Seasonal influenza (flu)
Influenza (flu) is a respiratory disease, which can be more serious than a common cold. Symptoms include headache, high fever, cough, sore throat and severely aching muscles and joints.
For most people influenza is just a nasty experience, but for some it can lead to illnesses that are more serious such as bronchitis (chest infection) and pneumonia. These illnesses may require treatment in hospital and can be life threatening especially in the elderly, people with long term conditions such as asthma and people with weakened immune systems.
