A case of rubella has been reported at an Apple office in Ireland.
Public health officials are investigating the reported case at the giant Cork campus run by the technology firm.
Over 5,500 people work on the campus in Hollyhill on the northside of the city and staff there were notified about the case being discovered by an internal memo circulated over the weekend, Cork Beo reports.
The single case is believed to have been contracted in another country by an Apple employee who has been on campus in Cork.
Apple has yet to make a public statement on the case, but when contacted, a staff member said they are currently in contact with public health officials from the HSE and would not be making a further statement for the moment.
The HSE has also declined to comment on the case - saying its policy is not to identify outbreak locations where there are less than five patients identified.
Rubella has not been a major public health issue in Ireland for some years thanks to an extensive and effective vaccination programme which began in the early 1970s.
However, cases of rubella infection have been on the rise in the US and elsewhere - and are being blamed on the anti-vaccination or "anti-vaxx" movement, where parents are deliberately choosing to not vaccinate their children.
The anti-vaxx movement has been blamed for the return of a number of serious diseases which had been effectively controlled by global vaccination programmes.
Rubella is a virus that is - in most cases - a relatively mild condition that causes fever and rashes. However, it poses a significant risk for pregnant women as it can harm unborn babies
In cases where rubella - also known as the German Measles - are a concern, the HSE advice for pregnant women is to check their rubella immunity status with their GP.
There have been a number of cases of another relatively rare virus in Cork in recent months. In November, there were several cases of mumps reported at UCC.
And in early December, parents at one of Cork city's best known secondary schools were sent a letter by the HSE advising them to check that their children had been vaccinated after there was a reported case of the mumps.
The HSE advise all parents if they are unsure whether their child has been given the two doses of MMR to contact their local GP.
