Did you know that copper has antibacterial properties? In ancient times, i.e., several thousand years before the discovery of pathogens and their pathogenicity, copper was used for medicinal and hygienic purposes, for instance, in the water purification process and treatment of wounds and ulcers. In spite of the fact that this is one of the first metals known to man, it still comes as a surprise to scientists. Copper can inactivate even dangerous and antibiotic-resistant bacteria, such as methicillin resistant Staphylococcus aureus (MRSA). What is more, SARS-COV-2 has a very short lifespan on copper surfaces!
