Health officials have confirmed the first case of swine flu in NHS Grampian as the spread of the virus in Scotland accelerates.
The 23-year-old man contracted the virus while abroad although doctors insist there is no cause for concern.
He was one of 83 fresh cases revealed on Friday by Health Secretary Nicola Sturgeon, including two further patients hospitalised with the illness. The jump in confirmed cases is the largest daily increase in Scotland.
The announcement came as STV news learned that a helicopter travelling to a North Sea oil platform was redirected after a man on board began showing influenza-like symptoms.
The employee of Transocean subsidiary Sedco had been in contact with a confirmed swine flu patient. He was examined by a doctor in Aberdeen before being referred to his GP.
The case, which has not been confirmed, highlights how the virus could impact on industry. Businesses have been warned to be on alert and implement strategies to deal with the fallout.

Swine flu - school closures in Scotland
Colin Borland, from the Federation of Small Businesses, told STV news: "You have to be careful that if you employ three people and one of your members of staff is off - that's a third of your workforce down.
"You have to make sure you've planned for that eventuality. You have to make sure that you’re ready to take action. And you have to make sure it makes the minimum impact on your business."
Five schools in the west of Scotland have also been closed over swine flu fears.
Three schools in Glasgow - Drumoyne Primary, Nethan Street Nursery and St. Roch's playschool - and Glenfield Nursery and St. Paul's Primary in Paisley, will all shut their doors as community outbreaks of the virus continue to escalate.
There are currently 12 schools closed and nine partially closed in Scotland.
Medical experts are reiterating information to help people prevent spreading of the disease.
Dr Louise Smith from Abermed said "good hygiene" was key. She added: "If anybody's got sniffles or coughs or colds, or anything like that, the most important thing is to make sure you’re washing your hands, you’re disposing of tissues, you’re not touching too many people after you’ve been blowing your nose.
"Anybody who is worried that they've got flu-like symptoms, if they're feeling feverish or they’ve got coughs or colds or sniffles, they should be seeking medical advice. We would take it from there."
