before requiring a doctor's note for illness absences, since many common childhood illnesses can be managed at home.
