London: The World Health Organization (WHO) has warned that the Ebola outbreak in West Africa 'could lead to failed states' threatening the existence of societies.
According to the BBC, WHO head Margaret Chan said that the epidemic has killed almost 4,000 people in West Africa that threatens world peace and security.
Chan also said that the rapid outburst of the Ebola virus is a historic risk.
Meanwhile, medics have ignored a strike call in Liberia that is the worst effected with the Ebola outbreak.
A union official said that the government had pressurized the workers but the government claims it had asked them to be simply logical.
