It’s that time of year when cold and flu viruses are rampant. One minute you feel fine, and the next, you’re fighting off a runny nose, cough, and a sore throat.
But is it a cold or the flu? While the two illnesses share many symptoms, there are differences that can help you determine which one you have.
What is a Cold?
A cold is a viral infection of the upper respiratory system. It’s the most common illness in humans and can be caused by over 200 different viruses. The symptoms of a cold are usually mild and last for a few days to a week. They include:.
- Runny or stuffy nose
- Sneezing
- Sore throat
- Coughing
- Watery eyes
Colds are often spread from person to person through the air or by touching a contaminated surface. While there is no cure for a cold, you can treat the symptoms with over-the-counter medications, rest, and fluids.
What is the Flu?
The flu is a viral infection that affects the respiratory system. It’s caused by the influenza virus and can lead to serious health complications if left untreated.
The symptoms of the flu are more severe than those of a cold and can last for up to two weeks. They include:.
- Fever
- Body aches
- Fatigue
- Coughing
- Sore throat
- Runny or stuffy nose
- Headache
- Chills
The flu can be transmitted through the air or by touching a contaminated surface. It’s important to seek medical attention if you suspect you have the flu, especially if you are at risk for complications.
