Flu (influenza) is a highly infectious and very common viral illness that is spread by coughs and sneezes. It can make even healthy people feel very unwell for a week or more.
You can catch flu all year round, but it is especially common in winter which is why it is often known as 'seasonal flu'.

Who is at risk
Anyone aged 65 or over is more vulnerable to flu and needs extra protection.
People with underlying health conditions are also amongst the most vulnerable. Conditions and diseases which can make flu much more dangerous include:
If you have any of these conditions, even if you feel fit and healthy, flu can still seriously affect you.
How to protect against flu
The most effective way to protect against flu is to have the flu jab (vaccination) as early as possible.
If you had the flu vaccination last year, you will not necessarily be protected this year. For maximum protection, it is important to get a booster vaccination each year.

Myths and facts about flu
There are a few misconceptions about flu that have become common knowledge over the years.
Some of these are old wives tales that have been passed down the generations while others are simply bad science.
For instance, did you know:
- Antibiotics cannot cure the flu. Antibiotics are designed to kill bacteria but flu is a virus and will not respond to these type of medicines.
- Cold weather increases your chances of catching flu. This is because the flu virus thrives in colder temperatures and so can survive longer outside of the human body.
