Copper’s Essential Role in Protecting Public Health

Every day, high-touch surfaces present health risks to people in public spaces, and especially the most vulnerable in healthcare. In fact, of every 100 hospitalized patients at any given time, seven will get at least one healthcare-acquired or “hospital infection”.

With naturally antimicrobial properties, copper can kill up to 99.9% of bacteria on surfaces within two hours of exposure and slow the spread of diseases.

In this infographic from our sponsor Teck, we explore copper’s bacteria-fighting abilities and its crucial role in public health.

How Copper Kills Bacteria

Due to its powerful antimicrobial properties, copper kills bacteria in sequential steps:

• First, copper ions on the surface are recognized by the bacteria as an essential nutrient and enter cell.
• Then, a lethal dose of copper ions interferes with normal cell functions.
• Finally, the copper binds to the enzymes, impeding the cell from breathing, eating, digesting, or creating energy.

This rapid killing mechanism prevents cells from replicating on copper surfaces and significantly reduces the amount of bacteria living on the surface.

Antimicrobial copper is effective against bacteria that causes common diseases like staph infections and E. coli that causes foodborne illness. The metal continuously kills bacteria and never wears out.

Besides bacteria, researchers are currently studying copper’s impacts on the virus that causes COVID-19. A previous study suggested that SARS-CoV-2 was completely destroyed within four hours on copper surfaces, as compared to 24 hours on cardboard, and (Read more...)
