We were surprised that bankers and accountants came up so high. I really expected lawyers, maybe television producers and radio announcers (to rank high). In my experiences, they're pretty bad.

Most of the common infections -- colds, flu, diarrhea -- you get environmentally transmitted either in the air or on surfaces you touch. I think people under-rate surfaces.

Toilets get a bad rap. So does the door on the way out.

Nobody cleans their desk because it's a personal space.

Keyboards are a lunch counter for germs. We turn them over in a lot of studies and we are amazed at what comes out of a keyboard.

We were pleased to find a decrease in bacteria levels. Perhaps people are becoming more aware of germs in their office and doing something about it.

Teachers were not surprising because kids are so darn germy. Some of the others kind of surprised us, like the DJ.

We spend more and more time at our desks, but we haven't learned to bring the hygiene habits we have at home to the office.

Most people don't realize that they actually should wash their hands after they make dinner and also after they do the laundry.
