Both the common cold and influenza are respiratory illnesses, which is why their symptoms often overlap. However, flu symptoms tend to be more intense and come on more suddenly, while cold symptoms are usually milder and develop gradually.

Flu Symptoms

Fever
A mild fever can happen with a cold, especially early on. However, a temperature of 102°F or higher is much more characteristic of the flu. Fever with a cold usually lasts 1–2 days, while flu-related fever often lasts longer.

Fatigue and Exhaustion
Colds may make you feel “under the weather,” but the flu often causes severe fatigue or exhaustion, making even simple activities feel overwhelming.

Aches and Pains
Body aches and headaches are mild or uncommon with colds, but full-body aches and intense headaches are classic flu symptoms.

Other Flu Symptoms May Include:

• Cough
• Sore throat
• Nasal congestion
• Decreased appetite
• Tiredness

Not everyone with the flu will have a fever, but many recover within 3–13 days. Some people, especially those at higher risk, may develop complications.

Common Cold Symptoms

Sneezing
Frequent sneezing is often one of the first signs of a cold. While sneezing can occur with the flu, it’s far more common with colds or allergies.

Stuffy or Runny Nose
A congested or constantly running nose is a key cold symptom. The flu can cause nasal symptoms too, but they’re usually less pronounced.

Sore Throat
Sore throats are common with colds and can make symptoms feel worse than they actually are. While less common with the flu, a sore throat may also indicate strep throat if it persists without other cold symptoms.

Cough
Cough occurs with both illnesses, but a cold typically is a wet cough with phlegm. If your cough worsens or doesn’t improve, it’s worth getting checked.

Recovery Time
Most people recover from a cold in 7–10 days, though mild symptoms may linger a bit longer.

Treating Cold and Flu Symptoms

There’s no cure to make a cold or flu disappear overnight. Treatment focuses on symptom relief and supporting your body’s recovery:

• Rest
• Drink plenty of fluids
• Use over-the-counter medications as directed for fever, congestion, or aches

If symptoms are severe, persistent, or interfering with daily life, medical evaluation is recommended.

How to Help Stop the Spread of Illness

Whether it’s a cold or the flu, preventing the spread protects your family, coworkers, and community.

If You’re Not Sick:

• Wash hands with soap and water for at least 20 seconds.
• Use alcohol-based hand sanitizer if soap and water aren’t available.
• Clean and disinfect frequently touched surfaces.
• Avoid touching your eyes, nose, and mouth.

If You Are Sick:

• Cover your mouth and nose when sneezing or coughing.
• Stay home whenever possible.
• Wear a mask when visiting healthcare facilities if requested.
• Avoid close contact with others until symptoms improve.
