GENEVA (Reuters) - Health workers will fan out in Guinea's capital of Conakry to try to identify people who may have been exposed to the deadly Ebola virus, the World Health Organisation (WHO) said on Thursday.

Tracing people in a city of around 2 million who may have had physical contact with infected people is harder than in the epicentre of the outbreak, Guinea Forestiere some 900 km from the capital, the United Nations agency says.
