Two questions about this:
Pyjamas that have been designed to protect hospital patients from the MRSA superbug have gone on sale in Marks & Spencer.
The £45 garment has silver thread woven into it, which tests show can reduce the spread of infections.
…Silver-laced nightwear has been tested in a handful of hospitals, but M&S has become the first retailer in Britain to stock the pyjamas.
1) Do they actually work?
2) If so, why is hospital issued nightwear not already using the technology?
