Influenza is often confused with a common cold, but compared to a cold's typical sneezing and nose stuffiness, the flu is a serious illness that can lead to death.
In fact, it's a highly contagious viral infection of the respiratory tract, and we encourage you and your family to get vaccinated each year.
Flu symptoms can include a fever, chills, headache, muscle aches, vomiting and diarrhea, among a number of other symptoms.
You should see a healthcare provider if you develop more severe symptoms: a high temperature; you seem to get better but then feel worse than before; trouble breathing, confusion or you simply feel much worse.
In addition to protecting your family with an annual flu shot, covering your mouth during coughs and sneezes, hand washing and keeping away from others with the flu help reduce the risk.
