Pauline Cafferkey, the nurse who was rushed back to the hospital on Oct. 9 after seemingly contracting Ebola for the second time, has now shown "significant improvement" after being treated at the Royal Free Hospital in northwest London, according to Express.

Cafferkey was rushed back to the hospital earlier this month after becoming unwell in Glasgow. Back at the Royal Free Hospital, doctors stated that she has developed meningitis due to her previous infection, adding that she was "critically ill," which meant that she was at risk of dying due to the disease.

Thankfully, her body responded well to an experimental drug called GS5734, which has induced a "significant improvement" on the nurse. However, Dr. Michael Jacobs from the Royal Free Hospital states that Cafferkey's recovery is still a long road ahead, reported the Daily Mail.

"The last few days she has made a significant improvement. This is a highly experimental treatment. We don't know if it's of benefit to her," he said.

"I think she has a long recovery ahead of her. She will be with us at the Royal Free Hospital for quite a while still."

Dr. Jacobs further states that Cafferkey is still in an isolation unit in the hospital, though she is now able to talk to hospital staff and use an iPad without much difficulty.

The nurse previously contracted Ebola while working as a nurse at the Save the Children treatment center in Kerry Town, Sierra Leone, last year. Upon getting back to the U.K. in January, she was admitted to the Royal Free Hospital, where she remained in isolation for some time before being declared free of the disease.
