Bacteria, microbes and viruses die when they come into contact with copper - this we know, and research has now shown the effectiveness of copper compared to other materials.
The novel coronavirus primarily spreads through respiratory droplets lingering in the air when you cough or sneeze, but the virus can also hang around on surfaces as well.
New experiments involved testing of SARS-CoV-2 (COVID-19) and SARS-CoV-1 (responsible for the 2003 SARS outbreak) on a variety of surfaces including cardboard, copper, plastic and stainless steel. The results followed the line of similar studies of the oligodynamic effects of materials and showed copper as a clear winner.
It was found that viable levels of SARS-CoV-2 were not detectable on copper after just 4 hours. Whereas it could last up to 24 hours on cardboard, and an alarming 2-3 days on plastic or stainless steel.
As economies are planning to restart, businesses begin to open and people set about going back to work – will the antimicrobial properties of copper help prevent the spread of coronavirus?
