Forget dusting... keep germs at bay by scrubbing your doorknobs and light ...

After vacuuming the house from top to bottom, clearing the dishes and tidying up, many feel the weekly clean is done and it’s time to put their feet up.

But have you remembered to scrub the doorknobs and light switches?

Hygiene experts have warned these often forgotten surfaces, which we spend the most time touching, can pass on bugs like norovirus and the flu.

After vacuuming the house from top to bottom, clearing the dishes and tidying up, many feel the weekly clean is done and it’s time to put their feet up. But have you remembered to scrub the doorknobs and light switches?

It may not actually matter if a family go a fortnight without vacuuming, unless someone is allergic to dust mites. The same goes for making the bed, the less perfect housewives and husbands may be glad to hear.

But a doorknob or light switch, or a bathroom surface, could transfer bacteria which then gets into the body when someone next eats with their hands or rubs their eyes.

The advice to ‘identify critical points for transmitting infection’ is reported in today’s New Scientist magazine.

Dr Sally Bloomfield, a microbiologist and honorary professor at the London School of Hygiene and Tropical Medicine, said: ‘I think people forget to clean doorknobs and light switches because we focus on getting rid of visible dirt.

‘If you look at a door handle, you will say it is clean, I can’t see any dirt on that, but the thing we don’t realise is that what is visibly clean is not hygienically clean.

‘Someone suffering from norovirus, for example, could have thousands of particles on their hands. Their hands may look perfectly clean and the door handle may look perfectly clean, but there are more than enough particles to infect the next person who opens the door and touches their mouth.’
