Is a highly infectious and very common viral illness that is spread by coughs and sneezes. It's not the same as the common cold. Flu is caused by a different group of viruses and symptoms tend to be more severe and last for longer.
You can catch flu - short for influenza - all year round, but it is especially common in winter, which is why it is also known as 'seasonal flu'.
Flu causes a sudden high temperature, headache and general aches and pains, tiredness and sore throat. You can also lose your appetite, feel nauseous and have a cough. Flu symptoms can make you feel so exhausted and unwell that you have to stay in bed and rest until you feel better.
Better known as the winter vomiting bug, is the most common stomach bug in the UK, affecting people of all ages.
The virus, which is highly contagious, causes vomiting and diarrhoea. As there is no specific cure, you have to let it run its course, but it should not last more than a couple of days. If you get norovirus, make sure you drink plenty of fluids to avoid dehydration and practise good hygiene to help prevent it from spreading.
