No one wants to have to look at a dirty keyboard. Too often, people don’t bother to wash their hands after eating or using the restroom. Not only is this unhealthy for you in many ways… it can also end up causing you to fall ill with QWERTY Sickness.

One common bug that researchers have turned up is staphylococcus aureus, a classic causer of food poisoning, signs of which include nausea and diarrhea. Accordingly, stomach sicknesses caught from computer equipment have been dubbed "qwerty tummy" after the "Q-W-E-R-T-Y" keys on a keyboard.

Many users are at risk of becoming ill with stomach bugs, according to the consumer group Which? It warned that 'qwerty tummy', named after the first six letters on a keyboard, could sweep through workplaces after tests on equipment in its own London offices showed alarming results.
