Copper Touch Surfaces

  1. 1. Copper touch surfacesGerms are a part of nature and we cannot beatnature. So hospital-acquired infections cannot betotally eradicated. But we can fight it more effectivelywith copper touch surfaces. A new way to containhospital-acquired infections lies in copper.The use of copper alloys for frequently touchedsurfaces as a supplement to existing standardinfection prevention measures, such as, hand-washing and disinfection regimens, has far-reachingimplications. Potential applications, which includedoor and furniture hardware, bed rails, intravenous (IV)stands, dispensers, faucets, sinks and work stations,can help reduce the presence of disease-causingbacteria in hospitals.
