We don't want to make people overly paranoid here. You can reduce your risk of getting colds and flu by a few simple actions. You are always gambling with germs. You just want to keep the odds in your favor.
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.
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.
Most people don't realize that they actually should wash their hands after they make dinner and also after they do the laundry.
