Jennifer Scott was transferred by helicopter from Dumfries and Galloway Royal Infirmary earlier this week after she was diagnosed with a serious "flu type illness".
She is currently being treated at the Glenfield Hospital in Leicester where there is specialist equipment to deal with serious conditions such as this.
It was reported by the Scottish Sun that Ms Scott, understood to be 27-years-old and from Sanquhar in Dumfriesshire, was pregnant and collapsed during her mother's funeral.
At hospital, doctors performed an emergency caesarean section before Ms Scott was airlifted to Leicester, according to the newspaper.
A spokesman for NHS Dumfries and Galloway said: "We have had a confirmed case of a significant flu type illness.
"That case has been transferred and there are no other confirmed cases."
A spokeswoman for University Hospitals of Leicester NHS Trust said: "We can confirm that the patient has been transferred to Glenfield Hospital and is currently on a ECMO machine in ITU.
"The patient was flown to Glenfield Hospital as it is one of a limited number of hospitals in the UK that has this specialist piece of equipment. The patient is currently in a critical but stable condition."
