Either wear gloves or wash your hands if you plan to visit an internet cafe. A Korea study ran tests for bacterial content on six of the most frequently handled public items. The results appear suitably worrying.

Shopping trolleys carry more bacteria than even public toilet door knobs. Internet cafe computer mice are the second most bacteria-carrying item found in public facilities.

Hand straps on buses were next, followed by bathroom doorknobs. Rounding out the list were elevator buttons and hand straps on subways.

Many of the items tested were found to have staphylococcus aureus bacteria. If people are infected with staphylococcus aureus through cuts on the skin, they can develop various diseases such as purulent inflammation and food poisoning. It can also contaminate food.

Washing your hands should remove most of the bacteria.
