After recovering from Ebola, British nurse hospitalized again with unusual late complication - A British nurse who successfully recovered from Ebola was hospitalized again on Friday for treatment of an unusual late complication, the Royal Free Hospital said.

Pauline Cafferkey was kept in isolation unit of the hospital and her condition was described as serious.

In December, Cafferkey was tested positive for Ebola after returning from Sierra Leone. She was treated at the Royal Free and discharged in January. On Friday, she was flown to London from Scotland, where she lives.

Medical authorities claimed the risk of her transmitting the virus is low, but Scottish public health officials have decided to closely monitor people with whom she had close contact.

According to experts, there are evidence to prove that the mental and physical health problems in Ebola survivors can last for years after the virus is cleared from the bloodstream.
