E.coli outbreak closes Tir Na Nog nursery in Bangor
A child who attends a nursery in Bangor and an adult with links to it have been diagnosed with E. coli, a month after an outbreak at a nursery on Anglesey.
Testing for the infection is being offered to children at Tir na n-Og nursery and the premises have closed.
Four people with symptoms who are close contacts of those who have been ill are being checked by Public Health Wales.
A possible link with an outbreak at a nursery in Amlwch, Anglesey, in October is also being examined.
Public health officers and environmental health teams from Betsi Cadwaladr University Health Board and Anglesey, Gwynedd and Conwy councils are investigating.
Nursery staff and those in at risk groups, who are close contacts of people who are unwell, will be tested, while parents have been asked to collect stool samples from their children as soon as possible.
Dr Chris Whiteside, consultant in communicable disease control for Public Health Wales, said a possible link with the outbreak in Tri Ceffyl Bach Nursery in Amlwch, Anglesey, was being investigated.
"We have two confirmed cases at present. Specialised laboratory tests will give an indication of whether they are the same strain as the Amlwch outbreak," he said.
"However, it will take some time before these results are available.
"E. coli O157 can have severe consequences for small children and as the illness can spread easily in nurseries and schools, it is important that all children attending the nursery are tested.
"No children or staff will be allowed to attend the nursery until they have received two negative tests for E. coli O157 taken at least 48 hours apart."
People can become infected with E. coli O157 by eating contaminated food, or through contact with infected people, farm animals or contaminated water.
"The infection can also pass from person to person and so it is important that anyone who is ill should observe strict personal hygiene to avoid spreading the infection," Dr Whiteside added.
E. coli O157 can cause diarrhoea, stomach cramps and fever.
The incubation period can range from one to 14 days, but is usually three to four days, and people with E. coli O157 are usually ill for up to two weeks.
The owners of Tri Ceffyl Bach Nursery in Amlwch closed it down indefinitely following the E. coli outbreak.
