Pauline Cafferkey has been admitted to hospital for the fourth time.
A spokesperson for Queen Elizabeth University Hospital in Glasgow confirmed to The Independent the nurse was admitted this morning.
They said: "Ms Cafferkey was admitted to the Queen Elizabeth University Hospital under routine monitoring by the Infectious Diseases Team. She is undergoing further investigations and her condition remains stable".
The 40-year-old nurse, who contracted Ebola in 2014, was taken to hospital by police escort. She has been hospitalised twice in relation to ebola and once more to be treated for meningitis.
It is unknown at this stage if she has been admitted in relation to Ebola on this occasion.
The medical worker from Cambuslang near Glasgow became infected with the disease when she was nursing infected people in Sierra Leone in 2014. She was volunteering with Save The Children at the time.
Following her diagnosis, she was treated in the Royal Free Hospital in London and discharged in January 2015. However, despite being declared fully recovered and no longer infectious, she was readmitted to hospital on two further occasions. In both October 2015 and February 2016 she returned for treatment due to complications linked to the disease.
Last month, Ms Cafferkey was cleared of professional misconduct after being accused of lying about her symptoms. She had been criticised for missing a screening upon arriving at Heathrow Airport when re-entering the UK and allowing her temperature to be mis-recorded, amid concerns she had been dishonest about the extent of her illness. However, a panel found that Ms Cafferkey had not sought to mislead any health officials and said screening staff had not been "properly prepared" to deal with the screenings, resulting in an environment which was "busy, disorganised and even chaotic".
