  14. Clay et al. Am J Infect Control 2006;34:41-3. Conclusion: Feline calicivirus (and perhaps Norovirus) can survive on fomites such as computers, telephones, and faucets and may be transmitted to humans using these contaminated materials. This may necessitate regular cleaning or disinfection of these items, especially in hospitals and nursing homes and after known outbreaks of Norovirus.

  20. Rutala et al. Infect Control Hosp Epidemiol 2006;27:372 ”Our data suggest that microbial contaminatin of compute keyboards is prevalent and that kayboards may be succesfully decontaminated with disinfectants. Keyboards should be disinfectrd daily or when visibly soiled or if they become contaminated with blood.”

  27. Medigenic Keyboard Test Results • Testing in the medical surgical ICU at University College London Hospitals showed significant log reduction in bacterial contamination in the range of 0.5 log - 1.4 log (71% - 96%) at cleaning alert settings ranging from 1.5 to 12 hours. • The cleaning alert afforded a significant advantage in the Medigenic design in promoting a high level of cleaning compliance and a reduction in bacterial contamination during use in the ICU."
