Efficacy of copper-impregnated antimicrobial surfaces against <i>Clostridioides difficile</i> spores
Copper coupons can substantially reduce <i>C. difficile</i> spores after 4 hours, but results vary depending on the initial spore concentration and presence or absence of organic material. Higher initial spore loads or excess organic material may prevent spores from contact with copper surfaces, thus decreasing kill efficacy. Continuous sporicidal effect of copper-impregnated surfaces may decrease spore burden and help prevent transmission of spores.
