Colds and flu symptoms

Infographic

How can you tell if you have a cold or the flu? Explore this infographic to compare their symptoms and debunk the most common myths.

Symptoms of a cold can include:

  • sore throat
  • fever (a temperature of 38 degrees Celsius or higher)
  • sneezing
  • blocked or runny nose
  • cough.

If you have green or yellow mucous coming out of your nose then it's a sign your immune system is fighting the infection. It doesn't mean your cold is getting worse or that you have a bacterial infection. But if your symptoms don't improve after 10 days, or they get worse, then see your doctor.

Symptoms for influenza (flu) can include:

  • sudden fever with a temperature of 38.5 degrees Celsius or above
  • dry, chesty cough
  • headache

  • chills
  • aching muscles
  • limb or joint pain
  • diarrhoea or upset stomach
  • sore throat
  • runny or blocked nose

  • loss of appetite.

  • a cough lasting longer than 3 weeks
  • can’t or won’t drink fluids
  • vomit frequently
  • complain of intense headache
  • are pale and sleepy
  • have chest pain
  • experience breathing difficulties
  • develop a rash with fever
