What is the Flu?

Flu is a contagious respiratory illness caused by influenza viruses that infect the nose, throat, and sometimes the lungs. It can cause mild to severe illness and, at times, can lead to death.

What are the flu symptoms?

Typical flu symptoms can include:

  • A sudden high temperature
  • An aching body
  • Feeling tired or exhausted
  • A dry cough
  • A sore throat
  • A headache
  • Difficulty sleeping
  • Loss of appetite
  • Diarrhoea or tummy pain
  • Feeling sick and being sick

It's important to note that flu symptoms can be like other respiratory illnesses, making accurate diagnosis from a medical professional essential. You can visit the NHS website for more information on the flu.

How Long Does Flu Last?

If you have flu, you generally feel ill within a few days of infection. You should begin to feel much better within a week or so, although you may feel tired for much longer.

How to Get Rid of the Flu

In the unfortunate event of contracting the flu, knowing how to care for yourself and when to seek medical attention is essential. Rest, hydration, and over-the-counter flu medications can help alleviate symptoms. However, if you experience severe symptoms such as difficulty breathing or persistent chest pain, you must contact a healthcare professional promptly.

When is flu season?

Flu season in the UK typically starts in the late autumn, around October, and can extend through to April. Peak flu activity often occurs in December and January. Various factors, including weather conditions and the strains of the virus prevalent each year, influence the timing.

High-Risk Groups in the UK

Specific individuals in the UK are at a higher risk of experiencing severe complications from the flu. This includes the elderly, young children, pregnant women, and those with underlying health conditions like asthma, diabetes, or heart disease. Protecting these vulnerable groups is a top priority during flu season.

Impact of Flu Season on the NHS

Like in other parts of the world, flu season in the UK can significantly impact public health and the healthcare system. Hospitals and healthcare providers often experience an influx of patients with flu-related symptoms, leading to increased strain on resources. This can result in longer wait times and crowded emergency rooms. Rand’s epidemiologic-economic modelling framework estimated that 2.4 million working adults could be infected with influenza, resulting in 4.8 million working days lost annually. This equates to a loss of £644 million to the UK's economy (0.04% GDP).

Prevention Measures

Prevention is the cornerstone of flu management. Individuals can take several effective measures to reduce their risk of contracting and spreading the flu. These include:

Flu Vaccination: Getting an annual flu vaccine is one of the most effective ways to protect yourself and those around you. The vaccine is typically available from GP surgeries, pharmacies, and workplaces.

Good Hygiene: Regular handwashing, covering coughs and sneezes with a tissue or elbow, and avoiding close contact with sick individuals can help prevent the spread of the virus.

Bin Used Tissues: Quickly dispose of used tissues.

Healthy Lifestyle: Maintaining a nutritious diet, staying physically active, and getting enough rest can bolster your immune system's ability to fight off infections.

Face Masks: During high flu activity or outbreaks, wearing face masks in crowded or enclosed spaces can reduce the transmission of the virus.

The Importance of Flu Vaccination

Flu vaccination is a critical strategy in reducing the impact of flu season in the UK. The vaccine protects individuals and contributes to herd immunity, making it harder for the virus to spread within the community. Despite the myths and misconceptions surrounding vaccines, flu vaccination is a safe and effective way to reduce your risk of illness and protect those around you.

From the 1st of August 2023 to the 5th of October March 2023, the NHS in England has already administered over 5 million flu vaccines.

Flu Vaccine

Who is Eligible for Free Flu Vaccine in the UK?

The NHS provides free flu jabs to certain eligible groups, including the elderly, pregnant women, and individuals with specific health conditions. However, flu vaccines are also available at pharmacies and private clinics for those outside these groups who wish to be vaccinated.


Like elsewhere, flu season in the UK is an annual challenge that requires vigilance and proactive measures. By understanding the timing, impact, and preventive strategies, individuals and communities can minimize the burden of the flu on the NHS and protect those most vulnerable. Remember, getting vaccinated and practicing good hygiene are potent tools in the fight against the flu, ensuring a healthier and safer winter for all.
