Ebola is 'most severe, acute health emergency'

More than 4,400 people have died from Ebola out of over 8,900 cases in seven countries. With the transmission of Ebola in Spain and the United States in recent days, there are heightened fears that the virus could spread to other parts of the world. The World Health Organization (WHO) has called Ebola "the most severe, acute health emergency seen in modern times".  Last month, United Nations Secretary-General Ban Ki-moon urged the worst-hit countries to establish special centres to isolate infected people.  The UN said aid pledges to fight the outbreak have fallen well short of the US$1 billion (S$1.27 billion) needed.
