British born nurse, Pauline Cafferkey who worked in Sierra Leone during the Ebola crisis in the country has been re-admitted at the Royal Free London (United Kingdom) after she was transferred in a military airplane from the Queen Elizabeth University.
She contracted the Ebola virus in December, 2014, and was treated with an experimental anti-viral drug and blood taken from survivors of the disease. She spent a month in isolation at the Royal Free after which she was discharged in January, 2015.
Cafferkey is now in serious condition and will be treated under high-level isolation at the hospital. Also, a follow-up will be conducted on all the people who had close contacts with her for precaution.
It is believed that the Ebola virus can intermittently endure in certain tissues of the survivors for some months but the risk of transmission is low.
Cafferkey was among the winners of the Pride of Britain award which she got from the wife of the British Prime Minister, Samantha Cameron at No. 10 Downing Street in September.
