How flu is diagnosed
- Flu can only be confirmed by a doctor after a nose or throat swab has returned positive results.
How flu affects people
- The flu virus is contagious.
- This means it spreads easily from person to person.
- The flu virus can live for up to five minutes on your hands.
- It can also live for up to a day on hard surfaces.
- It spreads when infected people cough or sneeze without covering their mouths and noses.
- It also spreads if you touch a surface that an infected person has touched.
- It takes between one and four days to start feeling unwell if you are infected.
- You can be contagious one day before symptoms start until one week after you start to feel unwell.
- Contagious means you can spread the virus to other people.
- Children and people with impaired immune systems may pass the virus on for longer.
- An impaired immune system means your body can't protect you against infection as well as other people.
How to prevent flu
You can reduce your chances of catching flu or passing it to others by:
- Getting the flu vaccine every year. The flu vaccine is recommended for everyone aged 6 months and older.
- Wash your hands often and well to get rid of germs

- Stay at least 1.5 metres away from other people
- Cover your mouth with your elbow when you cough or sneeze.
