Flu caused by Influenza

What is Influenza (Flu)?

Influenza, more commonly known as the flu, is an acute viral infection of the respiratory tract. It is caused by the influenza virus, which can be classified into A, B, or C based on its antigenic properties. Symptoms of the flu usually include fever, body aches, fatigue, and a dry cough. It is highly contagious and can spread quickly, especially among school-aged children.

What causes the Flu?

Influenza is caused by certain types of influenza viruses. These viruses can be found in many animals, including pigs, chickens, and humans. They are spread through close contact with an infected person. When an infected person sneezes or coughs, the virus is spread in the air, and people who come into contact with the droplets can become infected.

What are the Symptoms of Flu caused by Influenza?

Common symptoms of influenza include:

  • Fever
  • Muscle aches
  • Headache
  • Fatigue
  • Dry cough
  • Sore throat
  • Runny or stuffy nose
  • Nausea, vomiting, and/or diarrhea (in children)

These symptoms can last for a few days to more than a week.

What is the Treatment for Flu caused by Influenza?

The most important treatment for the flu is prevention. The best way to prevent the flu is to get an annual flu shot. Vaccines contain killed or weakened viruses that help the body create antibodies that will protect you if you come into contact with a live virus.

If you do get the flu, rest and fluids are important to reduce the symptoms and help your body fight off the virus. Depending on your symptoms, your doctor may also prescribe antiviral drugs to help reduce the duration and severity of your illness.
