Influenza – or the flu – is a virus that spreads quickly from person to person. Some people get very sick – influenza causes number of deaths every year.

Symptoms include fever, chills, aches, runny nose, a cough and stomach upset.

The influenza virus infects your nose, throat and lungs. The flu is normally much worse than a 'cold'. You are more likely to get the flu during winter in New Zealand. Some people get very sick and need to be hospitalised, and every year some people die from influenza.

Anyone can get influenza. However, older people, young children, pregnant women, and those with certain medical conditions are at more risk of developing serious complications from it, such as pneumonia. If you’re at higher risk, it is important to see your doctor early to find out if you need treatment.

From time to time, a new influenza virus emerges that leads to a global epidemic, also known as a pandemic. The last pandemic occurred in 2009.

Immunisation is your best defence against the flu. Flu vaccine is free for people most at risk and protects against the common forms of flu. See the Fight Flu website.

If you are concerned about the flu, call Healthline on 0800 611 116 or see your doctor or practice nurse.

The flu spreads quickly from person to person through touch. Coughing and sneezing also spreads the virus through the air. Flu can also be caught from surfaces that have been touched by people with influenza.

People with influenza can infect others, even before they have symptoms, and up to a week or longer after becoming sick. Children can infect others for a much longer period of time, even if they have no or very mild symptoms.

Signs and symptoms of influenza can include:

  • fever (a temperature of 38°C or higher)
  • cough
  • sore throat
  • runny or stuffy nose
  • body aches
  • headache
  • chills
  • stomach upset, vomiting (being sick) or diarrhoea (runny poo).

It may take between one to four days to feel symptoms after you catch influenza.

The worst symptoms usually last about five days, but coughing can last up to two to three weeks.

The best thing you can do is to get vaccinated each year. For many people, but not all, the influenza vaccine is provided free of charge.

If you think you may have influenza, consult your doctor for advice. Do not go to work, school or other activities until you are fully recovered and no longer infectious to others.

Auckland Regional Public Health Service provides information about how to manage outbreaks of influenza and is involved if a pandemic occurs.
