What are the Symptoms of Flu?
Common Symptoms
Flu symptoms in the United Kingdom are typically similar to those experienced globally. Common symptoms include:
- High fever (38°C or higher)
- Chills and sweats
- Headache
- Persistent dry cough
- Muscle and joint aches and pains

Gastrointestinal Symptoms
While less common, some individuals in the UK who contract the flu may experience gastrointestinal symptoms such as:

- Vomiting
- Diarrhoea
Duration of Symptoms
Typically, flu symptoms last for about a week, though the fatigue and cough can persist for a couple of weeks more. It’s important to rest and stay hydrated during this period to aid recovery.
When to Seek Medical Help
In most cases, the flu will resolve without medical intervention. However, it is important to seek medical help if you experience severe symptoms such as:
- Difficulty breathing or shortness of breath
- Chest pain or pressure
- Sudden dizziness or confusion
- Severe or persistent vomiting
- Flu-like symptoms that improve but then return with a fever and worse cough
High-risk groups, including young children, elderly individuals, pregnant women, and those with pre-existing health conditions, should be especially vigilant and seek professional advice if they suspect flu infection.
Preventing Flu
To reduce the risk of contracting the flu, the NHS recommends annual flu vaccinations, especially for high-risk groups. Additionally, maintaining good personal hygiene, such as frequent handwashing, and avoiding close contact with infected individuals can help prevent the spread of the virus.
