Flu occurs every year, usually in the winter, which is why it’s sometimes called seasonal flu. It’s a highly infectious disease with symptoms that come on very quickly. Colds are much less serious and usually start gradually with a stuffy or runny nose and a sore throat.
A bad bout of flu can be much worse than a heavy cold. The most common symptoms of flu are fever, chills, headache, aches and pains in the joints and muscles, and extreme tiredness. Healthy individuals usually recover within 2 to 7 days but, for some, the disease can lead to hospitalisation, permanent disability or even death.
