Use of copper can reduce infections in hospitals

Using copper alloy materials in a hospital setting substantially decreased the hospital’s bacterial burden, according to a new study published in the American Journal of Infection Control. This study shows for the first time that copper maintains the reduced bacterial load in both occupied as well as cleaned, unoccupied rooms. These results could reduce the number of health care-associated infections. Led by Shannon Hinsa-Leasure, associate professor of biology, the study found significantly fewer bacteria on copper alloy products such as grab bars, toilet flush valves, IV poles, switches, keyboards, sinks, and dispensers. Authors included Queenster Nartey ’16 and Justin Vaverka ’15.
