Copper coated surfaces to control hospital acquired infections

Hospital Acquired infections can be controlled with use of copper coated surfaces.

As many 10% of the people visiting hospitals get infections from microbial contaminants from surfaces in hospital, there are very serious microorganisms which do survive to regular disinfectants and may get inside a healthcare professionals body.

One of such microorganism is MRSA methicillin-resistant staphylococcus aureus, this is very difficult to treat as the microorganism is resistant to most of the penicillin group of antibiotics.

Inorder to overcome hospital acquired infections, hospitals are required to adapt stringent cleaning and disinfecting procedures and disinfectants. Changing disinfectant periodically, also it requires to evaluate efficacy of microbial disinfectant used periodically for its effectiveness against all strains of pathogenic organisms with challenge tests.

Even after disinfection many microorganism like MRSA survive for weeks over table tops and floors of hospital causing infections to people who touch or come in contact with these surfaces.
Viable pathogenic microbial contaminants are found even over stainless steel polished smooth surfaces, supporting pathogenic microbial contaminants to harbour for weeks over them.

This can be controlled with a novel method, by coating surfaces of tabletops and surfaces which are more likely to get contaminated during patient examination and movement with copper metal fine beads or sheet is found to be very effective almost 90 percent of microbial contaminants bacterial as well as fungal do not survive over copper coated surface.

Copper has very good antimicrobial property against all sorts of microbial and fungal strains, copper releases copper ions which inhibit enzymes which are necessary for bacterial, fungal cells to growth. Copper ions owing to their strong ionic action over bacterial protein is able to kill bacterial as well as fungal cells. Similar property is exhibited by silver metal.
