The Royal United Hospital has been free from the infection MRSA for 300 days.
MRSA is a type of bacterial infection that is resistant to a number of widely used antibiotics, meaning it can be more difficult to treat than other bacterial infections.
In the last 300 days, not a single patient has contracted the superbug while being treated at the hospital.
The RUH made preventing the infection a top priority, with posters on walls advising the importance of hand washing.
Senior infection and prevention control nurse Yvonne Pritchard said: “Being free of MRSA for more than 300 days is a significant achievement, which is down to the hard work of our staff in maintaining very high standards.
“Controlling and preventing infection is a major part of what we do here at the RUH and reaching this milestone is a real team effort.
“MRSA is mainly spread on hands, so good hand washing is the best way to stop it spreading.
“Everybody, whether they be staff, patients, or visitors, has a role to play in helping to prevent infection at the RUH by following good basic hand hygiene before and after meals and after using the toilet.
“We have done really well to have gone so long without an MRSA bloodstream infection, but we are not complacent – we are committed to being as safe as possible and our goal is to have not another case ever again.”
