Communicable Disease in Schools

  • The Centers for Disease Control and Prevention (CDC) have identified some communicable diseases that health care providers, including nurses, must report to the state or local health department.
  • Due to the immediate threat posed by some diseases, the diseases listed that are to be immediately reported (within three hours) and those to be reported within 24 hours should be reported by school nurses within those time frames as soon as notified by a parent or the student's health care provider that the disease is present or suspected.
  • Any schools located in Chicago MUST report to any of these reportable conditions to CDPH
    • If your school is not located in Chicago, please report to your local health authority.
  • Please review all the IDPH requirements for communicable disease reporting
