Flu is caused by a virus.
If you have flu you may have a high fever, shivering, muscle aches and pains, headaches, sore throat, coughs, cold and sneezes. The symptoms of flu come on very suddenly. Having flu can make your asthma worse. However it may not be essential for everybody with asthma to receive the vaccination. If you feel that you are at high risk and that your asthma would be made a lot worse from catching the flu, then talk to your doctor about the vaccination.
