Inactivation of Norovirus on Dry Copper Alloy Surfaces

Findings:

An inoculum of 5×104 pfu MNV applied to copper, and high copper content alloy. No infectious virus was evident after 30 minutes on copper and 60 minutes on copper nickel but there was no reduction of infectivity on stainless steel dry surfaces in simulated wet fomite and dry touch contamination. The highest rate of MNV inactivation on copper surfaces occurs upon immediate contact. The rate of inactivation was approximately proportional to copper content
