Xstrata Copper, the fourth largest global copper producer says:
“…The health benefits of copper have been known by man since ancient times. The Egyptians used copper to make drinking vessels and water pipes, while others wore copper bracelets to ward off disease. Although the Ancient Egyptians and Greeks may not have realized it, copper is an effective antimicrobial material destroying 99.9% of bacteria within two hours of exposure…” source
“Laboratory testing shows that, when cleaned regularly, Antimicrobial Copper™ kills greater than 99.9% of [...] bacteria within 2 hours of exposure: [...] Antimicrobial Copper surfaces are a supplement to and not a substitute for standard infection control practices. Just like other antimicrobial products, they have been shown to reduce microbial contamination, but do not necessarily prevent cross contamination; users must continue to follow all current infection control practices…”
“Antimicrobial Copper can significantly reduce environmental contamination, making it the material of choice for frequently touched surfaces in situations where hygiene is of paramount importance [...] Copper Centres are now raising awareness among the infection control professionals, architects, designers, healthcare estates and facilities managers, to progress the adoption of Antimicrobial Copper technology for hygienic healthcare applications.” source:
