A spirited campaign to promote "hand hygiene" is under way at the University of Central Florida Orlando campus, and the urinal toter, known as UCF 5th Guy, is its front line. Like their counterparts at many other institutions, health officials at Central Florida want students to think about the germs that lurk on their hands. And then clean them, preferably with one of 32 strategically placed hand sanitizers on the campus. Waterless hand sanitizers like Purell, Germstar, and AeroFirst, once the province of medical examination rooms, are becoming fixtures on college campuses. Dispensers are appearing in dining halls, next to elevators, at entrances to computer labs and recreational centers, and any place else students are likely to share their germs. At Central Florida, a Web site instructs students what to do if they encounter 5th Guy, whose moniker comes from a statistic that one in five men do not wash their hands after leaving a public restroom. Gimmicks like 5th Guy, a spinoff of a statewide health campaign in Florida, are key to getting students to think about hygiene, says Michael Deichen, medical director of Central Florida's health services. Simply installing dispensers of AeroFirst around campus would probably not compel students to use them, he says.
