Copper's History: The evidence of copper's antimicrobial properties dates back to 5 or 6 B.C., with documented references in historical texts like Smith's Papyrus, an ancient Egyptian medical manuscript. Historians confirm that the Egyptians utilized copper as a potent water purification material, a medical antiseptic, and even for preserving food and water. Similar ingenuity was observed in other illustrious civilizations, such as the Romans, Greeks, and Aztecs, who recognized and harnessed copper's sterilization effects. In India, copper vessels were a common sight, employed to hold water for sterilization purposes, while ancient Chinese civilizations cleverly used copper coins to treat ailments. The Phoenicians, too, embraced copper for wound healing. This rich historical tapestry unequivocally establishes copper's remarkable versatility, playing a pivotal role in improving the quality of life through its antimicrobial properties. Moreover, the convenience of finding copper in a usable form through mining made it a favored material for countless generations.

Copper's Properties: Copper boasts powerful antimicrobial properties, swiftly neutralizing bacteria, fungi, and mold upon contact. This potency is attributed, in part, to an extra electron present in the orbit of copper molecules. This additional electron facilitates oxygen deprivation through oxygen-reduction reactions, effectively exterminating living pathogens like bacteria and fungi. Moreover, copper surfaces emit ions that target and breach the cell membranes or viral coatings of infection-causing organisms, incapacitating them in the process. Scientific studies have demonstrated that copper alloy surfaces can eradicate up to 99.9% of microorganisms in a mere 2 hours, emphasizing its rapid and robust action against germs.

Intriguingly, copper's significance extends beyond external applications. Our very own bodies harness copper to bolster the immune system's disease-fighting prowess. Even when tarnished, copper retains its ability to combat germs, making it a formidable and enduring antimicrobial agent. Unlike certain antibiotics that might contribute to drug-resistant superbugs, copper poses a more challenging adversary for pathogens, enhancing its efficacy in infection control.

Using Copper to Reduce Community and Healthcare-Acquired Infections: Copper's prowess in infection control has found practical applications in various community settings, with even century-old fixtures continuing to showcase its enduring effectiveness. For instance, the staircase handrails in New York City's iconic Grand Central Station demonstrate how copper reliably combats bacteria over time. Moreover, studies have revealed that hospital beds fitted with copper rails, footboards, and controls harbor a staggering 95% fewer bacteria compared to their plastic counterparts.

The versatility of copper extends to high-touch surfaces in both community and hospital settings, with toilet flush handles, light switches, and soap dispensers among those benefiting from copper alloys. Remarkably, if a material or surface contains 60% of greater copper, it retains its potent antimicrobial properties.

One of the most compelling attributes of copper is its autonomy as an infection control measure. Unlike methods requiring human intervention, such as frequent cleaning or handwashing, copper's natural ability to combat germs makes it a dependable and self-sustaining safeguard against infections. When combined with other materials, copper opens the door to multifunctional and innovative infection control products.

Health Canada's Pest Management Regulatory Agency (PMRA), which regulates public health claims for antimicrobial products, granted full registration for the sale and use of six different groups of antimicrobial copper alloys in July 2014. The Environmental Protection Agency (EPA) in the USA has granted approval for over 400 copper or copper-containing surfaces as "antimicrobial" since 2008, heralding a new era for infection reduction in community and healthcare settings. Copper emerges as a cost-effective solution to contain the spread of infections in hospitals and other environments.

Copper Products on the Market: A diverse array of copper and copper-containing products grace the market, offering potent infection control solutions for various settings and purposes.
