Influenza symptoms develop 1–3 days after the patient becomes infected and can include:
- fever, chills and sweating
- sore throat
- weakness
- headache and generalised muscle and joint pains (legs and back)
- a nonproductive cough that can later become severe and productive.
These symptoms can last up to approximately 1 week.
Influenza is more than a ‘bad cold’. Colds cause a runny nose, occasional mild fever but no muscle pains. Colds usually last 1–2 days.
