New research reveals over-65s have been most vigilant about maintaining good hand hygiene since this time last year.

But … some worrying habits are emerging among other groups, according to the Dettol Winter Hygiene Reports reveals. Many are failing to heed government advice to stay home when unwell and a lot of us aren’t washing our hands nearly enough.

The research found:

• The biggest decline in hand hygiene frequency compared with last year was among 18 to 24-year-olds (16 per cent), while 65 to 74-year-olds reported the greatest increase (61 per cent).

• Handwashing and/or sanitising was most frequent among older age groups, with over-75 reporting they do so at least four to five times a day (85 per cent), followed by 65 to 74-year-olds (80 per cent).

• A quarter of Aussies aged 65 to 74 and over 75 (23 per cent and 26 per cent respectively) perceive shaking hands with someone to be a germ-ridden activity versus only 13 per cent of 25 to 34-year-olds.

• Only one in three Aussies is most likely to practise good hand hygiene after sneezing or blowing their nose.

• Almost one in four would still attend an important work meeting in person if feeling unwell.

• Nearly a fifth of Aussies (19 per cent) admit to only washing or sanitising their hands two to three times per day, falling far short of recommendations.

Official advice is to:

• Carry instant hand sanitiser on you and in the car so you can maintain good hygiene practices on the go.

• Always cover your mouth and nose with your elbow when coughing or sneezing, and practise good hygiene immediately after.

• Always stay home when feeling unwell, or if you have a sniffle.

• Follow your local government health advice.
