Copper Surfaces

May Help Prevent Cold and Flu

<font face="arial, geneva, helvetica" size="2">Studies being conducted at the Univ. of Southampton, U.K., and sponsored by the Copper Development Association, New York, are proving that copper and its alloys, brass and bronze, effectively eliminate bacteria and viruses that cause illness.&nbsp;</font>

<font face="arial, geneva, helvetica" size="2">The research also has shown that stainless steel, aluminum and plastic surfaces do nothing to help eradicate germs. Once contaminated, a stainless steel doorknob, faucet or handrail can harbor bacteria and viruses until it is disinfected, usually with harsh chemicals. However, uncoated copper, including brass and bronze alloys with high copper content, are intrinsically antimicrobial and begin eliminating pathogens such as streptococcus, staphylococcus and Influenza A on contact.&nbsp;</font>

<font face="arial, geneva, helvetica" size="2">"People have been using copper to fight infections and illness for thousands of years,” said Dr. Harold Michels of the Copper Development Association. “The Egyptians used it to sterilize drinking water, the fifth century B.C. Greek doctor Hippocrates used it to treat skin irritations and open wounds, and the Aztecs used it on sore throats."&nbsp;</font>

<font face="arial, geneva, helvetica" size="2">Michels suggests that copper, brass or bronze doorknobs and handles, push plates, countertops, sinks and other frequently touched hardware may help cut down on cross-contamination and the spread of infection.&nbsp;</font>
