Third E. coli case confirmed in Orkney
A third case of E. coli has been identified in Orkney.
It has been confirmed that a person, previously showing no symptoms, has tested positive for the infection.
NHS Orkney launched an investigation after two children who attended the same nursery in Kirkwall contracted the illness.
The health board would not comment on whether the third case was also connected with the nursery. Officials are trying to find the source.
NHS Orkney said last week that other children and staff from the nursery were being screened as a precaution.
Dr Ken Black, consultant in public health medicine with NHS Orkney, said: "It is through our investigations that we have identified a third case and we are continuing to look for the possible source or sources of the infection.
"We continue to advise everyone to maintain vigilance concerning infection control.
"The spread of E. coli O157 infection can be prevented by following guidance on handling food and hand hygiene. As ever, anyone with health concerns should contact a health professional."
There have already been six other confirmed cases of E. coli infection in Orkney since August.
