From make-up bars to gadget stores, Professor Peter Collignon, director of the Infectious Diseases Unit and Microbiology at the Australian National University Medical School, reveals the surprising places where germs lurk and how to stay in the clear. By Pip Harry.
ATM cash points
After testing 38 ATM keypads in the CBD of Taipei, Chinese researchers found that each key contained an average of 1200 germs, including the ones that make us sick like E.coli and cold and flu viruses. The worst culprit is the 'Enter' button because everyone has to touch it! "ATMs are
a known hotspot for picking up bugs and numerous studies have shown germs on keypads, including golden staph, which can cause a range of infections," says Collignon.
Protect yourself:
"If you are at an ATM, use an alcohol solution afterwards and get rid of those bugs before they have a chance to transfer."
Escalator handrails
How often do you grip an escalator handrail and then moments later brush your face with your hand? Hands off! Escalator rails are a magnet for all kinds of bugs. Tests in the US have found E.coli, urine, faeces, mucus and even blood on public escalator hand rails.
Protect yourself:
If possible, try not to touch the handrails, and if you do, just rub alcohol solution on your hands afterwards. "We don't want to be so obsessive-compulsive that every time we touch someone we go and wash
our hands," says Collignon. "So when you're out in public, identify the
bigger hotspots for germs. Just think to yourself — what do hundreds of people potentially touch that's not cleaned and that I might touch? Then clean your hands accordingly."
Make-up counters
Heading to a make-up counter? You might pick up more than the latest shade of lipstick. A US study found that 67 to 100 per cent of make-up counter testers were contaminated with bacteria, including E.coli, staph and strep. Bacteria levels peaked on Saturday, traditionally the busiest shopping day of the week.
Protect yourself:
"Avoid using public samples to apply cosmetics to your face," says Collignon. "Ask for disposable applicators that you can use and throw away." If you're getting a makeover at a counter, check with the manager about the hygiene policy, such as whether they use disposable tools and testers or disinfect brushes between uses.
Gadget stores
By testing out a new iPad or smartphone at a gadget store, you're also exposing yourself to germs from hundreds of people who played before you. A 2011 study in the
Journal of Applied Microbiology found that viruses easily transfer between glass surfaces (like phone or tablet faces) and fingertips.
Protect yourself:
"If you go to a busy gadget store and there's no proper cleaning of the item between users, then you're likely to pick up some bugs," says Collignon. "The practical reality is that retailers are not going to disinfect items, so you've got to look out for yourself. Quickly wipe down the device with an antibacterial wipe before use, or rub your hands with an alcohol solution when you're done.
