Covid Symptoms in Children: What to Watch For

In children, covid usually looks like an ordinary respiratory illness. The American Academy of Pediatrics lists cough, sore throat, headache and fever as the most common symptoms, followed by chills, shivering, runny nose, muscle pain, fatigue, and loss of smell or taste. Most children have a mild illness and recover quickly, and pediatric deaths are rare — but the warning signs for the minority who get worse are specific and worth memorizing.

The symptoms parents actually see

Most common: cough, sore throat, headache, fever.

Also common: chills, shivering or shaking, runny nose, muscle pain, fatigue, loss of smell or taste.

Less common: nausea, vomiting, diarrhea.

In some children: progression to shortness of breath.

A note on that last group. Digestive symptoms are frequently described as a distinctly pediatric feature of covid, and it is worth being precise: the AAP lists nausea, vomiting and diarrhea among the less-common symptoms in children, not as a hallmark. They happen, they can appear without any cough or congestion, and they are not by themselves a reason to assume covid over the many other things that upset a child’s stomach.

How soon symptoms start

The AAP puts the average incubation period at 3 to 5 days after contact with the secretions of someone who has covid, with a range of 2 to 14 days, and notes that incubation can vary by variant. MedlinePlus gives the same 2-to-14-day window for the general population, most often around day 5.

Call 911 now

The AAP’s emergency triggers are short and unambiguous:

• Severe trouble breathing — struggling for each breath, able to barely speak
• Lips or face are bluish now
• Any situation you believe is a life-threatening emergency

Call the doctor the same day

Contact the pediatrician right away — not tomorrow — if your child has:

• Moderate difficulty breathing, or breathing much faster than usual
• Ribs pulling in with each breath (retractions)
• Wheezing, or a harsh noisy breath in (stridor)
• Chest pain that prevents a deep breath
• Severe sore throat or severe muscle pain
• Signs of dehydration — few wet diapers, no tears, dry mouth, refusing fluids
• Fever above 104°F (40°C)
• A weakened immune system or another high-risk condition
• A child who simply looks very sick to you

That last one is not filler. Parents notice deterioration before a symptom checklist does.

Home care for a mild case

Most children ride this out at home. AAP guidance:

1. Fluids first. Dehydration is the complication that most often turns a manageable illness into a visit.
2. Treat fever for comfort, using acetaminophen or ibuprofen for fevers above 102°F (38.9°C). Never give ibuprofen to an infant under 6 months without a doctor’s direction, and never give aspirin to a child.
3. Honey for cough, but only for children age 1 and older — honey is unsafe for infants under 12 months.
4. Heat for muscle aches.
5. Rest, and let them set the pace.
6. Stay home until fever has been gone for 24 hours without fever-reducing medicine and symptoms are improving, then keep away from vulnerable people for a further period.

Covid, cold or flu

You cannot tell them apart from the symptoms in a child any more reliably than in an adult — the lists overlap almost entirely. Testing is what separates them, and it matters most when someone at higher risk lives in the house or when antiviral eligibility is on the table. For the adult picture and the full severity ladder, see covid symptoms.

Smell and taste in kids

Loss of smell or taste is on the AAP list, but it has become a much weaker clue than it was early in the pandemic, and children are less likely than adults to report it clearly in the first place. The measured decline across variants, and the many other causes, are covered in loss of taste and smell causes.

When symptoms outlast the illness

If fatigue, headache, trouble concentrating or breathlessness are still there months after the infection, that has a formal definition that explicitly includes children — see long covid symptoms.
