The hospital in north London that is treating a British Ebola sufferer has said that they are "pleased" with how he is responding to an experimental treatment.
They said William Pooley is "sitting up and talking to the nurses and doctors who are looking after him".
Staff said he was given the first dose of ZMapp on Monday and further doses are expected to be given to him "in due course".
Dr Mike Jacobs, consultant and clinical lead in infectious diseases at the hospital said, "We are giving him the very best care possible. However, the next few days will be crucial. The disease has a variable course and we will know much more in a week's time.
"Will is in a stable position and we are very pleased with where he is, we couldn't hope for more."
