How long does it take for the virus to inactivate on copper?

Question

Accepted Answer

The Novel Coronavirus Can Remain Viable on Copper Surfaces for Several Hours

The novel coronavirus can remain viable and infectious on copper surfaces for a significant period, with inactivation occurring over time. Specifically, it takes approximately four hours for the virus to become inactivated on copper.
Shortest Survival Time Observed on Copper

Research indicates that copper presents the least hospitable environment for the virus among the tested surfaces. The shortest survival time was recorded on copper, where half of the virus particles lost their infectivity within 46 minutes.
Inactivation Process on Copper

While the virus can persist on copper, the inactivation process begins relatively quickly. Within four hours, the virus is no longer considered viable on this material. This contrasts with other surfaces like plastic and stainless steel, where viable virus could be detected after three days.
Comparison to Other Surfaces

The persistence of the virus varies greatly depending on the surface. For instance, on cardboard, the virus was not viable after 24 hours. In aerosols, the virus remains viable for at least three hours, with a half-life of approximately 66 minutes for virus particles in airborne droplets.
