Influenza activity has reached the peak levels seen in 2014 (influenza activity in 2014 was the highest seen since the 2009 pandemic). Activity this year will match and may surpass 2014.
Influenza is a highly contagious respiratory illness caused by influenza viruses. There are three main types of influenza virus that cause infection in humans - types A, B and C - and many sub-types or strains. Influenza can occur throughout the year but activity usually peaks in winter.
Influenza viruses can spread easily. Always carry a tissue and use it to catch your cough or sneeze. If you don’t have a tissue, coughing into your elbow is better than into your hands.
Influenza viruses can live for several hours on tissues. Throw used tissues in a rubbish bin as soon as possible.
Hands can transfer viruses and other germs to every surface you touch. Wash your hands thoroughly and often, especially after coughing, sneezing or blowing your nose.
Wash hands for at least 10 seconds or use an alcohol-based hand rub.
Wait at least 24 hours after your fever resolves before you return to work or other public activities so you do not infect others. Keep sick children away from school and other activities.
Influenza vaccine is strongly recommended and available free for all people aged 65 years and over, Aboriginal children aged from 6 months to 4 years, Aboriginal people aged 15 years and over, pregnant women, and all people aged 6 months and over with medical conditions predisposing to severe influenza.
