A UK military nurse who contracted Ebola while volunteering in Sierra Leone has been declared free of the deadly virus.

Anna Cross, 25, from Cambridge, is the third UK worker to recover in an isolation unit in Royal Free Hospital in London. She says she now looks forward to doing "normal things like eating food and watching TV". It is not known how she caught the disease, which has claimed 3,764 lives in the West African country.

The virus which is transmitted via bodily fluids has a fatality rate of 50%.

Cross had been given the experimental Ebola drug MIL 77, which is similar to the treatment ZMapp that British nurse William Pooley received in August, 2014. However, it was unknown to what extent the drug played in her recovery.

Nurse Pauline Cafferkey also recovered from the virus in January 2015 after also contracting it in Sierra Leone. She was initially taken to a Glasgow hospital after her diagnosis before being transported to the Royal Free to be treated.

More than 10,000 people have lost their lives from Ebola in West Africa, with Sierra Leone, Guinea and Liberia being the worst affected countries.
