Flu :: SA Health

Flu

Influenza, commonly known as the flu, is a highly contagious infection of the nose, throat and lungs caused by viruses. The flu is more serious than the common cold.

Symptoms include:

  • rapid onset of fever
  • headache
  • muscle aches
  • fatigue
  • sneezing
  • running nose
  • sore throat
  • cough.

Most people recover within a week, although the cough and fatigue may last longer. Influenza can be a serious illness, potentially fatal, particularly in people aged over 65 years of age or with a chronic illness.

Treatment of flu

The recommended treatment is rest, drinking plenty of fluids and use of paracetamol for the relief of pain and fever.

You should see your local doctor if you are concerned about the symptoms or if the symptoms are getting worse. 

Antibiotics are not effective for treating the flu.

How to prevent the spread of flu

Simple ways to control the spread of flu are to wash your hands frequently, wipe over frequently touched surfaces, and cover your mouth when coughing or sneezing.

Vaccinations

The best way to protect yourself from flu is to get vaccinated. An annual flu vaccination is recommended for any person from six months of age who wishes to reduce the chance of being ill with the flu.
