Viral Upper Respiratory Illness (Child)

Your child has a viral upper respiratory illness (URI). This is also called a common cold. The virus is contagious during the first few days. It's spread through the air by coughing or sneezing, or by direct contact. This means by touching your sick child then touching your own eyes, nose, or mouth. Washing your hands often will lower the risk of spreading the virus. Most viral illnesses go away within 7 to 14 days with rest and simple home care. But they may sometimes last up to 4 weeks. Antibiotics will not kill a virus. They are generally not prescribed for this condition.

Home care

  • Fluids. Fever increases the amount of water lost from the body. Encourage your child to drink lots of fluids to loosen lung secretions and make it easier to breathe. 

    • For babies under 1 year old, continue regular formula feedings or breastfeeding. Between feedings, give oral rehydration solution. This is available from drugstores and grocery stores without a prescription.

    • For children over 1 year old, give plenty of fluids, such as water, juice, gelatin water, soda without caffeine, ginger ale, lemonade, or ice pops.

  • Eating. If your child doesn't want to eat solid foods, it's OK for a few days, as long as they drink lots of fluid.

  • Rest. Keep children with fever at home resting or playing quietly until the fever is gone. Encourage frequent naps. Your child may return to daycare or school when the fever is gone and they are eating well, does not tire easily, and is feeling better.

  • Sleep. Periods of sleeplessness and irritability are common.

    • Children 1 year and older: Have your child sleep in a slightly upright position. This is to help make breathing easier. If possible, raise the head of the bed slightly. Or raise your older child’s head and upper body up with extra pillows. Talk with your healthcare provider about how far to raise your child's head.

    • Babies younger than 12 months: Never use pillows or put your baby to sleep on their stomach or side. Babies younger than 12 months should sleep on a flat surface on their back. Don't use car seats, strollers, swings, baby carriers, and baby slings for sleep. If your baby falls asleep in one of these, move them to a flat, firm surface as soon as you can.


  • Cough. Coughing is a normal part of this illness. A cool mist humidifier at the bedside may help. Clean the humidifier every day to prevent mold. Over-the-counter cough and cold medicines don't help any better than syrup with no medicine in it. They also can cause serious side effects, especially in babies under 2 years of age. Don't give OTC cough or cold medicines to children under 6 years unless your healthcare provider has specifically advised you to do so.

    • Keep your child away from cigarette smoke. It can make the cough worse. Don't let anyone smoke in your house or car.

  • Nasal congestion. Suction the nose of babies with a bulb syringe. You may put 2 to 3 drops of saltwater (saline) nose drops in each nostril before suctioning. This helps thin and remove secretions. Saline nose drops are available without a prescription. You can also use 1/4 teaspoon of table salt dissolved in 1 cup of water.

  • Fever. Use children’s acetaminophen for fever, fussiness, or discomfort, unless another medicine was prescribed. In babies over 6 months of age, you may use children’s ibuprofen or acetaminophen. If your child has chronic liver or kidney disease, talk with your child's healthcare provider before using these medicines. Also talk with the provider if your child has had a stomach ulcer or digestive bleeding. Never give aspirin to anyone younger than 18 years of age who is ill with a viral infection or fever. It may cause severe liver or brain damage.

  • Preventing spread. Washing your hands before and after touching your sick child will help prevent a new infection. It will also help prevent the spread of this viral illness to yourself and other children. In an age-appropriate manner, teach your children when, how, and why to wash their hands. Role model correct handwashing. Encourage adults in your home to wash hands often.

Follow-up care

Follow up with your healthcare provider, or as advised.

When to seek medical advice

For a usually healthy child, call your child's healthcare provider right away if any of these occur:

  • A fever (see Fever and children, below)

  • Earache, sinus pain, stiff or painful neck, headache, repeated diarrhea, or vomiting.

  • Unusual fussiness.

  • A new rash appears.

  • Your child is dehydrated, with one or more of these symptoms:

    • No tears when crying.

    • “Sunken” eyes or a dry mouth.

    • No wet diapers for 8 hours in infants.

    • Reduced urine output in older children.

  • Your child has new symptoms or you are worried or confused by your child's condition.

Call 911

Call 911 if any of these occur:

  • Increased wheezing or difficulty breathing

  • Blue, purple, or gray color or tint to the lips or fingernails

  • Unusual drowsiness or confusion

  • Unresponsive or trouble awakening

  • Fast breathing:

    • Birth to 6 weeks: over 60 breaths per minute

    • 6 weeks to 2 years: over 45 breaths per minute

    • 3 to 6 years: over 35 breaths per minute

    • 7 to 10 years: over 30 breaths per minute

    • Older than 10 years: over 25 breaths per minute

Fever and children

Use a digital thermometer to check your child’s temperature. Don’t use a mercury thermometer. There are different kinds and uses of digital thermometers. They include:

  • Rectal. For children younger than 3 years, a rectal temperature is the most accurate.

  • Forehead (temporal). This works for children age 3 months and older. If a child under 3 months old has signs of illness, this can be used for a first pass. The provider may want to confirm with a rectal temperature.

  • Ear (tympanic). Ear temperatures are accurate after 6 months of age, but not before.

  • Armpit (axillary). This is the least reliable but may be used for a first pass to check a child of any age with signs of illness. The provider may want to confirm with a rectal temperature.

  • Mouth (oral). Don’t use a thermometer in your child’s mouth until they are at least 4 years old.

Use the rectal thermometer with care. Follow the product maker’s directions for correct use. Insert it gently. Label it and make sure it’s not used in the mouth. It may pass on germs from the stool. If you don’t feel OK using a rectal thermometer, ask the healthcare provider what type to use instead. When you talk with any healthcare provider about your child’s fever, tell them which type you used.

Below are guidelines to know if your young child has a fever. Your child’s healthcare provider may give you different numbers for your child. Follow your provider’s specific instructions.

Fever readings for a baby under 3 months old:

  • First, ask your child’s healthcare provider how you should take the temperature.

  • Rectal or forehead: 100.4°F (38°C) or higher

  • Armpit: 99°F (37.2°C) or higher

Fever readings for a child age 3 months to 36 months (3 years):

  • Rectal, forehead, or ear: 102°F (38.9°C) or higher

  • Armpit: 101°F (38.3°C) or higher

Call the healthcare provider in these cases:

  • Repeated temperature of 104°F (40°C) or higher in a child of any age

  • Fever of 100.4° F (38° C) or higher in baby younger than 3 months

  • Fever that lasts more than 24 hours in a child under age 2

  • Fever that lasts for 3 days in a child age 2 or older
