Pauline Cafferkey, a nurse diagnosed with Ebola, was cleared of the disease and discharged from the hospital nine months ago. Now, she's battling against multiple complications and "has gotten worse."

According to edition.cnn.com, London's Royal Free Hospital said "Cafferkey's condition has deteriorated and she is now critically ill."

Cafferkey has been transferred from Queen Elizabeth University Hospital in Glasgow to London's Royal Free Hospital "due to an unusual late complication of her previous infection by the Ebola virus."

The hospital also said that Cafferkey is in "serious condition" and treated in "high- level isolation unit."

UK Health Secretary Jeremy Hunt has expressed his sympathy to the Scottish nurse's family as well as to the patient herself. The secretary tweeted "Sad to hear of deterioration in Pauline Cafferkey's condition. Thoughts & prayers with her & wonderful team looking after her @RoyalFreeNHS."

Cafferkey has been living a good life since she got discharged from hospital nine months ago. She also received a Pride of Britain award last month and she paid 10 Downing Street a visit where she was pictured with Samantha Cameron, the prime minister's wife.

Dr. Emilia Crighton, director of public health for the National Health Service for Greater Glasgow and Clyde, has also ruled out the possibility of Cafferkey "inadvertently passing" Ebola to others. She said that this possibility is "very low" even to begin with.

In a report by cbsnews.com, there are evidence that though a person got cleared and survived Ebola, mental and physical health problems can still occur for years even after the virus is cleared from the patient's bloodstream.

Thousands of Ebola victims in South Africa are still suffering from long- term effects of the disease after recovering from the virus.

Cafferkey returned on her duty as a public health nurse in Glasgow after being cleared and survived Ebola only to be fighting for her life after nine months against the same disease.
