What is the common cold in children?

The common cold (upper respiratory infection) is one of the most common illnesses in children. Each year it leads to more healthcare provider visits and missed days from school and work than any other illness. Millions of people in the U.S. will get a cold each year.

Here are a few facts:

• Most children will have at least 6 to 8 colds a year. Children who attend daycare will have more.

• Colds may occur less often after age 6.

• Children are more likely to have colds during fall and winter.

What causes the common cold in a child?

Colds happen when a virus irritates (inflames) the lining of the nose and throat. Colds can be caused by more than 200 different viruses. But most colds are caused by rhinoviruses.

To catch a cold, your child must come in contact with someone who is infected with one of the cold viruses. The cold virus can be spread:

• Through the air. If a person with a cold sneezes or coughs, small amounts of the virus can go into the air. Then if your child breathes in that air, the virus will stick inside your child’s nose (nasal membrane).

• By direct contact. This means that your child touches an infected person. A cold is easy for children to spread. That’s because they touch their nose, mouth, and eyes often and then touch other people or objects. This can spread the virus. It’s important to know that viruses can be spread through objects, such as toys, that have been touched by someone with a cold.

Which children are at risk for the common cold?

All children are at risk for the common cold. They are more likely than adults to get a cold. Here are some reasons why:

• Less resistance. A child’s immune system is not as strong as an adult’s when it comes to fighting cold germs.

• Winter season. Most respiratory illnesses happen in fall and winter, when children are indoors and around more germs. The humidity also drops during this season. This makes the passages in the nose drier and at greater risk for infection.

• School or daycare. Colds spread easily when children are in close contact.

• Hand-to-mouth contact. Children are likely to touch their eyes, nose, or mouth without washing their hands. This is the most common way germs are spread.

What are the symptoms of the common cold in a child?

Cold symptoms start from 1 to 3 days after your child has been in contact with the cold virus. Symptoms usually last about 1 week. But they may last up to 2 weeks. Symptoms may be a bit different for each child.

In babies, cold symptoms may include:

• Trouble sleeping

• Fussiness

• Congestion in the nose

• Sometimes vomiting and diarrhea

• Fever

Older children may have:

• Stuffy, runny nose

• Scratchy, tickly throat

• Watery eyes

• Sneezing

• Mild hacking cough

• Congestion

• Sore throat

• Achy muscles and bones

• Headaches

• Low-grade fever

• Chills

• Watery discharge from the nose that thickens and turns yellow or green

• Mild tiredness (fatigue)

These symptoms may seem like other health problems, such as the flu. Make sure your child sees his or her healthcare provider for a diagnosis.

How is the common cold diagnosed in a child?

Most common colds are diagnosed based on symptoms. But cold symptoms may seem like other bacterial infections, allergies, and health problems.

How is the common cold treated in a child?

There is no cure for the common cold. Most children recover from colds on their own. Antibiotics don’t work against viral infections, so they are not prescribed. Instead, treatment is focused on helping ease your child’s symptoms until the illness passes. To help your child feel better:

• Give your child plenty of fluids, such as water, electrolyte solutions, apple juice, and warm soup. This helps prevent fluid loss (dehydration).

• Make sure your child gets plenty of rest.

• To ease nasal congestion, try saline nasal sprays. You can buy them without a prescription, and they're safe for children. These are not the same as nasal decongestant sprays. These may make symptoms worse.

• Keep your child away from tobacco smoke. Smoke will make the irritation in the nose and throat worse.

• Use children’s-strength medicine for symptoms. Discuss all over-the-counter (OTC) products with your child’s healthcare provider before using them. Don't give OTC cough and cold medicines to a child younger than 4 years old unless the provider tells you to do so. For children between the ages of 4 and 6 years, only use OTC products when recommended by your child's healthcare provider.

• Never give aspirin to a child age 18 or younger who has a cold or flu. It could cause a rare but serious condition called Reye syndrome.

• Never give ibuprofen to an infant age 6 months or younger.

• Keep your child home until he or she has been fever-free for 24 hours.

• Use a cool-mist humidifier in your child's room at night to make breathing easier.

What are possible complications of the common cold in a child?

Some of the complications that might occur if your child gets a cold include:

• Ear infections

• Sinus infections

• Pneumonia

• Throat infections

How can I help prevent the common cold in my child?

To help children stay healthy:

• Keep children away from people with a cold.

• Teach children to wash their hands often. Have them wash their hands before eating, and after using the bathroom, playing with animals, or coughing or sneezing. Carry an alcohol-based hand gel for times when soap and water aren’t available. The gel should be at least 60% alcohol.

• Remind children not to touch their eyes, nose, and mouth.

• Make sure toys and play areas are properly cleaned, especially if several children are playing together.

When should I call my child’s healthcare provider?

Contact your child’s healthcare provider right away if your child has:

• A fever of 100.4°F (38°C) or higher, or as directed by the healthcare provider

• Symptoms that last more than 10 days

• Symptoms that don't get better after taking over-the-counter medicines
