A nurse who was diagnosed with Ebola, the first Briton in the U.K., after working in West Africa was discharged from the hospital Saturday. She made a full recovery.

Pauline Cafferkey was diagnosed with the deadly virus disease on Dec. 29 after arriving in Sierra Leone. She had worked as a volunteer aiding in fighting the virus that had left thousands dead in that area. She was working with the charity Save the Children who are centered in Kerry Town in Sierra Leone.

More than one thousand nurses and doctors have put themselves at risk to volunteer in Sierra Leone since the summer. This was Britain’s first test at protecting their citizens from the virus. She received care at the Royal Free Hospital in North London. For more than three weeks, she was under special care in a high-isolation unit.

Cafferkey admitted in an interview with BBC that she thought about giving up when her condition became critical. She also explained that she had no sense of time and that she could not remember an entire week when the virus took hold of her body.

But in a statement released by the hospital, Cafferkey simply said that she is “happy to be alive.” She added that she does not feel 100 percent and she still feels weak, but she is “looking forward to going home.” Cafferkey concluded by thanking everyone who helped treat her and said “they were amazing.”

When she was admitted to the hospital, her condition immediately worsened. She was said to have been in critical condition for almost two weeks. Fortunately, doctors turned her conditions around and by Jan. 12 she was looking much better. It took only 12 more days to get her home.

The infectious-diseases specialist responsible for Cafferkey’s recovery, Michael Jacobs, credited his team. He said that it was their skill and hard work that helped her recover.

The hospital was also successful in treating another patient, William Pooley, who contracted the disease in West Africa. Royal Free Hospital is the main center for Ebola cases.

A mixture of treatments were given to Cafferkey, 39, in an effort to keep her alive. These experimental treatments included an unknown antiviral drug and plasma from Ebola patients who had recovered.

The European Medicines Agency or the U.S. Food and Drug Administration have yet to approve any vaccines or drugs for general sale or use. However, doctors have provided some patients with experimental drugs that have not been approved for sale. Doctors have used a drug called ZMapp and have seen some successful results, but the supplies for that medication have been drained.

An experimental drug called TKM-Ebola and blood transfusions were used to treat an American missionary, Richard Sacra, in the U.S. He contracted the disease in Liberia. And he was discharged from a hospital in Nebraska in September.

The most recent Ebola outbreak, which began in Guinea in 2014 and spread to Sierra Leone and Liberia, caused the death of close to 8,000 people. Early treatment or diagnosis, especially rehydration, greatly improves the chance of survival, but experts say the overall chances stand at 50 percent.
