Access to a premature baby unit at Bristol's Southmead Hospital remains restricted today following confirmation of the death of a child.
It's been confirmed that the pseudomonas bacteria contributed to the death in August.
During tests another 12 babies were found to have the infection on their skin. Of those, one was found to be infected but was allowed home after treatment.
Three remain in the unit in isolation while a further eight were discharged after being given the all-clear.
It's understood the baby which died was 24 weeks old. It's identity has not been released.
The babies currently in the unit are there because they are poorly, having been born prematurely, not because of the pseudomonas virus.
We have increased the levels of screening of the babies and cleaning of the unit and that level will remain until we are completely confident this issue has been resolved.
