Flu is a highly infectious illness, which spreads very rapidly by coughs and sneezes from people who are already carrying the virus.

Catching flu is a nasty experience for most people. But for some people it can lead to really serious illnesses like bronchitis and pneumonia, which may mean you need hospital treatment. A lot of mainly older people die from influenza every winter.

Flu symptoms hit you suddenly and severely. They usually include fever, chills, headaches and aching muscles, and you can often get a cough and sore throat at the same time.

Colds are much less severe, and usually start gradually when you get a sore throat and stuffy or runny nose. Flu is a much more serious illness.
