West African nations affected by the worst-ever outbreak of Ebola have been urged to screen "all people at international airports, seaports and major land crossings" in order to stop its spread.

The World Health Organisation said on Monday that authorities should stop anyone with signs of the virus from travelling, days after it warned that the magnitude of the outbreak was "vastly underestimated".

The WHO reiterated that the risk of getting infected with the virus on an aircraft was small and there was no need for wider travel or trade restrictions.
