Karin Landgren, UN Secretary-General Ban Ki-Moon's special representative in Liberia said the magnitude of this outbreak requires a higher level of coordination than previous responses and the UN Mission in Liberia will play a strong role in this effort. Under the UN’s assignment, David Nabarro, a British physician arrived in West Africa on Thursday to supervise and coordinate acts to deal with the worst-ever outbreak of the deadly virus.

On the same day, a British citizen in Sierra Leone was reported to be positive to Ebola virus. This is the first British citizen to be infected with this virus.
