According to a new study, infectious bacteria can lurk in computer keyboards, especially keyboards that are shared.
University of North Carolina researchers tested 25 keyboards taken from the burn intensive care unit at the school's Health Care System.
Every keyboard tested showed signs of a staph bacterium, a common cause of infections suffered by hospitalized patients. Diptheroids, a problem for patients with weakened immune systems, were also discovered.
Scientists then compared the effectiveness of various disinfectant cleaners, including water, alcohol, chlorine and store-bought wipes made by Clorox. Although all cleaning materials were effective, the Clorox-made wipes lasted longer than the others.
