24 Hour Rule

In addition to the CDC's guidance on keeping students who exhibit flu-like symptoms home at least 24 hours after they no longer have a fever or signs of fever, Katy ISD Administrative Regulation FFAD is in place to ensure the health and safety of all students and states that students who exhibit vomiting, diarrhea, or a fever greater than 100.4, must be excluded from school. Re-admittance is allowable as follows:

  • Child's temperature less than 100.4 for at least 24 hours without the use of fever-reducing medications such as acetaminophen or ibuprofen. Common trade names of products containing these medications include, but are not limited to Tylenol, Motrin, and Advil. All aspirin-containing products should be avoided.
  • Food and liquids have been tolerated for at least 24 hours without vomiting and/or diarrhea, and without the use of medication to relieve symptoms.
  • Students diagnosed with a contagious illness that is being treated with prescription medication, must complete a minimum of 24 hours of the prescribed dosage prior to returning to school.

Please be aware that a doctor's note does not supersede the 24 hour rule.
