EPA Registers Copper Surfaces for Residual Use Against Coronavirus

The U.S. Environmental Protection Agency (EPA) announced today that it has registered certain copper alloys that have demonstrated effectiveness against viruses, including SARS-CoV-2, the virus that causes COVID-19.  This is the first antimicrobial product that is registered for "residual" use against viruses.  Traditional disinfectants only kill viruses and bacteria on the surface at the time they are used, while, in contrast, "residual" antimicrobial disinfectants kill pathogens that come in contact with the surface days,, weeks or year after the product is applied.  This "residual" antimicrobial property of copper alloy surfaces  provides a unique advantage in the fight against COVID-19 infections.

Copper Inactivates the Virus that Causes COVID-19 in One Minutes

Professor C. W. Keevil of the University of Southampton is the senior author of a important paper on the rapid inactivation of SARS-CoV-2 on copper surfaces.  This paper reports that SARS-CoV-2, the cause of the current COVID-19 pandemic, is inactivated in as little as one minute by copper alloy C110 (99.90% Cu).  


The paper that was published on January 2, 2021, in bioRxiv, a rapid publication service with only editor's approval.  This fast method of publishing was selected in order to communicate the ability of copper to quickly inactivate this virus in a timely manner.  Readers are encouraged to recommend that copper alloys be deployed in the fight against COVID-19.


In addition, a new paper containing these findings and results will be submitted to another journal to  undergo the more rigorous peer review process.

*EPA required statement:  Laboratory testing shows that, when cleaned regularly, antimicrobial copper surfaces kill greater than 99.9% of the following bacteria within 2 hours of exposure: MRSA, VRE, Staphylococcus aureus, Enterobacter aerogenes, Pseudomonas aeruginosa, and E. coli O157:H7. Antimicrobial copper surfaces are a supplement to and not a substitute for standard infection control practices and have been shown to reduce microbial contamination, but do not necessarily prevent cross contamination or infections; users must continue to follow all current infection control practices.
