What is it?
Influenza is a contagious infection caused by the influenza virus which typically occurs during the autumn and winter months.
Influenza is characterised by a series of symptoms that can affect the entire body. Typical symptoms of influenza include fever, headache, body aches and pains, cough and extreme tiredness. Symptoms are generally severe and occur suddenly. People suffering with influenza can be unwell for up to 14 days.
Many people think they've had the 'flu' when all they have had is the common cold.
Influenza is not like a common cold. It is a serious viral infection that usually starts in your nose and throat and can spread throughout your entire body. Influenza makes people feel miserable and for some individuals can result in hospitalisation or even death. Special care is required when children, the elderly or those with other health problems get influenza as serious complications are more likely to develop.
The influenza virus hits suddenly and is highly contagious. Many people say it's like being 'hit by a truck'. In 2005 it is estimated that 47,000 New Zealanders experienced influenza.
For the vast majority, influenza can stop you from completing your normal daily activities such as family commitments, work, sport and school.
