Cold vs. Flu: Understanding the Basics

 

When you start feeling under the weather, it can be difficult to tell whether you have a common cold or the flu. While both are respiratory illnesses caused by viruses, they have key differences in symptoms, severity, and duration.

​

Cold Symptoms

​

The common cold is usually mild and develops gradually. Symptoms often include:

​

• Runny or stuffy nose

• Sneezing

• Sore throat

• Mild cough

• Low-grade fever (rare)

• Mild body aches or fatigue

​

Colds typically last 7–10 days, and most people recover without complications.

 

Flu Symptoms

 

Influenza, or the flu, tends to come on suddenly and is more intense than a cold. Common symptoms include:

​

• High fever (often over 100.4°F)

• Chills and sweating

• Severe body aches

• Fatigue and weakness

• Dry, persistent cough

• Sore throat

• Headache

​

The flu can lead to complications such as pneumonia, especially in young children, older adults, and those with weakened immune systems.

​

Key Differences

​

The main distinction is severity—while a cold is mild, the flu can be debilitating. Fever and body aches are much more common with the flu, whereas sneezing and congestion are more typical of a cold.

​

Prevention and Treatment

​

Both illnesses spread through respiratory droplets, so good hygiene—like frequent handwashing and covering coughs—is crucial. There is no cure for either, but rest, hydration, and over-the-counter medications can help ease symptoms. Flu vaccines are available at IEP Urgent Care and are recommended annually to reduce the risk of severe illness.

​

If you experience severe flu symptoms, difficulty breathing, or symptoms lasting longer than 10 days, visit any of our IEP Urgent Care locations for prompt treatment.

Knowing the difference between a cold and the flu can help you take the right steps for a quicker recovery and prevent the spread of illness to others.
