Flu is a highly infectious and very common viral illness that is spread by coughs and sneezes. It is 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 longer. You can catch flu all year round, but it is especially common in winter, which is why it is also known as ‘seasonal flu’.
