GENEVA (REUTERS) - The World Health Organisation's (WHO) emergency committee on Ebola will meet on Wednesday to review the scope of the outbreak and whether additional measures are needed, a WHO spokeswoman said on Tuesday.

"This is the third time this committee will meet since August to evaluate the situation. Much has happened, there have been cases in Spain and the United States, while Senegal and Nigeria have been removed from the list of countries affected by Ebola," WHO spokeswoman Fadela Chaib told a news briefing.

The 20 independent experts, who declared that the outbreak in West Africa constituted an international public health emergency on Aug. 8, can recommend travel and trade restrictions. The committee has already recommended exit screening of passengers from Guinea, Liberia and Sierra Leone.
