Flu is a common infection that can easily spread to other people.
The symptoms of flu are similar to a very bad cold. They include a high temperature, an aching body, tiredness and a headache.
Flu will usually get better in about a week if you rest, keep warm, drink plenty of fluids and take painkillers. Antibiotics do not help with flu.
You can help avoid flu by getting the flu vaccine every year.
