Influenza (flu) and cold are two common respiratory illnesses that often have similar symptoms. While flu is usually more severe than a cold, it can sometimes be difficult to tell the difference between the two.

But understanding the differences between them is important because treatment options can vary. Here’s a closer look at the signs and symptoms of flu and cold and how to spot the differences.

Causes of Flu and Cold

Influenza and cold are both caused by viruses, but different viruses cause each illness. Influenza is caused by the influenza virus, while cold can be caused by many different viruses, such as the rhinovirus and coronavirus.

Both viruses are highly contagious and can be transmitted through close contact with an infected person or indirect contact with surfaces contaminated with the virus.

Symptoms of Flu and Cold

The symptoms of flu and cold may overlap, which can make it difficult to distinguish between them. However, flu symptoms tend to be more severe and come on more suddenly than cold symptoms. Here are some common symptoms of flu and cold:.

Flu Symptoms

Fever: Typically above 100 degrees Fahrenheit.

Aches: Muscle aches and headaches.

Fatigue: Extreme exhaustion and weakness lasting several days.

Cough: Dry cough that may become severe.

Sore throat: Scratchy, irritated throat.

Runny or stuffy nose: Nasal congestion or discharge.

Cold Symptoms

Sore throat: Scratchy, irritated throat.

Cough: Mild to moderate cough.

Fever: Possibly a low-grade fever in children.

Differences in Duration of Symptoms

One major difference between flu and cold is the duration of symptoms. While both illnesses can cause similar symptoms, flu symptoms are typically more severe and will last longer than cold symptoms.

Cold symptoms can last for one to two weeks, while flu symptoms can last for several weeks, with fatigue and weakness lasting even longer. In some cases, complications from the flu can occur, such as pneumonia, which can be life-threatening.

On the other hand, colds rarely cause serious health problems.

Treatment for Flu and Cold

Treatment options for flu and cold vary because they are caused by different viruses. For most people, both illnesses can be managed with self-care measures to relieve symptoms. Here are some treatment options for flu and cold:.

Treatment for Flu

Antiviral medication: Prescription antiviral drugs can help shorten the duration of flu symptoms and reduce the risk of complications. These drugs work best when taken within 48 hours of symptom onset.

Rest and fluids: Get plenty of rest and drink fluids to help your body recover from the illness.

Pain relievers: Over-the-counter pain relievers such as acetaminophen and ibuprofen can help to relieve fever and body aches.
