Pauline Cafferkey case shows we still know little of Ebola's long-term effects

Nurse's readmission with complications arising from infection is a reminder of how devastating virus can be even to survivors

Last week the Scottish nurse Pauline Cafferkey was in celebratory mood as she met the prime minister's wife, Samantha Cameron. She flew down to London after being selected for a Pride of Britain award by the Daily Mirror and joined other winners and families for a reception at No 10 Downing Street.

Cafferkey had contracted Ebola when volunteering for Save the Children's Kerry Town hospital outside Freetown in Sierra Leone last December. After successful treatment at the high-level isolation unit at the Royal Free hospital in London, she was discharged three weeks later.
