First WHO Worker Catches Ebola

A staff of the World Health Organization has been infected with the Ebola virus.

The patient, a man from Senegal, is the first worker of the international body to catch the disease.

The WHO spokesperson has said that it is not yet clear how the man contracted the disease.

Ebola has killed over 1000 people in West Africa this year in an outbreak that the body has described as the worst ever.
