The flu, which is short for influenza, is a contagious respiratory illness that is caused by a virus.

It can spread rapidly through a population, and it can lead to significant morbidity and mortality, particularly among older adults, young children, and people with weakened immune systems.

What is Influenza?

Influenza is a viral infection that primarily affects the respiratory system. The symptoms of the flu typically include fever, coughing, sore throat, body aches, and fatigue, and they can last for several days.

In some cases, the flu can also cause complications, such as pneumonia, bronchitis, or sinus infections.

How does Influenza Spread?

Influenza is highly contagious, and it can spread rapidly from person to person through coughing, sneezing, and close contact.

The flu virus can also survive on surfaces for several hours, so people can become infected by touching a contaminated object or surface and then touching their mouth, nose, or eyes.
