The flu, short for influenza, is a contagious respiratory illness caused by influenza viruses.
Introduction
It can cause mild to severe illness and can even lead to death in some cases. The symptoms of the flu include fever, cough, sore throat, runny or stuffy nose, body aches, headache, chills, and fatigue. Some people may also experience vomiting and diarrhea, although this is more common in children.
The flu is spread from person to person through respiratory droplets that are released when someone with the flu coughs, sneezes, or talks. The virus can also live on surfaces and be transferred to people who touch those surfaces and then touch their mouth, nose, or eyes.
The best way to prevent the flu is by getting an annual flu vaccine. Other preventive measures include washing your hands regularly, covering your coughs and sneezes, staying away from sick people, and avoiding touching your face.
If you do get the flu, treatment may include antiviral medication, which can help reduce the severity and duration of the illness. It is also important to rest, stay hydrated, and manage your symptoms with over-the-counter medications as needed.
