The Washington Post in its Sept. 20 edition reported that some 15 U.S. hospitals have either installed or are considering installing, copper components on “high-touch” surfaces easily contaminated with microbes, such as faucet handles and toilet levers.
On any given day, about 1 in 25 patients in acute-care hospitals has at least one health-care-associated infection, according to the Centers for Disease Control and Prevention. In 2011, about 75,000 patients with health-care-associated infections died in the hospital.
Copper can kill or inactivate a variety of pathogens by interacting with oxygen and modifying oxygen molecules. A recent study found that copper also destroys norovirus.
There has been only one published clinical trial showing how copper reduces infections in hospitals. The results, however, were striking.
