The common cold and the flu can cause similar symptoms, but they are different illnesses. Knowing the difference can help you decide when home care is enough and when you should seek medical attention.
What Is the Common Cold?
The common cold is usually a mild viral infection that affects the nose and throat. Most people recover within a week to ten days without medical treatment.
Colds are caused by several different viruses and commonly spread through respiratory droplets or contact with contaminated surfaces.
Typical cold symptoms include:
- Runny or stuffy nose
- Sneezing
- Mild sore throat
- Mild cough
- Watery eyes
- Mild fatigue
Cold symptoms usually develop gradually and tend to be relatively mild.
What Is the Flu?
The flu, or influenza, is a viral infection that often causes more severe symptoms than a common cold. It can lead to serious complications in some individuals.
The flu often comes on suddenly and can make you feel significantly ill.
Common flu symptoms include:
- Fever and chills
- Body aches
- Headache
- Fatigue
- Dry cough
- Sore throat
- Nasal congestion
Many people with the flu report feeling exhausted and unable to carry out normal daily activities.
How Can You Tell the Difference?
The biggest difference is typically the severity and speed of symptom onset. Flu symptoms usually appear suddenly and are more intense than cold symptoms.
Signs that may suggest a cold:
- Gradual onset
- Runny or stuffy nose
- Sneezing
- Mild fatigue
- Mild sore throat
Signs that may suggest the flu:
- Sudden onset
- Fever and chills
- Significant body aches
- Severe fatigue
- Headache
- Dry cough
While these differences can provide clues, testing may be needed to confirm a flu diagnosis.
How Are Cold and Flu Treated?
Most people recover from both illnesses with rest, hydration, and symptom management. If diagnosed early, certain patients with the flu may qualify for prescription antiviral treatment.
Treatment options for both a cold and the flu include:
- Getting plenty of rest
- Drinking fluids
- Using a humidifier
- Taking over-the-counter medications as appropriate
- Staying home to avoid spreading illness
