Computer keyboard covers impregnated with a novel antimicrobial polymer significantly reduce microbial contamination

Contact with contaminated computer keyboards may contribute to the transmission of healthcare acquired infections. SPL tested a novel antimicrobial polymer, Biosafe HM 4100, which can be incorporated into polyurethane used to make keyboard covers.

Plastic keyboard covers compounded with HM4100 effectively minimized the survival of bacterial species commonly present on environmental surfaces in the healthcare setting.The Biosafe coating demonstrated efficacy in reducing viability for methicillin-resistant staphyloccus aureus (MRSA), Pseudomonas aeruginosa, E. coli, and vancomycin-resistant Enterococcus faecalis (VREF).

The article, Computer keyboard covers impregnated with a novel antimicrobial polymer significantly reduce microbial contamination, appears online and was published in the print version of American Journal of Infection Control, 41 (2013) 337-9 in April.
