I work with computers for a school district. My job requires that I administer about 700 computers. On a daily basis, I need to run software updates and installs as well as assist both students and staff on the use of various computer programs. This means that I am continually working on different keyboards. I'm not sure if you've ever had the opportunity to observe a class of elementary students in a computer lab but they are not very conscious of what they use to wipe a runny nose or where they sneeze. Consequently, this means that I am touching keyboards that harbor any number of thousands of germs everyday!
I purchase GermX hand sanitizer from Staples office supply when I place orders for other items. I keep it close to me at all times in each lab and carry one in my purse. The cost is a little bit less than other name brand hand sanitizers and I like the smell - it's kind of fruity! It may be just psychological but I believe that the consistent use of a hand sanitizer has helped to keep me from getting sick throughout the school year.
