Flu is an illness caused by the influenza virus. It occurs every year, usually in winter. It is important that you protect yourself and others from flu by helping to prevent the spread of the virus and getting the flu vaccine if you are eligible.

You can catch flu – short for influenza – all year round. It is especially common in the rainy season, which is why it is also known as ‘seasonal flu’. It usually peaks between December and March.

It is not the same as the common cold. Flu is caused by a different group of viruses. The symptoms tend to be more severe and last longer.

  • fever (typically 38–40°C) - this tends to be more severe in children

  • loss of appetite
  • aching muscles
  • vomiting or diarrhoea
  • sensitivity to light

Flu symptoms usually peak after two or three days and you should begin to feel much better within five to eight days. However, older people or those with certain medical conditions may develop complications that can lead to serious illness and can be life-threatening.
