Seasonal flu is a highly infectious disease caused by a virus. It occurs every year, usually in the winter and spread rapidly through coughs and sneezes of people who are carrying the virus.
People sometimes think of flu as a bad cold, but having flu is more serious. You may be so ill that you are unable to do much more than stay in bed.
Some people are more vulnerable to the effects of seasonal flu. Flu can make existing conditions worse or can increase the risk of developing more serious illnesses such as bronchitis and pneumonia.
The best thing you can do to protect yourself against seasonal flu is to have the flu vaccination.
