Flu or Cold? Know the Difference

Seasonal & Safety • Medically reviewed September 2022by the Cedarcrest Health clinical content committee

Colds and flu share some symptoms, which can make it hard to tell them apart, especially in the first day or two of feeling unwell. Knowing some general differences can help you decide how to care for yourself and when to seek medical attention.

Comparing Symptoms

Colds tend to develop gradually and are usually milder, often bringing a runny or stuffy nose, sneezing, and a mild cough. The flu tends to come on more suddenly and often includes fever, body aches, chills, and fatigue that can feel much more intense than a typical cold.

Both illnesses are caused by viruses and are contagious, spreading through droplets from coughing or sneezing as well as contact with contaminated surfaces. Both usually run their course within one to two weeks, though flu recovery can take longer.

Caring for Yourself at Home

• Rest and drink plenty of fluids.
• Wash hands often to avoid spreading illness to others.
• Stay home when you are contagious, especially with a fever.
• Watch for warning signs such as difficulty breathing or symptoms that worsen after seeming to improve.

Annual flu vaccination remains one of the best ways to reduce your risk of getting the flu or having a severe case if you do get sick. It is recommended for most people each fall.

If your symptoms are severe, you are at higher risk for complications, or you are simply unsure whether you have a cold or the flu, talk with your Cedarcrest Health primary care provider, or call (814) 555-2650.
