Copper stopping infection

Clostridium difficile bacteria are present in our body as normal flora and without any harm. These bacteria become pathogen when the person uses antibiotics to treat any infection. These antibiotics kill the bacteria but provide opportunity to C.difficile to grow as pathogen. That is why antibiotics are not recommended to treat C. Difficile. This infectious disease is being spread around hospitals constantly, without nurses being assigned to isolation wards there is still a threat of repeat infection. There seems to be no cases of C.Diffiicile within the private sector so what is going wrong within our NHS hospitals. Before we spend more money on a scheme using copper plating to reduce the spreading of infection within wards, can’t we look at any other preventative methods?
