Difference Between FLU AND URTI

Got sick? You might wonder if you have the flu or a URTI. Though they share some symptoms, there are key differences between these two illnesses. In this blog post, we’ll explore those differences and help you determine which one you might have. Stay healthy this season!

What is FLU?

FLU, or influenza, is a respiratory illness caused by a virus. FLU is highly contagious and can be passed from person to person through coughing, sneezing, or contact with contaminated surfaces. FLU typically occurs during the fall and winter months, and can cause severe symptoms including fever, headache, muscle aches, fatigue, and nausea. FLU can also lead to serious complications like pneumonia, bronchitis, and even death. Early diagnosis and treatment is essential for preventing serious health problems. If you think you may have FLU, see your doctor right away. FLU vaccines are also available and can help reduce your risk of infection.

What is URTI?

URTI is a medical term used to describe an infection of the upper respiratory tract. The upper respiratory tract includes the nose, sinuses, throat, and larynx. URTI can be caused by a virus, bacteria, or fungi. The most common symptoms of URTI include sore throat, runny nose, congestion, and cough. URTI is often referred to as the common cold or flu. However, URTI can also be caused by other infections, such as sinusitis, bronchitis, and pneumonia. URTI is usually treated with over-the-counter medications and home remedies. However, more severe cases may require antibiotics or hospitalization.

Difference Between FLU AND URTI

FLU AND URTI are both infectious diseases that can cause similar symptoms, such as fever, headache, and a runny nose.

  • However, FLU is much more serious than URTI and can often lead to complications, such as pneumonia.
  • FLU is caused by the influenza virus, which attacks the respiratory system.
  • URTI, on the other hand, is usually caused by a bacterial or viral infection of the upper respiratory tract, such as the sinuses, throat, or bronchial tubes.

In most cases, URTI can be treated with rest and over-the-counter medication, but FLU may require hospitalization and antibiotics. Therefore, it is important to be able to distinguish between FLU and URTI in order to receive the proper treatment.


The next time you’re feeling under the weather, be sure to take the necessary steps to figure out what type of infection you have. Knowing the difference between FLU and URTI can help you get on the mend faster.
