Upper Respiratory Infection (URI, or Common Cold)

What is an upper respiratory infection (URI)?

An upper respiratory infection (URI), also known as the common cold, is one of the most common illnesses, leading to more doctor visits and absences from school and work than any other illness every year. It is estimated that during a one-year period, people in the US will suffer one billion colds. Caused by a virus that inflames the membranes in the lining of the nose and throat, colds can be the result of more than 200 different viruses. However, among all of the cold viruses, the rhinoviruses and the coronaviruses cause the majority of colds.

Facts about an URI or cold:

When is the "cold" season?

Children are most likely to have colds during fall and winter, starting in late August or early September until March or April. The increased incidence of colds during the cold season may be attributed to the fact that more children are indoors and close to each other. In addition, many cold viruses thrive in low humidity, making the nasal passages drier and more vulnerable to infection.

What causes the common cold?

There are many different types of viruses that cause the common cold. In fact, over 200 different varieties of viruses can cause the symptoms of a cold. The most common virus is called the rhinovirus. Other viruses include the coronavirus, parainfluenza virus, adenovirus, enterovirus, and respiratory syncytial virus.

After the virus enters your child's body, it causes a reaction - the body's immune system begins to react to the foreign virus. This, in turn, causes:

How did my child catch a cold?

In order to catch a cold, your child must come in contact with one of the viruses that cause a cold, from someone else who is affected. The cold virus can be transmitted in the following ways:

What are the symptoms of a common cold?

The symptoms of a cold start from one to three days after your child has been in contact with the cold virus. Usually, the symptoms last about one week, but this varies in each child, and may last even up to two weeks. The following are the most common symptoms of a cold. However, each child may experience symptoms differently. Symptoms may include:

Infants:

Older children:

The symptoms of the common cold may resemble other conditions or medical problems. Always consult your child's physician for a diagnosis.

How is a cold different from the flu?

A cold and the flu (influenza) are two different illnesses. A cold is relatively harmless and usually clears up by itself after a period of time, although sometimes it may lead to a secondary infection, such as an ear infection. The flu can also be harmless but may progress to a more complicated illness, such as pneumonia and even death. What may seem like a cold, could, in fact, be the flu. Be aware of these differences:

Cold Symptoms Flu Symptoms
Low or no fever High fever
Sometimes a headache Commonly a headache
Stuffy, runny nose Sometimes a stuffy nose
Sneezing Sometimes sneezing
Mild, hacking cough Cough, may progress
Slight aches and pains Often severe aches and pains
Mild fatigue Fatigue, may persist
Sore throat Sometimes a sore throat
Normal energy level Exhaustion

Who is at greater risk for catching the common cold?

Children suffer more colds each year than adults, due to their immature immune systems and to the close physical contact with other children at school or daycare. In fact, the average child will have between six to eight colds a year, while the average adult will get two to four colds a year. However, the average number of colds for children and adults will vary.

How is the common cold diagnosed?

Most common colds are diagnosed based on reported symptoms. However, cold symptoms may be similar to certain bacterial infections, allergies, and other medical conditions. Always consult your child's physician for a diagnosis.

Treatment for the common cold:

It is important to remember that there is no cure for the common cold and that antibiotics will not help treat a common cold. Medications are used to help relieve the symptoms, but will not make the cold go away any faster. Therefore, treatment is based on helping the symptoms and supportive care. Specific treatment will be determined by your child's physician based on:

Treatment may include the following:

To help relieve the congestion and obstruction in the nose for younger children, consider the following:

Do not give aspirin to a child who has fever without first contacting the child's physician. Aspirin, when given as treatment for viral illnesses in children, has been associated with Reye syndrome, a potentially serious or deadly disorder in children. Therefore, pediatricians and other healthcare providers recommend that aspirin (or any medication that contains aspirin) not be used to treat any viral illnesses (such as colds, the flu, and chickenpox) in children.

There are other medications for congestion, cough, or runny noses.

Discuss your options with your child's physician.

Can I prevent my child from getting colds?

Taking proper preventive measures can reduce the risk of your child developing a cold. Preventive measures may include the following:

What are the possible complications from having a cold?

The following are some of the complications that might occur if your child gets a cold:

Consult your child's physician for further evaluation.

Cold weather and colds:

Contrary to popular belief, cold weather or getting chilled does not cause a cold, according to the National Institute of Allergy and Infectious Diseases (NIAID). However, more colds do occur during the cold season (early fall to late winter), which is probably due to a variety of factors, including the following:

Antibiotics overuse:

Antibiotic overuse in children has become a common problem, aggravated by parental pressure for the medication, according to the American Academy of Pediatrics (AAP). In 1980, 4.2 million prescriptions were written for amoxicillin, an oral antibiotic to treat ear infections. In 1992, the number of prescriptions had grown to 12.3 million (194 percent increase). Use of another antibiotic to treat ear infections, cephalosporins, increased from 876,000 prescriptions in 1980 to 6.8 million in 1992 (a 687 percent increase).

However, parents and physicians are heeding warnings from healthcare professionals about antibiotic overuse. In a 2002 study, researchers found that antibiotic prescriptions per 1,000 children and adolescents under the age of 15 dropped by 40 percent from the year 1990 to 2000. Antibiotic prescriptions resulting from physician's visits also dropped by 29 percent. For otitis media, specifically, prescriptions dropped by 47 percent.

Overuse of antibiotics is leading to strains of diseases that are becoming resistant to the medication, making it harder to treat patients. All too often, antibiotics have been prescribed for conditions such as colds, fluid in the middle ear, or bronchitis, which do not respond to antibiotics, according to the Centers for Disease Control and Prevention (CDC). Antibiotics are only effective in treating bacterial infections.

The key to preventing overuse of antibiotics is education of the parents and physicians in the appropriate use of antibiotics, according to the AAP. Some tips to remember when taking antibiotics, according to the American Medical Association (AMA), include the following:
