Copper is known to have antimicrobial properties. The use of copper for health remedies has been seen ancient times. Michael G. Schmidt, a professor of microbiology and immunology at the Medical University of South Carolina stated that “Copper is truly a gift from Mother Nature in that human race has been using it for over eight millennia.” For thousands of years, long before people knew about germs or viruses, people have known of copper’s disinfectant powers.
Ways Copper Kills Germs
According to Bill Keevil, a microbiology researcher at the University of Southampton (U.K.) copper actively attacks germs on contact.
When a microbe lands on copper, ions blast the pathogen like an onslaught of missiles, preventing cell respiration and punching holes in the cell membrane or viral coating and creating free radicals that accelerate the kill, especially on dry surfaces. Most importantly, the ions seek and destroy the DNA and RNA inside a bacteria or virus, preventing the mutations that create drug-resistant superbugs.
Keevil also has studied the antimicrobial effects of copper for more than two decades. He has watched in his laboratory as the simple metal slew one bad bug after another. He began with the bacteria that causes Legionnaire's Disease and then turned to drug-resistant killer infections like Methicillin-resistant Staphylococcus aureus (MRSA). He tested viruses that caused worldwide health scares such as Middle East Respiratory Syndrome (MERS) and the Swine Flu (H1N1) pandemic of 2009. In each case, copper contact killed the pathogen within minutes. "It just blew it apart," he says.
EFFECTIVENESS OF COPPER ON COVID-19
Brand new research published in the New England Journal of Medicine found that copper can be effective against SARS-CoV-2, the virus responsible for the coronavirus pandemic. The study showed that after four hours, the virus was no longer infectious on copper's surface. In comparison, coronavirus was still infectious on plastic surfaces after 72 hours.
