Is It Cold Or Flu?

Although often confused with the common cold, influenza is more severe and poses a greater health concern. Every year, an estimated 17 million to 50 million cases of influenza are reported nationwide — many of which occur in otherwise healthy people.

Similar to the common cold, the flu can produce respiratory symptoms, such as runny nose, coughing, and sore throat. However, the influenza virus typically causes more intense symptoms, such as sudden onset of fever, headache, and muscle aches in children, adolescents, and adults. Unlike symptoms of the common cold, the fatigue and cough caused by the flu can last more than two weeks — lingering long after other symptoms subside. Children often spend a week or more in bed due to the flu. It may also lead to serious complications such as pneumonia and even death.

The table below shows some of the differences in symptoms between the common cold and the flu. This table is for information purposes only. If you or your children experience any of these symptoms, please consult a health care professional.
