TWO nurses in two of Adelaide's major hospitals have tested positive for swine flu.
South Australia's chief medical officer Professor Paddy Phillips said both hospitals - the Royal Adelaide and Lyell McEwin - had undertaken infection control procedures to limit the spread and risk to patients, visitors and staff.
The Lyell McEwin Hospital nurse worked last Tuesday in a general ward but had not been at work since. She was confirmed as infected with H1N1 influenza late on Friday.
Patients she had been in close contact with have been treated with Tamiflu, with one still to be contacted.
The Royal Adelaide nurse worked on Thursday, became unwell and was confirmed as a positive case on Saturday.
"One patient was in prolonged contact with her and has been given Tamiflu as a precaution," Professor Phillips said.
He said the number of confirmed cases in SA currently stood at 262 and was continuing to rise.
"But it is important to remember that in the great majority of cases, swine flu causes a mild illness which people recover from without any medical intervention," he said.
