A study has found that copper fittings rapidly killed bugs on hospital wards, succeeding where other infection control measures failed. It is believed that the metal ‘suffocates’ germs, preventing them from breathing. It may also stop them from feeding, and destroy their DNA.
During the ten-week trial on a medical ward, a set of taps, a lavatory seat and a push plate on an entrance door were replaced with copper versions. The copper items had up to 95 percent fewer bugs on their surface than non-copper versions whenever they were tested.
