Have I got

the flu?

Here are the early flu symptoms to look out for:1,2

  • Fever of 38°C - 40°C
    (although not everyone with the flu will have a fever)
  • Body aches
  • Headaches
  • Chills
  • Weakness and fatigue
  • Cough
  • Sore throat
  • Runny or stuffy nose
  • Diarrhea or vomiting
    (more common in children)

Of course, everybody is different, and while some people with the flu will get all of these symptoms, others might only experience a few.1


or the flu?


Unlike those associated with the flu, cold symptoms come on gradually. They include:1

  • Runny or stuffy nose
  • Sore throat
  • Mild/moderate cough
  • Sneezing

Colds do not usually require any specific measures beyond taking over-the-counter medications to help ease symptoms,  and you can normally get these from your local pharmacy.
