Children do not need to be completely symptom-free to return to school or child care. In general, they should be well enough to participate and should not need more care than staff can safely provide. Always follow the program’s written rules and any local public-health guidance, which can be more specific during an outbreak.

Urgent Warning Signs - Check This First

CALL 911 NOW

  • Severe trouble breathing, blue or gray lips or face, a seizure, a child who is limp or unresponsive, a rapidly spreading purple or bruise-like rash, or another life-threatening emergency.

  • A child has immediate danger to self or others.

GET EMERGENCY MEDICAL CARE NOW

  • A baby younger than 3 months (12 weeks) with a rectal temperature of 100.4 F (38 C) or higher.

  • A child who looks very ill, has significant dehydration, severe pain, a stiff neck, difficulty breathing, or cannot stay awake normally.

CONTACT YOUR CHILD'S HEALTHCARE PROFESSIONAL TODAY

  • Fever with a new rash, bloody diarrhea, repeated vomiting, a child who is worsening instead of improving, or a concern that needs an individualized return-to-school plan.

  • A positive test, known exposure, or a diagnosis such as measles, chickenpox, pertussis, Shigella, or another condition for which a health department, school, or child care program may have specific exclusion requirements.

The Main Return-to-Participation Question

  • Can the child take part in normal activities, including eating, drinking, using the bathroom, and managing improving cough or congestion without needing continuous one-on-one care?

  • Will the child’s symptoms make it difficult for staff to teach, supervise, or safely care for other children?

  • Does the child have a symptom or diagnosis that creates a meaningful risk of spreading infection under the school or program’s policy?

If the answer to any of these is no or uncertain, keep the child home and ask the program or healthcare professional what is needed for return.

Common Reasons to Stay Home

  • Fever, especially fever with a new rash or other symptoms. In general, return after the child has been fever-free for at least 24 hours without fever-reducing medicine and is well enough to participate, unless the program or clinician gives different instructions.

  • Vomiting that has not resolved, or a child who cannot hold down fluids or food in the morning.

  • Diarrhea causing accidents, blood in stool, or stool frequency clearly above the child’s usual pattern.

  • Respiratory symptoms that are worsening or not improving, or a cough/congestion pattern that prevents ordinary participation.

  • Draining skin sores that cannot be covered, a rapidly spreading rash, or an illness that needs specific assessment or treatment before return.

When a Child May Often Return

  • An improving cough or runny nose without fever may not require exclusion if the child can participate. Yellow or green nasal mucus alone does not decide whether a child must stay home.

  • A child may return after respiratory symptoms have been improving overall for at least 24 hours, is fever-free for at least 24 hours without fever-reducing medicine, and can manage symptoms at school or child care. Additional measures to reduce spread may be helpful when advised by the program or public-health authorities.

  • After vomiting, return when vomiting has resolved overnight and the child can hold down food and liquids in the morning.

  • After diarrhea, return when stool has improved, accidents have stopped, and the child can participate. Bloody diarrhea needs medical evaluation before return.

Specific Diagnoses Need Specific Instructions

  • ·Some infections have their own return criteria. Examples can include strep throat, influenza, COVID-19, chickenpox, measles, pertussis, certain diarrheal infections, and skin infections. Do not rely on a general rule if the child has a confirmed diagnosis.

  • The program, school nurse, healthcare professional, local health department, or all of these may give instructions. Ask whether a note, treatment interval, test result, or health-department clearance is required.

  • Antibiotics do not automatically make a child ready to return. The child must also be well enough to participate and meet the program’s requirements.

Preparing for a Smooth Return

  • Read the school or child care illness policy before the first illness. Save the nurse, director, and health office contact information.

  • Tell the program about allergies, asthma, diabetes, seizures, food restrictions, and medicines that may be needed during the day. Keep action plans and medication forms current.

  • Make sure the program has current emergency contacts and knows who may pick up the child.

  • When the child returns, send only medicines or supplies that have been approved through the program’s established process. Never send a child with medicine in a backpack unless the program has specifically authorized it.

Helping Reduce Spread

  • Teach handwashing with soap and water, covering coughs and sneezes, and not sharing drinks, utensils, or lip products.

  • Keep recommended vaccines current. Clean high-touch items and ensure the child has tissues and a water bottle when appropriate.

  • Respect the privacy of other families. Do not assume you know a child’s diagnosis based on a symptom or absence.
