Q:      I have had a sore throat and cough for 3 days. How do I know if I have a cold or the flu?

A:      This is the flu season. In fact this year, the flu (influenza) has been rampant across the U.S. The number of flu cases seems to be waning in Texas, however by no means is the danger over. You ask a very important question. Not every sore throat, cough or fever means that you have the flu. The Common Cold and Flu symptoms can sometimes overlap. If you’re trying to determine if your symptoms are a cold or the flu, the following may help, but it can often be difficult to differentiate, and may require a visit to your doctor.

What are the symptoms of a cold?

Cold symptoms can last from 2 days to 2 weeks, and often include:

• Sore throat
• Mucus buildup in nose
• Swelling of sinuses
• Sneezing
• Cough
• Headache
• Tiredness

 

What are the symptoms of the flu?

 

The flu usually comes on suddenly, though people can host the flu virus for 1-4 days before symptoms begin to emerge. People feel some or all of these symptoms:

 

• Fever often with chills
• Cough
• Sore throat
• Runny or stuffy nose
• Muscle or body aches
• Headaches
• Fatigue
• Vomiting and diarrhea (more common in children)
• Note: Not everyone with flu will have a fever.

 

So, What are the key differences?

 

• A fever (generally between 100 and 102) usually accompanies the flu and lasts 3 to 4 days. It is rare to develop a fever from a cold.
• Severe headaches and body-aches often accompany the flu, while these symptoms are slight or non-existent with colds.
• The flu usually causes severe fatigue, which is not a general symptom of the common cold, despite feeling a bit run-down.
• A stuffy nose, sore throat and sneezing more often indicate a cold than they do the flu.

 

How can flu be prevented?

• Wash hands often, and use hand sanitizers.
• Don’t share cups or utensils.
• Get a flu vaccination – it’s not too late!

 

What to do if you have the flu?

• People with mild cases of the flu should get plenty of rest and fluids.
• Those with severe symptoms, such as a high fever or difficulty breathing, should see a doctor and may be prescribed antiviral drugs such as Tamiflu or Relenza.

These medicines reduce the severity and shorten the duration of influenza (flu) symptoms by 1 to 1½ days if given within 48 hours of the onset of symptoms.

• Note: Children should not be given aspirin without a doctor’s approval.
