Copper Destroys Viruses and Bacteria. Why Isn’t It Everywhere?
It could destroy norovirus, MRSA, virulent strains of E. coli, and coronaviruses—including the novel strain currently causing the COVID-19 pandemic.

“On copper surfaces, bacteria and viruses die. When a microbe lands on a copper surface, the copper releases ions, which are electrically charged particles. Those copper ions blast through the outer membranes and destroy the whole cell, including the DNA or RNA inside. Because their DNA and RNA are destroyed, it also means a bacteria or virus can’t mutate and become resistant to the copper, or pass on genes (like for antibiotic resistance) to other microbes.
“Before people even knew what bacteria and viruses were, they knew that copper could—somehow—ward off infection. The first recorded medical use of copper is from one of the oldest-known books, the Smith Papyrus, written between 2600 and 2200 B.C. It said that copper was used to sterilize chest wounds and drinking water. Egyptian and Babylonian soldiers would similarly put the shavings from their bronze swords (made from copper and tin) into their open wounds to reduce infections.”
